Abstract:Coagulation-flocculation is one of the important methods in water and wastewater treatment, and sludge dewatering. According to different principles, the inorganic-organic hybrid materials used in coagulant/flocculant can be prepared by means of hydrolysis-prepolymerization, physical co-mixing, chemical(graft) copolymerization or cross-linking, and the methods of preparation and characterization are reviewed. Many new and high efficient flocculants are successfully prepared, but most of them are only in the labs. |
Key words:composite flocculants; hybrid materials; water and wastewater treatment |
