Pulp, paste and putty thickeners and flocculants for high

Stable feed, flocculation and hence discharge flow are essential to maintaining reliable operation of all thickeners. Control systems must allow for steady bed levels which in turn demand reliable high performance flocculation (Shoenbrunn, Hale and Bedell, 2002).
