AMINPOLYMERE MED AFVANDINGSVIRKNING FREMGANGSMAADE TIL FREMSTILLING HERAF OG FREMGANGSMAADE TIL BEHANDLING AF ET VANDIGT SYSTEM HERMED

摘要

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.
