Verfahren zur Abtrennung suspendierter Feststoffe aus waessrigen Systemen mit kolloidalen Flockungsmitteln

DE 102005009808 A1 UPAB: 20061002 NOVELTY - Separating suspended solids (A) from aqueous media comprises treatment with a flocculating agent (B) made of polymeric colloidal particles (C) that have a cationic surface charge, then separating flocculated matter from the medium. USE - The method is used to flocculate particles in slurries from microelectronics and waste waters from the pharmaceutical, food and textile industries (claimed). ADVANTAGE - The agent (B) can flocculate suspended particles over a wide 'flocculation window' and it solves the problems of separation of dilute or fine suspended solids, and of suspensions with a high proportion of imputities and very broad particle size distribution
