Applicaton:
Anionic PAM are mainly used as flocculent to separate solid from liquid in the fields of mineral separation, metallurgy, chemicals and foodstuff; and used for waste-water processing in iron and steel, textile and paper industries; in oil industry, it is used for drilling and EOR; in chemical industry, it is used as surface activating agent.
Cationic PAM is used as flocculent and sludge dewatering agent in waste-water processing. In paper-making industry, it is used as retention aid. In textile industry, it is used as fabric conditioning agent
