Main filters for water treatment: basic types and functionality

As is clear from the title, the main water treatment filters are designed for installation in a water main. To adapt this type, a parameter such as bandwidth is very important . Its value can reach fifty liters / minute. This is the case if the model is designed for a small house or apartment. In each specific situation, the maximum amount of water that can be required is estimated, that is, it is necessary to calculate the peak consumption.

In addition, the main water treatment filters should have minimal effect on the pressure in the water supply. Modern models lead to its fall by half a bar. A greater value is undesirable, especially if the pressure initially is not too high.

These devices can belong to several types, depending on the purpose. The main coarse filter is designed for the removal of large mechanical impurities. It should be placed at the entry point of the water main. This will allow all plumbing and equipment in the house to work with purified water. Installation of such a device is also necessary for the normal operation of fine filters. The main filter element in such systems is a metal grid with small cells. Some devices have several degrees of purification, while the size of the cells gradually decreases. The lifetime of such a device is almost unlimited, but the grid needs to be periodically washed, as it can clog, and this sometimes causes the main line to shut off.

The main filters for water treatment can be designed for both cold water and hot water. They differ in the materials used for production. For example, the body is made of plastic, resistant to overheating, or stainless steel. The cartridge for hot water systems is made of polymers that are not inclined to change their properties during long work with hot water. The device for hot water can be used to work with cold water, and vice versa - not.

The main filter of fine water purification is connected after the device for rough cleaning. In such systems, several technologies are usually combined. Almost always there is a disposal of small mechanical impurities, and also sorption cartridges are used. In addition, such filters can be supplemented with ultraviolet processing modules, as well as various membranes.

Fine cleaning is most often used for water used for drinking or cooking. Water for technical needs must be mitigated. At the moment, the main line softeners, which use sodium polyphosphate as a reagent, have become very popular. Such water can not be used for cooking without additional treatment. The magnetic softener is more popular, which can be installed at the entrance of the mainline after a coarse cleaning device, or even directly in front of household appliances. It is effective for water of any temperature.

Now you know what the main water filters are for.
