The cationic polyacrylamide (CPAM) is commonly used as a flocculant in the water treatment process in industries of mining, metallurgy, textile, papermaking and so on. It is also a multipurpose chemical used in oil industry.

The anionic polyacrylamide (APAM) is a frequently used flocculant in treatment of various industrial wastewaters, including those from electroplating factory, metallurgic plant, steelwork and coal plant.

The nonionic polyacrylamide (NPAM) exhibits neutral nonionic properties in the aqueous solution which is hardly influenced by the PH value in the application. It is suitable for use as a settlement aid in many different mineral-processing applications
