Synthetic Polyelectrolytes Based on Polyacrylamide: Non-ionic

Polyacrylamides are used in the "thickening" process of colliery effluent treatment. The wastewater contains mainly clay particles, in suspension, which are flocculated using non-ionic and anionic polyacrylamides, which have molar masses in the range of 7-15 million g/mol. The choice of flocculant to treat a given type of a

Properties of Polyacrylamides

Cationic polyacrylamides (CPAM) are used for emulsion breaking, and for promoting filtration and sludge dewatering. The primary use is waste water treatment. As a primary organic coagulant, it neutralizes negatively charged colloidal particles and thus induces flocculation and sedimentation which reduces sludge volume. In paper mills, it is
