What are the different types of polyacrylamide (PAM)?

YASA ET is supplier of three different kinds of PAM: non-ion polyacrylamide (NPAM), cationic polyacrylamide (CPAM), and anionic polyacrylamide (APAM). Click here to learn more. PAM chemical compounds are used to flocculate and coagulate suspended solids in water, wastewater, and soil.

Are cationic polyacrylamide copolymers harmful to the environment?

Cationic polyacrylamide copolymers (PAMs) are mainly applied for sludge dewatering in municipal wastewater treatment and might enter the environment by spreading the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils.

What is cationic polyacrylamide (CPAM)?

2. Cationic polyacrylamide (CPAM) This type of polymer has molecules that carry positive charge. Cationic PAM can pick up negatively charged particles (organic materials like carbon or human waste). CPAM is very efficient in usage and has high dehydration rate.

What is anionic polyacrylamide (Apam)?

Anionic polyacrylamide (Anionic PAM, APAM) Structure and properties: Anionic PAM is a water-soluble polymer. By introducing these anionic groups on the polymer backbone, APAM can react with positively charged substances. It is mainly used for flocculation, sedimentation and clarification of various industrial wastewaters.

What is nonionic polyacrylamide?

3. Nonionic Polyacrylamide (Nonionic PAM, NPAM) Structure and Properties: Nonionic PAM is a high molecular polymer or polyelectrolyte with a certain amount of polar genes in its molecular chain.

Is cationic polyacrylamide soluble in water?

Cationic polyacrylamide (CPAM) is highly soluble in water and can form clear solutions at low concentrations.Due to the positively charged functional groups, Cationic polyacrylamide (CPAM) can attract and bond with negatively charged particles and suspended solids in water, leading to flocculation and sedimentation.
