A rough filter is a way to make water clean

Water, which is supplied to our homes and apartments, often does not meet even basic sanitary and hygienic requirements. A rough water filter will make the water in your housing one step closer to the one that is considered clean. In this article, we will describe what the device is, what kinds of it exist, and the basic rules for installing and maintaining a coarse filter for water.

Why do I need a water pre-filter?

If water comes from natural sources( reservoirs or wells) to a private house, it contains a large amount of dirt, organic matter, clay, fine grains of sand and other undesirable elements. In this case, no filter can not do.

Another thing - the city apartment buildings. The owners of such living space have doubts whether it is worthwhile to install a coarse filter, because water passes various types of cleaning, including mechanical cleaning, until it hits the apartment. However, do not rely heavily on such filtering, as the state of municipal, backbone and intra-house networks often leaves much to be desired.

Water, passing through pipes, entails splinters of rust and lime scale from their walls. Such water, which has abrasive actions, leads to rapid wear of gaskets and other sealing parts of sanitary ware, and also provokes the appearance of malfunctions in water flow meters.

Important! Especially dangerous is the water for household appliances: washing machines, water heaters, dishwashers.

An effective way to protect yourself from such problems is to install a prefilter.

Principle of operation of the

coarse water filter The operation of such devices is quite simple. Water passes through a filter in the form of a fine-mesh net of metal, which detains all the fine solid particles in it. After this, the de-watered water enters the draw-off points or is thoroughly cleaned.

Types of coarse filter

Devices can vary in their form, installation method in the water supply network, type of filter element. Despite all these differences, filters for rough water purification for home have the same principle of operation.

Mesh

The filter element of this device is a metal mesh. As a rule, it is made of stainless steel and has cells from 50 to 400 microns. This type of water purifier is the most common and popular, thanks to its long-term performance without the need to replace the filter elements.

The mesh device can differ in layout and method of insertion into the water supply system.

Flanged and boxed

The difference between these coarse filters is only in the way it is connected to the pipe:

• If the pipe diameter is 2 or more inches, then a flange cleaner is installed. Such a connection allows, if necessary, to remove the device without dismantling other elements of the system. Such an installation is provided in advance in the process of designing a water pipe.
• If the pipe has a small diameter, the filter is connected to it using quick-release union nuts or screwed directly onto the pipe.

Straight and oblique

All filters have a reservoir where water purification, inlet and outlet nozzles are carried out. Depending on the location of the settler, the filters are divided into oblique and straight:

• With a direct coarse filter, the settler is perpendicular to the downward flow. Its dimensions can be quite large, which improves the quality of the filtration process.

Important! When passing through a large sediment bowl, the water velocity decreases, and large particles of dirt settle to the bottom. After that, the water reaches the net and is cleaned of smaller suspended particles.

• The sump at the oblique filter is at an angle to the direction of the water. Such devices are used where it is impossible to use a filter of direct type due to lack of space. The sump at such cleaners is closed with a flange cap or screw stopper.

Muds with

flushing system Some direct filters and all skew are equipped with a cover that is removed. Their cleaning in case of obvious clogging is accompanied by disassembly of the entire device.

Direct filters with a washing system have a special outlet valve. Through it, you can drain the accumulated sediment and clean the devices with a direct or reverse flow of water.

Cartridge or cartridge

This type of filters are often used in domestic conditions. It is a wall-mounted design with a bulb of impressive size made of opaque or transparent material. The flask contains replaceable cartridges made of polypropylene pressed fiber, polyester or twisted yarn. The ability to clean such elements can be different. As a rule, for rough cleaning, cartridges of 20-30 microns are used.

Important! Flushing elements are not subject to washing. As necessary, they should be replaced with new ones.

How to install a coarse water filter?

To properly install a similar cleaner, you should follow some important recommendations.

Assembly rules:

• The best option is to install a coarse water filter in front of the meter. In most cases, because of the limited space, an oblique filter is used. Thus, you will protect the counter mechanism from clogging by large particles and damaging it.
• To facilitate the washing process of the oblique filter, it is placed flask down on the horizontal section of the pipe.

Important! It is necessary to take into account the direction of the flow of water indicated by the arrow on the body of the product.

• The oblique filter can also be placed on a vertical section of the pipe, but with the condition that the water will flow in a direction from the top down.
• When installing a direct filter, use only the horizontal section of the water supply.

Important! For cleaning work, consider the possibility of removing the bulb.

• Do not install the filter cover upwards. The sump of any device should be pointed down.

Installation procedure:

1. Disconnect all water supply.
2. Use the adjustable wrench to install the equipment.

Important! The filter of rigid water treating on a pipe is fixed by means of a carving or bolted connection with use of adapters, nuts, drifts.

1. Open the drain valves under the appliance and rinse the equipment.
2. Return the device to the operating position after 30 seconds.

How do I clean the coarse strainer?

Cleaning of similar equipment must be regular. Care of the filter elements will directly affect the quality of domestic water.

Procedure:

1. Shut off the cold and hot water supply.
2. Unscrew the sump lid using the adjustable wrench.
3. Remove the mesh and wash it.

Important! An old toothbrush will come to help in removing contaminants.

1. Install the mesh element in place.

Important! If the mesh is damaged, it must be replaced with a new one.

1. On the thread, rewind the insulation tape and replace the gasket between the sump and lid.
2. Tighten the cover securely.
3. Turn on the water and make sure that there are no leaks.

How do I clean the cartridge filter for coarse water purification?

As mentioned above, such filters are not cleaned in the usual way. They simply replace the old cartridge with a new one.

Procedure:

1. Shut off all water supply in the apartment.
2. Remove the flask and remove the clogged cartridge.
3. Reinstall the old filter element.
4. Install the flask in its place.

Important! Carefully screw the flask to the stop with a special wrench. This way you will ensure the integrity of the connection.

1. Turn on the water and check the system for leaks.

Important! Cleaning of filters with the washing system is carried out by regularly opening the crane located at the bottom of the bulb. Thus, the mesh and the flask are cleaned by the pressure of water. Dirty stream should be taken to the sewage system or collected in a pre-filled container.

How to choose a coarse water filter for a house or cottage?

When choosing this or that type of filter, consider some important parameters:

• Water pollution degree. This indicator can be determined using laboratory analysis. Based on the results, experts will help determine the choice of filter.
• Intensity of water use. The average water consumption per person is 200 liters per day.
• The size of the grid cell or cartridge. It is this parameter that determines the degree of water purification. To reduce the frequency of cleaning the device and increase its service life, you can consistently install two filters, first with a large mesh, and then with a shallow one.
• The choice of the cleaning device must also be based on the following characteristics: filter capacity, permissible temperature and pressure, cross-sectional diameter, type of connection.
