Praestol A 3040 LTR is an anionic, medium charge density, high molecular weight, polymeric flocculant, which is designed to function in industrial treatment programs as a coagulant aid, or flocculant, in clarification, thickening, and sludge dewatering processes. It produces a fast-settling floc, which reduces carryover when used as a flocculant with inorganic or cationic polymeric coagulants
