Filters water softening deferrization filtration

Filters for water softening ion-exchange technologies Water by passing through an ion-exchange resin changes its composition, thereby changing the hardness to the put no more than 7 mgm equiv. l The filtration volume reaches 10 m3 per hour. Hardness of drinking water is a characteristic of water, which is caused by the presence in the water of metal salts - calcium and magnesium. Rigidity is important for assessing the quality of any water used, industrial, drinking and water used for the needs of industrial enterprises with specified characteristics. The method for determining water hardness by hydrochemistry is: 1. 0-4 mEq / l - soft water 2. 4-8 mEq / l - medium hardness 3. 8-12 mEq / l - hard water 4. More than 12 mEq. / L - very tough. This applies to assessing the total mineralization of water; for drinking water, the Russian SanPiN defines maximum permissible concentrations of 0-7 mEq / l.
