Title: Staged flocculation followed by thickening and dewatering of flotation tailings and uncleaned sludges

Abstract

A multistage flocculation process using either polyacrylamide (PAA) or polyethylene oxide, for the removal or recovery of solids from sludges and coal washings is described. Optimization number of flocculation stages must be determined experimentally and depends upon intial solids concentration charge rate, hydrocyclone diameter, agitation speeds and the consumption rate of the flocculation agent.
