Abstract

1480029 Cationic flocculants for water clarification AMERICAN CYANAMID CO 23 May 1975 [8 July 1974] 22970/75 Heading ClC A process for the clarification of raw water containing suspended solids therein, a portion of said suspended solids being colloidal particles of a diameter in the range of 0À09 to 1-5 millimicrons and contributing at least 0À5 Jackson Turbidity Unit to a total turbidity of said raw water in the range of 4 to 250 J.T.U., comprises: mixing said raw water with a polyquaternary flocculant which as a 37 weight per cent aqueous solution based on the cationic portion of said polyquaternary has a solution viscosity at 25‹ C. of 40 to 150 centistokes so as to form initial flocs which remain suspended in said water; allowing said initial flocs to remain suspended in said water until an effective amount of said colloidal particles are adsorbed thereto to form settleable floes; and thereafter settling the settleable flocs with their adsorbed colloidal particle content.
