Abstract

1409460 Treating industrial effluents CIBAGEIGY AG 21 June 1973 [23 June 1972] 29544/73 Heading C1C Aqueous industrial effluent containing water soluble anionic dyestuffs or optical brighteners is purified by adding a water-soulble condensation product of dicyandiamide or dicyandiamidine, formaldehyde and an alkylene polyamine having 2 to 8 C atoms to the effluent and removing the flocculate which forms. Additional flocculating agents which may be used are iron salts and polyacrylic acid derivatives.
