What Are the Functions and Uses of Nonionic Polyacrylamide?

(1) Sewage treatment agent When the suspended sewage is acidic, it is more appropriate to use nonionic polyacrylamide as the flocculant. At this time, PAM plays a role of adsorption and bridging, flocculating and sedimenting the suspended particles to achieve the purpose of purifying sewage.

Difference and application of cationic, anionic and nonionic PAM

Sewage treatment agent: when the suspended sewage is acidic, it is more suitable to use nonionic polyacrylamide as flocculant. PAM plays an important role in bridging adsorption, which makes suspended particles produce flocculation and sedimentation, and achieves the purpose of purifying sewage.

High-Temperature-Resistant, Low-Concentration Water-Controlling

The composite cross-linking agent can cross-link low concentrations of polyacrylamide to obtain a high-temperature-resistant weak gel system in oilfield sewage. By adjusting the ratio of Cr(III), phenolic resin, and polyacrylamide, an optimum formula MF-7 can be obtained according to the gel strength.

Polymers for Coagulation and Flocculation in Water Treatment

Non-ionic polyacrylamide is a good example of the synthetic non-ionic polyelectrolytes while examples of natural non-ionic polysaccharides include amylose, amylopectin, cellulose, guar gum, etc. Natural, non-ionic polysaccharides that have been used in the water industries include starches, galactomannans, cellulose derivatives, microbial polysaccharides, gelatins and glues.

Polyacrylamide Soil Conditioners: The Impact on

Nonionic polyacrylamide has a strong hydrophilic character, greater than other nonionic, water-soluble polymers. Despite being described as nonionic synthetic polyacrylamides obtained as a result of polymerization or copolymerization of acrylamides, often contain in their macromolecules about 1¨C3% of anionic groups [ 4 ].

Polymer flocculants tend to be used in water purification, because polymer flocculants can increase aggregates by gathering components of fine turbidity which cannot sink as it is in the wastewater and can enhance solid¨Cliquid separation from a wastewater.
