WTEC - Model FAS Series - Double Layer Filters - Brochure

FAS multilayer filters can retain physical impurities, sand and mud, suspended substances in water, the iron in an oxidised form, which cause water turbidity. If turbidity is also caused by a modest quantity of fine colloidal substances (almost always present in surface watercourses) FAS filters offer excellent performance if used after an `in line` flocculation treatment, envisaging the direct dosage into the filter delivery lines of a specific product that aids the agglomeration of the dispersed substances into micro-flakes.
