water soluble polymer flocculants synthesis
they are used to flocculate positively charged particles in many industrial units, such as municipal wastewaters and sludge dewatering. 34 acrylic acid (aa) is a commonly used anionic monomer, and anionic derivatives of polyacrylamide can also be obtained by post-polymerization hydrolysis with an alkali such as naoh to create carboxyl groups on

- What is nonionic polyacrylamide (NPAM)?
- Nonionic Polyacrylamide (NPAM): NPAM is a high-molecular-weight polymer or polyelectrolyte with polar groups that enable it to adsorb suspended solid particles in water, forming larger flocs. It accelerates particle settling in suspensions, resulting in improved solution clarity and enhanced filtration.
- What are the different types of polyacrylamide (PAM)?
- Polyacrylamide (PAM) is a kind of linear water-soluble polymer, which is the most commonly used water treatment agent in our sewage treatment! In our practical application, PAM can be divided into cationic, anionic and non-ionic three types. How to choose these three types of PAM, we should start from the differences! Structural differences
- Is non ionic polyacrylamide a water soluble polymer?
- Non-ionic polyacrylamide is a water-soluble high molecular polymer or polyelectrolyte. The characteristics of nonionic polyacrylamide PAM can be simply divided into the following three points: It has relatively good water solubility and can be completely dissolved even in cold water.
- What is polyacrylamide (PAM) used for?
- High molecular weight polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, a soil conditioner, and a viscosity improver and friction reducer in enhanced oil recovery and high-volume hydraulic fracturing.
