VERFAHREN ZUR ABTRENNUNG VON FESTSTOFFEN AUS FLUESSIGKEITEN UNTER VERWENDUNG EINES KREUZSTROMABSCHEIDERS UND VORRICHTUNG ZUR DURCHFUEHRUNG DES VERFAHRENS.

摘要

The separation of solid particles from liquids or of immiscible liquids of different density is based on a cross flow separator preceded by the addition of a flocculant. The liquid has a min. residence time of 2-3 minutes and its velocity in the holes of the distributor wall is 20-30mm/s. After leaving the stack of plates it enters the outflow chamber through a perforated plate in which the velocity is 40-50 mm/s. In the inflow chamber, 80% of the particles are separated and 20% in the stack of plates.
