Automatic aeration water deferrization filters remove iron divalent, hydrogen sulphide, magnesium and mechanical impurities from the water. This is due to the aeration principle. 

The automatic water deferrization filter AFT oxidizes the dissolved in water iron  and removes it. The filtering system consists of an aspirator (air pump), an oxidation tank and a deferrization filter.

This filter is designed to remove solid particles, iron, manganese and hydrogen sulfide from the water. The principle of action of the filter is based on oxidation of the elements dissolved in water and their transition to a condition of insoluble. The insoluble deposits are collected on a filtration filler.  

Cartridge filters of deferrization are intended for removal from water of firm particles, iron, manganese, hydrogen sulfide and their connections.
