ABSTRACT:
Amine polymers are used to dewater suspensions of particulate matter in water. The polymers are synthesized by the reaction of a nitrile polymer such as polyacrylonitrile, an aminating agent, and a sulfur activator. The dewatering properties of these amine polymers can be beneficially employed to treat sewage sludge, silt laden water, industrial waste and the like.
