Coagulation/flocculation in dewatering of sludge: A review

In comprehensive consideration of dewatering rates, MC of sludge cake, and equipment costs, polymeric flocculants exhibit good dewatering performance due to their larger floc size and more void spaces for water drainage (Lo et al., 2001; Novak and O'Brien, 1975). PAM and its derivatives are the most commonly used organic polymeric conditioners in sludge dewatering.

Polymers / Flocculants | Aulick Chemical

Polymers / Flocculants. Polymeric chemistry has great effects on the performance of a wastewater facility - performance being the key word. Sludge dewatering polymers must perform well for the wastewater treatment facility to perform well. The purpose of polymers is to condition sludge by removing water with mechanical equipment such as belt filter presses, centrifuges, gravity belt thickeners and dissolved air floatation units.

Most flocculants in use today are synthetic water soluble polymers based on acrylamide and its derivatives and which may include either anionic or cationic groups in a wide range of molecular weights and charge densities. They are supplied as dry powders or in liquid form as liquid dispersions up to 50 percent active, emulsions up to 40 percent and in some cases as low concentration solutions.
