What is the application of the polyacrylamide PHPA?

Polyacrylamide (PHPA) is the water soluble polymer, it is one of varieties a water-soluble polymer compounds wide application, PHPA and its ramification can be used as efficient flocculant, thickening agent, paper strengthening agent and liquid drag reduction agent, which is widely used in water treatment, paper, petroleum, coal, mining, metallurgy, geology, textile, construction and other industrial sectors.

PHPA has two grade product are CPAM and APAM:
Cationic (CPAM) polyacrylamide uses: as a flocculant in wastewater treatment for mining, metallurgy, textile, paper and other industries. In the petroleum industry for a variety of jobs.
Anion (APAM) polyacrylamide application: In the industrial wastewater (electroplating wastewater, metallurgical wastewater, wastewater from iron and steel plant, coal washing waste water, etc.) flocculent in precipitation.
