First, sewage treatment

In sewage treatment, anionic PAM can be used for flocculation and sedimentation to purify sewage. In this type of wastewater treatment, the use of cationic PAM can increase the use of water reuse cycles.

Second, industrial water treatment

In industrial water treatment, PAM is mainly used as a formula.

Third, raw water treatment

In raw water treatment, PAM anion is used in combination with activated carbon and the like, and can be used for coagulation and clarification of suspended particles in domestic water. In the raw water treatment, the organic flocculant anion PAMPAM is used instead of the inorganic flocculant, and the water purification capacity can be increased by more than 20% even if the sedimentation tank is not modified.

Therefore, many large and medium-sized cities currently use PAM as a supplement when water supply is tight or water quality is poor.
