- What are the different types of polyacrylamide flocculants?
- 1. Introduction It is well known that polyacrylamide (PAM), which is a type of water-soluble polymer, is widely used in industrial wastewater treatment as a flocculant , . In general, these flocculants can be divided into three groups, depending on the nature of their charge, i.e., cationic-PAM, anionic-PAM and non-ionic-PAM.
- Which polyacrylamide has a good flocculation efficiency?
- Flocculation performance of four kinds of polyacrylamide (PAM) with different chain end group, namely, PAM, star-PAM, PGS-PAM and Al (OH) 3 -PAM hybrids, in Kaolin suspensions have been investigated by Spectrophotometer. It was found that their flocculation efficiency deceases in the order: PGS-PAM -PAM PAM.
- How much anionic Polyacrylamide can be used as a flocculant?
- Using anionic polyacrylamide as a flocculant, the dosage is 2%-5% of the non-polar flocculant, but the effect is dozens of times that of inorganic solvent. Leave your requirements in detail here (including the specifications, package, quantity, country, etc.), we will reply you quickly.
- What is cationic polyacrylamide flocculant?
- Cationic polyacrylamide is widely used for municipal sewage treatment. Its sludge dewatering qualities make it the best for sewage treatment. Cationic polyacrylamide flocculant is grouped depending on its levels of ionicity. The ionicity levels include strong, medium, and weak.
