design of poly aluminium chloride white poly aluminium
Synthesis of a cationic polyacrylamide by a photocatalytic surface-initiated method and evaluation of its flocculation and dewatering performance: nano-TiO 2 as a photo initiator Y. Liu, H. Zheng, Y. Wang, X. Zheng, M. Wang, J. Ren and C. Zhao,
Cationic polyacrylamide is effective flocculants over a wide range of PH and nontoxic. They could be specially used for the wastewater with negative charges. Cationic polyelectrolyte water treatment is really an effective and cost-saving way.
