Zwitter-Ion Polyacrylamide for Water Treatment

I.Property of product
Zwitter-ion polyacrylamide is a type of water-soluble macromolecular polyelectrolyte and is easily soluble in water and insoluble in ethyl alcohol, acetone and other organic solvents. Its molecular chain has cationic groups and anionic groups simultaneously and can lead to charge neutralization with the active adsorption groups in sludge or sewage, absorb bridging and wind and wrap molecules. It can effectively lower neutral ζ electric potential, enable the suspended solids to subside or float. The product has excellent dehydration property and is highly effective in removal of metal ions. With wide range of PH value, it has come into extensive use.
