Polyacrylamide
Polyacrylamide (PAM), a kind of water-soluble high flocculant polymer and mainly used in the drinking water purification and clarification purposes, paper-making, metallurgical, textile,sugar refing clarification of industrial wastewater in various industries . Such as the steelworks, metallurgy, coal washing, sludge, electroplate factories.
There have 4 categories of Anionic, Cationic, Non-ionic and Amphoteric type.

Application:
1. Anionic PAM mainly used in minerals selection, metallurgy, coal washing, food, steel, spinning and papermaking industry which involves separation of solid-liquid and waste water treatment. Anionic PAM also can be used for oil well and oil extraction in oil industry, and retention aids and intensifier in papermaking industry.
2. Cationic PAM is used as flocculants and dewatering reagents for industry waste water and sewage; retention aids and intensifier in paper making industry; waste water treatment in pharmaceutical, leather making, printing and dyeing industry waste water treatment, and organizer in textile industry.
3. Nonionic PAM is used as flocculants with high selectivity in oil well fluid,and acidic waste water treatment.
4. Amphoteric PAM is mainly used high difficult waste water treatment and sludge dewatering reagents in oil refining and chemical industry or paper making industry.
