Anionic Polyacrylamide, Water Treatment Chemical
It is the white powder. The APAM with the molecular weight of 6-22 million has good water solubility, and it can be dissolved in water by arbitrary proportion but not in organic solvents. It has the characteristics of high-polymer electrolyte in the neutral and alkaline medium, and it is sensitive to the electrolyte salt. And it can be cross-linked into insoluble gel with the high valence metal ions.

Cationic polyacrylamide is a white granule and it is a linear high molecular compound which is soluble in water. It is nontoxic, odorless and hygroscopic. Its outstanding feature is the high hydrophilicity which enables it dissolves in water at any ratio while insolubilizes in organic solvents like ethanol and acetone. The active group with positive charge on the molecular chain has excellent effect of flocculation. Different models of products can be chosen according to the properties of sludge. This product can clarify the solution and separate the solid and liquid rapidly by absorbing the solid particles suspending in sewage which can make the particles agglomerate into large flocculate through bridging between particles or charge neutralization. Therefore, this product has a low application dosage, high level of dehydration efficiency and low level of water content in sludge.
