Experimental analysis of centrifugal dewatering process of polyelectrolyte flocculated waste activated sludge

摘要

The study experimentally investigated the centrifugal separation of moisture from acivated sludge subject to cationic polyelectrolyte flocculation. An arm-suspended centrifuge was employed which allowed in-situ detection on all positions of interfaces of centrifuged sludge as functions of time. Experimental results revealed that, sludge flocculation would yield a significant sedimentation effect at the First phase of centrifugation.
