Abstract:
A process for dewatering of sludge, wherein said sludge comprises solids and water, comprising the steps of:a) adding a cationic dispersion polymer and a microparticle to said sludge, wherein said cationic dispersion polymer is added to said sludge simultaneous with the addition of said microparticle; and b) physically separating said solids from said water; wherein said sludge is divided into two separate streams by moving it through a pipe with a center baffle, and wherein said cationic dispersion polymer is added to said sludge on one side of said baffle and said microparticle is added to said sludge on the other side of said baffle and after both said cationic dispersion polymer and said microparticle are simultaneously added to said sludge, the two separate sludge streams are rejoined into one streams.
