Solid Liquid Separation includes important industrial processes used for recovery and processing of solids or purification of liquids. Most of the process industries in which particulate slurries are handled use some form of solid-liquid separation and yet the subject is not adequately covered in most higher education courses.

A new cation-modified Al-polyacrylamide (CAPAM) flocculant was prepared by the in situ polymerization of acrylamide (AM) and (2-methacryloyloxyethyl) trimethyl ammonium chloride (DMC) with Al(OH)3 sol. The optimum preparation conditions were obtained by a one-factor experimental design: as the amount of AlCl3 was fixed at 0.025 mol, the polymerization time, polymerization temperature, n(AM ...

Flocculant - an overview | ScienceDirect Topics

Flocculants are agents that make fine and subfine solids or colloids suspended in the solution form large loose flocs through bridging (Fig. 9.4), thus achieving solid-liquid separation. The most commonly used flocculants for soil conditioning are polyacrylamide, carboxymethyl cellulose (CMC), and polyanionic cellulose (PAC).

What is polyacrylamide used for?

Polyacrylamides (PAM) are an important class of water-soluble polymers with low synthetic cost, high viscosity, and good rheological properties. PAM is widely used for oil and gas extraction and wastewater treatment industries, especially in drilling fluids, fracturing fluids, polymer drives and other oil and gas extraction fields.

Are polyacrylamides water soluble?

Discover the latest articles, news and stories from top researchers in related subjects. Polyacrylamides (PAM) are an important class of water-soluble polymers with low synthetic cost, high viscosity, and good rheological properties.

What is cationic polyacrylamide (CPAM)?

Cationic polyacrylamide (CPAM) is one of the most frequently used flocculants with high intrinsic viscosity and charge density. This flocculant is a water-soluble acrylamide-based polymer having cationic quaternary ammonium groups .

How cationic polyacrylamide (PAMC) is prepared?

Flocculation and mechanism was discussed based on zeta potential and pH analysis. A novel cationic polyacrylamide (PAMC) with various cationic monomer contents were prepared by copolymerizing acrylamide (AM) and methacryloxyethyl trimethyl ammonium chloride aqueous solution (DMC) through low-pressure ultraviolet (UV) initiation.

Is acrylamide a cationic flocculant?

The copolymer of acrylamide (AM) and DMC is used as an effective cationic flocculant in wastewater treatment. A series of copolymers of AM and DMC (PAMC) were synthesized using different approaches. In earlier studies, γ-ray irradiation with inverse emulsion polymerization was employed to copolymerize AM and DMC .

Can cationic polyacrylamide be used for oily wastewater treatment?
