ABSTRACT:
An aqueous organic or inorganic suspension can be coagulated and then flocculated by flowing it past a shaped body comprising a mixture of water soluble multivalent metal coagulant and a water soluble organic polymeric flocculant in the form of substantially discrete particles. The surface of the shaped body is eroded by the flowing stream to form a solution of the coagulant in which the polymeric flocculant particles are entrained, and these subsequently dissolve into the suspension.
