Abstract

1450673 Purifying aqueous liquid by flocculation VATTENBYGGNADSBYRAN AB 2 May 1975 [9 May 1974] 18546/75 Heading C1C The invention comprises a method of purifying aqueous liquids by chemical precipitation and filtering, wherein flocculation is initiated in a volume of liquid above a filter-bed in a filter in which the liquid flows downwardly, by blowing a gaseous medium into said volume of liquid, or by mechanically stirring it, the floc comprising impurities initially present in the liquid and a precipitating agent utilized to precipitate said impurities. Suitable precipitating agents are aluminium, iron or magnesium salts, lime, or a combination of these.
