  • Polyacrylamide in Water Treatment - Sinofloc

    Polyacrylamide in Water Treatment. Testing is always applied before formal using polyacrylamide in wastewater treatment. If the amount is too low, the product does not work, and if the amount is too high, there will be opposite reaction. The reason is when more than a certain concentration, polyacrylamide can not only have flocculation effect ...

  • Super Water-Absorbing Polymers

    The polymer absorbs water within a few seconds to form slush. Due to its rapid and large water-absorbency (and its harmlessness), sodium polyacrylate is used as the absorbent material in diapers. Polyacrylamide consists of repeating units of the monomer –CH 2 CH(CONH 2)–. The nitrogen forms hydrogen bonds with water molecules.
