Equipment of a filtration for water

Any water where it was and by whoever it was cleared, first of all passes a stage of mechanical cleaning, that is from it the foreign debris having in the majority the size from 5 to 500 microns, and sometimes and moreover are removed. It is first of all sand, silt, and also a rust.
And undesirable rigidity ions, i.e. calcium and magnesium are the most widespread, first of all. Total content of these salts of rigidity in water is called its general rigidity. Presence at water of a large amount of salts does water in many cases unsuitable for its use in the economic and drinking purposes; and also in separate branches of the food and fermentative industry; coolings; steam-power economy; technological purposes of the industry:
For rigidity elimination by method of an ionic exchange or a kationirovaniye water is passed through a layer of a kationit. At the same time the cations of Sa and Mg which are in water exchange on Na cations which are contained in the applied kationit.
