Abstract
Abstract Aqueous systems such as municipal and industrial effluents and process waters, swimming pools, and potable water supplies are clarified by immersing in the system a flocculant product comprising a high molecular weight, water soluble, synthetic organic polyelectrolyte flocculating material which has been treated with a water soluble, organic polyhydroxy compound so as to convert the polyelectrolyte material to a rubbery, selfsupporting mass. The flocculant product can be produced in dosage unit form in accordance with the amount of flocculating material required for treatment of an aqueous system. A support member such as a meshwork envelope may be used to support the flocculant product in the aqueous system. Typical polyhydroxy compounds are glycerine, ethylene glycol, propylene glycol, sorbitol and sucrose.
