- What is Pam used for in water treatment?
- PAM is also widely used as a flocculant in drinking water treatment (at concentrations <1 mg/L). 37 PAM can create bridges between destabilized particles, forming micron-size aggregates with good settling properties. 38 Cationic, nonionic, and anionic PAM have all been studied for flocculation.
- Why is polyacrylamide used in water treatment?
- With the increasing global water scarcity and escalating environmental pollution, efficient water treatment has become paramount. Polyacrylamide, as a versatile polymer compound, has demonstrated significant achievements in the field of water treatment. PAM is widely used as a coagulant and flocculant in wastewater treatment.
- What is nonionic polyacrylamide PAM?
- Nonionic polyacrylamide PAM is mainly used for flocculation and sedimentation of various industrial wastewater, and clarification and disposal of precipitation. Many friends have little knowledge of this type of polyacrylamide. Today, I will introduce the characteristics, efficacy, and usage of nonionic polyacrylamide PAM.
- What is cationic polyacrylamide (CPAM)?
- Cationic Polyacrylamide (CPAM): CPAM is a linear high-molecular-weight compound known for its affinity and adsorption capabilities due to its active functional groups. It is primarily used for coagulating colloids with negative charges.
