The quality of water both in a private house and in a city apartment leaves much to be desired. To clean it, experts recommend using several stages of cleaning. The first stage of this procedure is carried out by installing coarse filters, the task of which is to retain mechanical elements, silt, sand, and rust particles that have entered the water.

Peculiarities

Coarse filters are designed to retain large particles (hard and soft), thereby providing primary water purification. When used in individual systems water supply, such devices mainly retain silt, sand, clay coming from wells or wells. At centralized water supply Such contaminants do not get into the water, but when water is transported through outdated pipes, rust particles end up in it. Wherein chemical composition water remains unchanged.

Coarse filters are also installed before installing meters, washing machines and dishwashers, which reduces the risk of breakdowns due to low water quality and thereby extends the life of the equipment.

Thus, among the main functions of coarse filters are the following:

• eliminating pollutants that could make water consumption hazardous to health;
• protection of the plumbing system (pipes, gaskets, connections and bends) from abrasive wear;
• preventing pipe clogging;
• protection of household appliances and water meters from damage and wear caused by exposure to polluting particles;
• elimination of foreign tastes and odors of water caused by the ingress of foreign particles into it.

Such devices may have different designs, dimensions, and degrees of water purification, but they all work on the same principle - they create a barrier to the passage of polluting particles and allow water to pass through.

Kinds

Depending on the features of the device, the coarse water filter can have one of several types.

Reticulate

The most affordable and simple, but nevertheless effective devices. Installation points - main cold and hot water supply in city apartments, point to the heating unit in private properties. In addition, there are filter meshes that are attached directly to the tap. They are excellent option for a dacha, since they are easy to install, and at the end of the season they can simply be removed and reinstalled on a tap in a city apartment.

The mesh filter can have different diameters of transmission holes - from 20 to 500 microns. The cleaning ability is due to the small size of the mesh cells. In addition, there are devices that are cleaned manually (mud collectors), as well as analogues that have a self-cleaning function and a system for draining contaminated water.

The mud trap can be straight or oblique. The first is mounted on horizontal sections of the pipe, the mud trap is directed downwards. The oblique filter is suitable for installation on both horizontally and vertically directed pipes. Depending on the type of installation, strainers are either coupling or flanged.

Modern products are equipped with pressure regulators, thanks to which it is possible to maintain constant water pressure. A useful “addition” is a double pressure gauge installed before and after the mud tank. If there is an excessive difference between the readings of the devices, it is necessary to clean the filter.

The advantage of mesh devices is their low cost and durability, strength, ease of installation, and the ability to install on hot and cold water. This makes it possible to combine them with meters and install them in front of each household appliance connected to the water supply system. However, such models only retain large particles, and if we are talking about a mud collector without a self-cleaning system, then it is necessary to clean it quite often.

Disk

The disc filter has special discs made of high-strength plastic, which are characterized by the presence of grooves of a certain depth. The principle of operation is based on the ability of the discs to compress, thereby forming a cylinder with grooves. The latter retain heavy suspended matter and allow water to pass through. The cleaning fineness is 5-250 microns. For convenience, many manufacturers paint wheels in different colors depending on the size of the cells.

Due to their high strength, increased productivity and resistance to high and low temperatures, they are widely used in industrial environments.

Cartridge

They are an element of a multi-stage cleaning system, which is usually mounted autonomously or under the sink. They provide a higher degree of purification compared to mesh models, since they trap particles 0.5-30 microns in size. They are suitable for retaining small debris. Devices are installed under the sink provided that the water flow is not intense. For stronger flows, autonomous analogues of higher power are required.

The principle of their operation is based on the retention of contaminants during the passage of cleaning compounds(granules), between which a small gap remains. And clay, silt and other similar impurities tend to settle on surfaces when the pressure of the water flow decreases, which is what happens when the liquid passes through the filter layer.

They are a housing filled with filter material. The body can be steel or plastic. The first ones endure high temperatures, are more durable and durable, but have a higher cost. Usually they are mounted on the hot water supply line, and for pipes with cold water choose more affordable plastic options.

However, the majority modern models plastic cartridges are characterized by versatility and are suitable for cleaning both cold and hot water. The advantage of such a housing is its transparency, thanks to which you can control the degree of contamination.

Polyester acts as a filter base(sometimes a filter non-woven material) or a mesh insert. The latter is usually removed from the device; it can be washed and returned to its place. Polyester analogues, as a rule, need to be replaced. The exact information about the possibility of washing or the need for replacement is usually indicated by the filter manufacturer.

Pressure

They are equipped with a pressure regulator, since in such filters water is supplied and purified under pressure. This becomes the reason for their bulkiness, however, it is the pressure devices that cope with the retention of different fractions of contaminants, which gives a high degree of purification.

Depending on the pipe diameter and performance, household and industrial devices, having the same principle of operation. The differences relate only to dimensions. The sizes of filter cells also vary, this, in turn, affects the degree of water purification.

Accessories

The filter device is quite simple. It is a mesh enclosed in a housing. The latter has an inlet and outlet pipe. Below the pipes there is a so-called settling tank - the place where filtration takes place. In this area, the speed of water movement decreases, so large particles (sand, rust, silt) settle in the body. The rest of the water tends to the grid, where it is also purified.

The material for making the mesh is usually steel, sometimes brass or bronze. In any case, it is a metal that can withstand contact with water, mechanical damage, and pressure well.

The filter housing (flask) is made of metal or plastic, and there are also combined models. Products made of steel, or having a steel box, are suitable for hot water pipes, plastic ones are used for cleaning cold water.

Polypropylene is most often used as the filtering components of a cartridge device. It provides high-quality filtration, is characterized by chemical inertness and resistance to biological factors.

Polypropylene is wound from the cord, so that large suspensions remain on the outside of the cartridge, and smaller ones settle on the twisted surface of the cord. They last for quite a long time and even when filled, such a cartridge does not cause a decrease in water pressure in the pipes.

Polypropylene cartridges can withstand temperatures ranging from 1-52C and are suitable for cleaning cold and warm water. Filtration of hot liquid is carried out using devices that have a cartridge made of fibers impregnated with a special substance based on cotton material. The impact temperature on the system can reach 93C.

Filter fibers can have additional carbon coating, due to which they acquire the ability to purify water from chlorine. Although this is usually the task of cartridges fine cleaning, which are installed after the type of device in question.

Well-known manufacturers and reviews

Today on the market there is a large number of primary water purification filters. The most famous, approved by customers, are the products of several brands.

• Honeywell. Compact devices that have several design options depending on the operating conditions. For cold water mains, devices made of transparent plastic are usually chosen, for DHW pipes purchase similar models that have a protective box made of brass. The advantage of devices from this manufacturer is that there is no need to dismantle the entire system for repairs or cleaning. The system is cleaned automatically. The collection of this brand mainly includes systems for industrial filtration, however, household filters are also available.
• Valtec. The products are made of steel and brass, which ensures their wear resistance, increased strength, and durability. They are equipped with a self-cleaning system and are capable of retaining particles no more than 100 microns. They have pressure gauges that simplify the process of managing the system, as well as indicators for monitoring the degree of filter contamination. Can be installed on pipes with hot water, since they can withstand up to 115-150C.

Valtec

• "Sapphire-P". Compact models (lower in height than many analogues), represented by filters for cold and hot water with manual and automatic control. They have the function of self-cleaning and regeneration through reverse current. In automatic models, you can set the period or amount of purified water, after which the self-cleaning process starts. They have a special controller that starts automatic cleaning after a specified period or after processing a certain volume of water. The required period or volume indicators are set through pre-programming by the user. The devices retain particles up to 100 microns in size and are suitable for household and industrial use.
• "Soyuzintellect". Filters of universal action, providing not only mechanical, but also sorption and antibacterial cleaning. In addition, in such filters the water is saturated with oxygen. This, in turn, makes it possible to reduce water consumption (the amount of liquid decreases, but does not in any way affect the user’s sensations), improves its quality (the water becomes more voluminous, foams, and soap or detergent lathers better in such water).

The developed line is suitable even for pipes with high water pressure and can be installed on hot water mains; the devices are resistant to corrosion.

Sapphire –P

• "Geyser". The Typhoon line has gained the most popularity. Available in a metal filter, suitable for hot and cold water. The equipment serves not only to retain impurities, but also to soften water with a high iron content. Models for very hard water are also available. Three-stage purification systems are becoming increasingly popular, in which the first stage of purification is carried out by coarse water treatment systems.
• "Barrier". The products are easy to use and affordable. For a long time, the company's specialization was the production of cassette filters for jugs, but today the main activity is the production of stationary filters. These are cartridge-type filters, when used, as users note, better side The taste characteristics of water change and the unpleasant odor is eliminated.

• "Aquaphor". Company long time(about 15 years), is engaged in the production of various water purification systems, and therefore its range includes a large number of manual and automatic coarse filters. Buyers are particularly trusted by “under-sink” systems, which can be installed on hot and cold water supply pipes.

The disadvantage of these models is the labor-intensive installation, however, if you purchase the product from official representatives, the installation will be performed by professionals for free.

How to choose and install?

Important selection criteria are the size of the retained contaminants and productivity. The performance of the filter is determined by the volume of water being purified and the required amount for a particular user. At the same time, high productivity should not cause a decrease in water pressure in the tap.

When using low-capacity filters, you can mount storage capacity , where purified water will flow while the tap is closed. After the tap opens, the purified water accumulated in the container is consumed.

The size of the cells or mesh should be selected based on the quality of the water, the nature and size of the impurities. If the size of the filter elements exceeds the size of the polluting particles, the filter will have no effect.

When using fine-fraction systems to purify heavily contaminated water with large particles, the filter will have to be frequently removed and cleaned, and its elements replaced. Intensive use under such conditions increases the risk of premature filter failure.

A preliminary laboratory analysis of the water will help you make sure you don’t make a mistake in choosing a filter. Based on the results of assessing the water quality, experts will recommend the optimal type of filter. In some cases, it is beneficial to use 2 mesh filters installed in series with larger and then smaller cells. This will reduce the frequency of cleaning and extend the life of the device.

A gearbox will also be a useful addition to the filter. It reduces the water pressure at the entrance to the filter, and also dampens water hammer in the system, which provides better cleaning and allows you to extend the life of the device.

Due to their structural features, direct filters demonstrate greater efficiency compared to oblique filters. It is better to choose the latter only if it is impossible to install a straight model (usually this happens when there is a lack of free space, for example, when the pipeline is close to the floor or another pipe).

For country house It is recommended to install 2-3 mesh filters of different mesh sizes. As a rule, coarse-grained protection is installed in a private house, while for a city apartment it is better to choose a more dense mesh.

Before washing and dishwasher It is recommended to install additional filters. Ideally, they are needed in front of every household or engineering device, but this is expensive. But it’s still worth installing a filter in front of the washing machine and dishwasher; this is a rather demanding equipment in terms of water quality. Moreover, the more expensive, the more capricious.

When purchasing a filter, you should pay attention to the materials - they should not only be durable, but also environmentally friendly. All connecting and threaded elements must be securely fixed, rubber gaskets and seals must fit tightly to the structure.

It is important to understand how necessary certain functions are, since their presence increases the cost of the product. For example, devices that soften water with excess iron are very popular. However, it will be useless if there are none. Moreover, the water may contain excessive amounts of manganese and potassium ions that need to be reduced. The type of product in question in this case will also not cope with the task.

The way out of the situation, as already mentioned, is a preliminary laboratory study of the quality and composition of water.

Only based on the analysis data obtained should you purchase a filter.

There is an opinion that it is better to give preference to equipment Russian manufacturer , since it is best adapted to the composition of the water in the surrounding areas. Leading positions are occupied by companies such as Aquaphor, Geyser, and Barrier. Among foreign filters, German and Scottish brands enjoy the trust of buyers.

The method of installing the meter is usually determined by its type. Professionals advise using detachable connections for all types of devices - both for those who need to be removed and washed, as well as stationary, bulk ones. This will simplify the process of dismantling the device if necessary to repair it. Correct installation Making main filters with your own hands begins with cleaning the surface of the pipe, removing traces of rust, and checking its tightness.

Water filtration today is very important given the level of pollution environment and the condition of water supply pipes. This is equally true for country houses, receiving the necessary liquid mainly from wells, and for apartments multi-storey buildings connected to city highways. In this article we will look at coarse and fine filters used in everyday life.

General provisions

Water from a tap in an apartment or from a well in a country house is not poisonous, which is used by skeptics as an argument that there is no need for additional forced filtration. But let's look at this problem more carefully.

City water supply

There are two particularly negative circumstances here:

1. The deplorable state of the city water supply, many elements of which have not been changed for decades. The accumulated debris, rust, scale and other insoluble substances again contaminate the liquid purified at the treatment station. And this poses a danger not only to the human body, but also to all household plumbing equipment, including a washing machine.

1. Chlorine. Chlorination as a means of neutralizing drinking water has not been used for a long time in most civilized countries, since bleach itself is a poison, and nothing good can be expected from its frequent use. Sometimes, with an increased content of this element, even when visiting a bath, you experience unpleasant sensations in the form of dry, tight skin.

Autonomous water supply

Here you yourself monitor the condition of the pipes and do not use harmful chlorine, but particles of sand, clay, organic matter and heavy metals may come across. If you have drilled an artesian well, then a large number of natural filters in the form of layers of sand and clay reduce possible contamination to a minimum, but a sand or ordinary well cannot guarantee the absence of the mentioned impurities in dangerous quantities.

Advice: when installing sand wells and wells, try to place them at a distance of at least twenty meters from street toilets, cesspools and compost heaps.
Otherwise, the produced water will become even more polluted.

Coarse mesh filters

These are the first filters for water supply in a private home, which must be installed without fail if you want to avoid sand and other insoluble substances from getting into sensitive plumbing equipment, into the food you prepare and into drinking water taps.

If you only have a fine filter, it will quickly become clogged with large particles. As we have already found out, this also applies to apartments, since rust from the water supply can have an even more disastrous effect.

The main element in this model is a grid of of stainless steel with a cell size of 50 to 400 microns, which retains insoluble particles.

This filter is very popular due to the simplicity of its device, which provides the following positive qualities:

1. Simple installation instructions. You just need to screw it between the joints of two pipes.

1. Convenience Maintenance. How to clean the coarse filter on a mesh-type water supply?
   For this it is enough:

• Unscrew the locking cover with an open-end wrench.

Tip: while unscrewing the lid, hold the junction with the water supply with another key so as not to break the seal of the joint.

• We take out the mesh with our own hands.
• We rinse it, removing accumulated dirt.
• Reinstall and screw the lid back on.

1. Relatively low price.
2. Durability.

Mesh filters, in turn, have several differences:

Thread or flange

A flange connection is used when the pipe diameter exceeds two inches, which usually concerns water mains or basement junctions apartment buildings. In apartments and private houses themselves, threaded ones are more convenient.

Straight or oblique

Each filter for country water supply consists of two connection pipes and a special tank in which the filtration itself is performed.

So this tank can have two positions:

1. Direct. In this case, the sump is located perpendicular to the pipeline and can be large in size, which significantly improves its operation, since the passage of liquid then slows down, and most of the debris has time to settle to the bottom, and smaller fragments are stopped by the mesh. But this option is very difficult or completely impossible if it is close to a wall or vertical.

1. Oblique. Placing the sump at an angle to the direction of water flow is used in cases where compactness and versatility are required. That is, such devices can be easily mounted in cramped conditions and can be installed on vertical pipes.

Mud traps or washable

The cleaning method may also differ depending on the design of the device:

1. Sump. All oblique and some direct filters are equipped with this system. In order to clean them, it is necessary to carry out the process described above, which includes removing the cover and removing the mesh out.
2. Washing system. Sometimes the direct filter is equipped with a special drain valve, which allows you to drain dirty sediment and backwash with clean water.

Installation subtleties

You can install the pre-filter yourself, but you should follow some recommendations:

• The device should be installed before the meter, since it can also fail if sand or rust accumulates in its structure.

• Mount the oblique structure on horizontal sections with the bulb down, which will facilitate its further cleaning. On vertical ones, installation is possible only in case of movement from top to bottom, be sure to take this into account.
• For direct filters, choose a place that is spacious enough to remove the capacious flask.

Cartridge filters

If you want to get clean drinking water at the point of water intake, then you should not limit yourself to coarse cleaning and install in addition a fine filter, which can have a simple structure of one large flask with a replaceable carbon cartridge or be an entire filtration system. The first option is quite cheap, but the result is not guaranteed.

The second, of course, is very expensive, but the output also provides a perfectly clean liquid.

Advice: it is not recommended to purchase intermediate models that, for example, have three flasks.
They cost more, but the effect is approximately the same as with one cartridge.
So it’s more rational to buy either a simple filter, or invest in a full-fledged system with reverse osmosis and a set of compartments for various purifications.

A sample with one flask is similar in structure to a coarse filter with a direct settling tank, but we will analyze the system in more detail:

Designation in the figure	Name
1	Triple adapter
2	Body part with pre-cleaning compartments
3	Electric pump
4	Toggle switch for low pressure
5	Reverse osmosis membrane
6	Toggle switch for high pressure
7	Flow restricting element
8	Electromagnetic flushing valve
9	Drain coupling
10	Storage tank tap
11	Storage tank
12	Carbon filter
13	Mineralizing filter
14	Clean water tap
15	Key for pre-cleaning housings
16	Electronic controller with digital display
17	Solenoid valve

As you can see, after passing through so many filtration compartments, the water becomes perfectly clean.

All cartridges, including the reverse osmosis membrane, are periodically replaced, which leads to additional costs.

It should also be noted that the installation of this equipment is carried out exclusively by classified specialists.

Conclusion

Unfortunately, water from a city water supply or from a well is no different perfect cleanliness and needs filtration. First of all, care must be taken to remove insoluble particles, which are harmful not only to human body, but also for all plumbing equipment, and install a coarse filter. Next, you should think about fine cleaning, which will make the liquid harmless to drink.

The video in this article will provide you with additional information.

Clean water is the key to your health.

When arranging water supply systems, few people pay attention to the installation of filters that purify the liquid. Meanwhile, it is filters that are the first and most reliable barrier that protects us from pollution and various deposits in the water.

After all, water, whether it is pumped out of a well, may well be contaminated with various impurities, bacteria or even sand. It is prohibited to use it in this form, as everyone knows.

Therefore, if you don’t want unnecessary troubles, then it is better to install special mesh filters. And before purchasing them, it is better to understand all the features and nuances of this equipment.

1 Purpose and principle of operation of mesh filters

We all want to drink clean water. Reasonably distrusting quality tap water, as well as any other water obtained within the city, people set themselves various systems water purification.

This can be a single cartridge filter or a multi-stage installation. It all depends on the initial quality of the water and the buyer’s ability to pay.

Purified water is necessary not only for our health, but also allows us to protect and extend the life of various household appliances (washing machines, humidifiers, dishwashers, etc.), pumps, mixers.

Among the great variety of filters and cleaning systems, the so-called mesh filters stand out. What's so special about them?

The fact is that a strainer in one form or another is installed in any water supply system: at the entrance to washing and washing machines, before fine water filters, before pumps and tanks. Even an ordinary tap is often equipped with a small mesh, which is essentially a coarse mesh filter.

The simplest mesh filter consists of a metal body, connecting flanges (or pipes) and a cylindrical filter mesh located inside the flask. The body-flask is closed with a plug nut (in non-flushing devices) or a special tap (in flushing and self-flushing devices).

Now let's look at the main advantages and disadvantages of these filters. They must be taken into account if you are going to make the right choice.

The main advantages of a mesh filter over others:

• very simple design;
• ease of maintenance, does not require special equipment and skills;
• possibility of washing and restoring functionality,
• cheap components - replaceable mesh;
• relatively low price;
• environmental friendliness - no replaceable cartridges made of synthetic materials.

Like any device, there are also disadvantages:

• traps only fairly large contaminants (particle size 100 microns or more), although filters for finer fines are already being produced mechanical cleaning water;
• It purifies water only from mechanical impurities, but does not eliminate chemical and biological contaminants.

Based on the information above, we can conclude that it is advisable to install mesh filters for water purification in everyday life:

• with old, rusty water supply networks, which can clog the water with rust particles and other debris.
• in front of any equipment connected to the water supply ( geysers and boilers, washing machines and dishwashers, water meters, toilet cisterns, etc.).
• as a method of preliminary water purification before finer purification devices;
• to protect pumps and other water supply devices from wells (wells) from sand, clay, and other impurities.

2 Types of mesh filters

Mesh filters are straight and oblique (y-shaped), for cold (with a transparent plastic flask) and hot water (with a metal flask), and are also divided into non-washable, rinsable and self-cleaning.

Non-rinsing samples are filters of the smallest dimensions, and they can be cleaned by unscrewing a special nut located on the device flask, removing and cleaning the mesh manually. Before cleaning, turn off the water supply taps.

Sometimes such a filter device is equipped with two pressure gauges, so that their readings can be used to judge the degree of contamination. In this case, its size will inevitably increase.

Advantages: small sizes, low price, easy installation and operation, low price.

Disadvantages: the need for regular manual cleaning, relatively short service life.

There are a few things you need to know before you go shopping for a strainer.

First, determine the purpose of the installation. To protect most equipment from mechanical contamination, it is enough to have a coarse filter, the replaceable mesh of which has cells measuring 100 microns.

For better purification of water intended for drinking, it is worth purchasing an additional fine filter (50 or 20 microns).

Then the connection method itself is taken into account - using flanges, external or internal threads, as well as connecting dimensions, for example ¾``, ½``. Threaded connections - up to 2" and flanged connections - over 2 inches.

The position of the pipeline - vertical or horizontal - will also play a role. The working position of flushing and self-cleaning devices is on a horizontal pipeline. In a vertical position, only universal filters from some manufacturers that are specially designed for this purpose are effectively cleaned.

In addition, some advanced models are equipped with rotating flanges that allow the installation of even coarse and fine wash filters on vertical pipelines.

It is also worth considering the size of the filter installation area - the small size of the installation space may limit the choice. The smallest dimensions are the usual non-flushing ones, which are two times shorter and less in height than the others.

You need to be very careful with the dimensions, since a lot depends on them. A discrepancy in size will make even the best and most advanced filter completely unusable. And you won’t be able to change anything, since such equipment cannot be modernized or modified.

Therefore, when choosing sizes, always take into account the dimensions of the pipes, nominal positions in the system and all other parameters.

Thus, if you need to protect equipment from mechanical impurities and you are not limited in the amount of space for installation and finances, then best choice There will be a self-cleaning coarse filter from the German company Honeywell with a stainless removable mesh, the cell size of which is 100 microns.

At the same time, it is better to choose a filter element with backwashing, as it is much easier to work with. And you will have to wash the filters quite often. Especially if you have contaminated water in your system.

3.1 Operating principle of an industrial water strainer (video)

Water coming through pipes or from a well contains a variety of biological and chemical impurities, as well as mechanical impurities, which can be dangerous both to human health and to complex household appliances and expensive plumbing fixtures.

Helps remove large impurities main water filter.

It is installed directly at the entrance to the house. Also, such devices are also called prefilters. They retain grains of sand, silt and other contaminants and prepare the water for further purification with other filters.

Those who purchased expensive household appliances, probably was warned that the manufacturer’s warranty will only be valid if there is a filter at the inlet, that is prerequisite is pre-cleaning. Plumbing reacts to the quality of water, stains and deposits may appear, connections begin to leak, and the gasket needs to be replaced more quickly.

Even water meters may not be able to withstand dirty water and fail.

If there is a fine filter in the house, then the pre-filter will make its work easier, and cartridges will need to be replaced less often.

VIDEO REVIEW

In city apartments, the installation of different main devices for both types of water is required. In this case, a cold water filter should never be used to clean hot water.

Based on the type of cartridges, the following types of devices are distinguished:

• mesh,
• corrugated,
• winding filters.

Equipment may also differ in the degree of cleaning

According to this indicator there are:

1. single-stage - for removing rust, sand, sediment,
2. two-stage - additionally removes chlorine, clay, organic matter, unpleasant odors,
3. three-stage - make water softer, remove iron.

Before purchasing a main device, it is important to decide on the following parameters:

• type of line (hot or cold water),
• required level of purification (mesh or cartridge filters can be used),
• body type (for high water flow - Big blue, for small Slim Line),
• level of hydraulic losses (the higher your apartment, the lower the losses should be),
• type of cartridge (selected after water analysis).

Rating of the best coarse water filters for home

Geyser main filters— used for cleaning and conditioning water for domestic needs. They perform a whole range of tasks - from the simplest to complete reverse osmosis purification, as a result of which the water becomes completely suitable for drinking.

The body can be made of plastic or stainless steel. Presented big choice cartridges for water purification of any level of contamination. Replacing equipment cartridges is quite simple, and the devices themselves are durable and reliable.

Another market leader is the company Aquaphor, offers Viking models for installation in a city apartment or country house. Effectively remove sand and rust, pesticides, heavy metals, and unpleasant odors.

The durable metal housing ensures resistance to mechanical stress and high pressure.

Is different high speed cleaning - about 25 l/min. The compact design allows you to place the equipment in inconvenient and hard-to-reach places.

Honeywell coarse water filter is deservedly considered one of the best, its advantages:

• Patented backwash mechanism
• no need for cleaning,
• increased reliability and durability.

They are not afraid of pressure surges and are easy to install and use.

The Israeli company Arkal produces no less high-quality coarse flow filters for water than the previous manufacturer. Their products are not yet so popular in Russia, but they are very often used in European countries. The main cleaning element is polymer discs that are resistant to corrosion and pressure surges.

Installation instructions - how to unscrew the coarse water filter

At installation of a coarse water filter You should rely on the arrow pattern on the body, which shows the direction of the water flow.

If the filter is to be cleaned, a bypass line will need to be installed.

In general, the procedure will be as follows:

1. Install the equipment using an adjustable wrench. For a perpendicular filter, the dirt trap should be positioned with the lid facing down to allow dirt to accumulate.
2. Flush the equipment by opening the drain valves under the equipment.
3. After 30 seconds, you can return the device to its working position.

Do-it-yourself cleaning of the coarse water filter mesh

If you need to replace the device with a new one, follow these steps:

• Turn off the water and leave all taps open to reduce the pressure. Then close the taps back.
• Use a wrench to twist the old filter and remove the clamps from the wall.
• Remove the old seal and apply new insulating tape.
• Attach the device to the wall.
• Turn on the water and check for leaks.

Are there any differences between coarse water filters for a country house?

Coarse water filters for summer cottages have a number of differences from similar equipment for use in city apartments. First of all, the difference is explained by the composition of the water. In the city, water is characterized by increased hardness, and in the countryside many encounter the smell of hydrogen sulfide and the taste of metal.

Also, the selection of equipment is carried out taking into account the source of water intake, because water outside the city does not undergo pre-treatment and comes directly from a well or borehole.

IN individual houses it is possible to use more wide range equipment, since there are usually no problems with free space for devices. For this reason, many install more complex integrated systems of not only coarse, but also fine water purification.

Some manufacturers offer universal devices that can be used both in a private home and in an apartment. Before purchasing such a device, it is still recommended to carry out a water analysis and understand whether it is suitable for water purification in your area.

The first level in a well-organized high-quality water filtration system is a coarse filter. This is a small device designed to collect mechanical impurities and dirt particles contained in the consumed liquid. One type of such device is a mesh filter for coarse water purification with varying levels of contamination. The equipment is in great demand because it differs:

• simple installation and easy maintenance;
• affordable cost with fairly high efficiency;
• wide model range devices - are manufactured for the purification of water containing insoluble suspensions of various sizes. The mesh is capable of trapping particles with a diameter of 50 to 500 microns.

Mesh devices can be used as independent filters or be an integral part of the circuit quality system filtration. They effectively remove rust and sand from water, as well as foreign particles that get into it when the substance passes through rusty, encrusted and unrepaired pipes. After cleaning the liquid from impurities and dirt particles, it does not become 100% drinkable, but the use of such water (without mechanical suspensions) is of particular consumer importance. A correctly selected and installed mesh water filter improves the quality of the substance, which means:

• protects water heating and water consuming equipment from premature failure;
• reduces the intensity of clogging of fine filters;
• reduces the cost of purchasing consumable filter elements;
• increases performance characteristics ultrafine purification and mineralization filters.

The advantage of a device for coarse water filtration is its versatility. Manufacturers produce Various types mesh devices, which are installed directly on the pipes of the water supply system. What types of mesh filters exist? How to choose a device?

The principle of operation of the mesh filter and its types

The main filter element of the device is a mesh (cylindrical) with permeable cells of a certain diameter. It is usually enclosed in a stainless steel case, which can be equipped with a special plug in the form of a nut or a tap. The shape of the body resembles an elongated flask with outlet pipes (flanges for easy and quick connection of the device) and a container for waste substances (sump).

Installation of a water filter mesh is carried out at the water inlet into a house or apartment. The installation location is selected before the pipeline is laid out to the water supply points. If water meters are provided, then the device is installed in front of the meter. When the tap is opened, the substance passes through the pipes, overcoming the obstacle in the form of a mesh filter element. It traps all undissolved impurities with a diameter larger than the diameter of the permeable mesh cell.

Since the operating conditions of the mesh filtration element can be different, manufacturers offer several types of devices for rough water purification:

• Oblique and straight mesh filters.

The division into straight and oblique devices is carried out according to the placement of the sump. In the first case, the container is positioned straight down. That is, perpendicular to the flow of water. Their distinguishing feature is their size. To install a straight mesh filter for coarse water, you need a lot of free space in the area under the pipe. But it is the increased dimensions of the vertical container that provide better filtration. For oblique mesh filters, the container is placed at an angle to the water flow in the pipe. They are convenient to use on pipes that lie close to the floor or are laid vertically.

• Coupling and flange mesh filters.

The division is carried out according to the method of installing equipment on water pipe. Flange devices are suitable for pipelines with a diameter greater than 2 inches (junctions, main systems, etc.). Their main advantage is simple and easy dismantling due to studs and bolts. The second type of fixture is suitable for pipes with a diameter of up to 2 inches. They are screwed onto the water supply, making them difficult to remove.

• Mud traps and washable filters.

The separation of coarse filters is also carried out using the method of cleaning a settling tank. Devices that cannot be washed manually are mud collectors. These include oblique and some groups of direct filters. They are equipped with a special lid for ease of use. In direct filters, where the mesh for the coarse water filter is placed perpendicular to the water flow, a tap is provided to release the waste liquid.

Pros and cons of a mesh filter for coarse water purification

Filters for coarse filtration of substances are produced by many manufacturers. But only a few brands offer devices adapted to difficult operating conditions:

• Valtec;
• Honeywell;
• ITAP and some others.

These same manufacturers also put on the market Consumables for devices - mesh for coarse filter and other elements. Of course, such filtering equipment has a rather low degree of purification of the substance, but, taking into account the state of the water supply systems in 87% of residential buildings, it is simply impossible to do without them. Mesh filters - cheap way purify water from mechanical particles undissolved in the liquid, which has a number of advantages:

• there is no need to purchase additional equipment for maintenance and installation;
• no skills are needed to install and clean the sump;
• restoration of effective performance;
• cheap components;
• high levels of environmental safety;
• economical maintenance - replacing the mesh is carried out less frequently than changing cartridges.

When purchasing a mesh filter, pay attention to the size of the element cells. For rough cleaning, a 100 micron mesh is sufficient. Do not forget about the specific location of the pipes and their diameter. Having decided on the parameters, you can make a purchase.
