Abstract
Aqueous dispersions of solids are readily flocculated with polymeric anionic flocculants containing comonomers of 2-acrylamido-2-methylpropanesulfonic acid and acrylamide. The polymeric flocculant should contain from about 1.0 to about 35.0 mole percent of repeating units derived from 2-acrylamido-2-methylpropanesulfonic acid and should have a Brookfield viscosity of at least 2.0 centipoises. In addition to their flocculating ability, employment of these copolymers achieves a high degree of compaction in the flocculated solids.
