Abstract

An algicide-flocculant solution for use in treating raw water in a municipal water plant to control algae, the algicide-flocculant solution including 25-50 wt % of an acidic flocculant, 0-10 wt % of a polymer flocculant aid, an algicide of essentially copper having a concentration of 0.025-1.25 wt % in the form of a water soluble capper salt, and balance water. Uniform mixing of the flocculant into the raw water simultaneously uniformly mixes the algicide of the algicide-flocculant solution into the raw water. The acidic flocculant is preferably aluminium sulfate, iron sulfate, iron chloride or mixtures thereof. The water soluble copper salt is preferably copper sulfate, copper chloride, copper nitrate, copper acetate or mixtures thereof. Moreover, the flocculant aid is a high molecular weight quaternary amine such as diallyldimethylammonium chloride.
