Polyacrylamide Anionic (PAMA)

Main application: Use PAMA of different molecular weight according to different purposes.

  1. Treatment of industrial waste water, especially for water contain thick , high concentration of cationic granules, and the PH being neutral or basic, e.g. waste water from steel plant, electroplating plant, refinery plant or coalwash plant.
  2. Tap water treatment. Many waterworks use river as water source in China which contain large amount of dirt and mineral substances. The water is often turbid even after sedimentation and filtration. normally inorganic flocculants are used, which is not effective as well and may cause large amount of mud. PAMA is maybe 10 times more effective and the addition is only 2% of that of inorganic flocculants. The PAMA we provide contains <0.05% of monomer. It is suitable for the water treatment, especially water resources contaminated with organic substances.
  3. PAMC is an effective way for the recover of starch or lees in starch or alcohol making. Many starch factory lose a considerable amount of starch in the waste water. The starch can be sedimented by adding PAMC, then the precipitate is collected and filtered under pressure. The filer cake is rich in starch and can be a good feed. In the same manner, lees is recovered. An alcohol factory in Heilongjiang Province, which is the largest in asia, used PAMC to recover lees and achieved good benefit.
  4. PAMA can be used as profile control agent or water shut-off agent in oil drilling.
  5. PAMA has a variety of usage in papermaking. It a good strengthing agent or dispersant for long fibre paper. It can also be flocculant, retention and filtration agent in waste water treatment.
