Soil Stabilization Polymer With Anionic Polyacrylamide
Cationic polyacrylamide is mainly used as flocculants and dewatering reagents for industry waste water and sewage; retention aids and intensifier in paper making industry; waste water treatment in pharmaceutical, leather making, printing and dyeing industry waste water treatment, and organizer in textile industry.
Cationic polymer in water treatment is usually used when municipal sewage sludge is dehydrated.
Cationic polyacrylamide copolymers (PAMs): environmental
Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils.
Cationic polyacrylamide (CPAM) were used extensively in water treatment, enhanced oil recovery and sludge dewatering. The review summarized the synthesis methods research progress of cationic

Screw Press Machine Sludge Dewatering Polymer Flocculant. Description Polyacrylamide, simply called PAM, is a water-soluble flocculant polymer, available in anionic, cationic and nonionic for different Industries
Polyacrylamide degradation and its implications
PAM used as a flocculant in water treatment or sludge dewatering is disposed in high-solid biogas digestors or landfills. 94 Although PAM is typically considered to be relatively recalcitrant to
With sludge II, (Fig. 6d) the reference polymer performed better at low doses than did CNFC I, but CNFC II performed similarly to the reference polymer. Since both CNFCs displayed similar purification results, the CNFC II’s high cationic charge probably promoted flocculating anionic colloidal impurities, while CNFC I’s long, flexible
Understanding the impact of cationic polyacrylamide
1. Introduction. Biological wastewater treatment is widely used in the world, but large amounts of waste activated sludge (WAS) are produced, which is a big problem faced by wastewater treatment plants (WWTPs) nowadays (Chen et al., 2016, Wang et al., 2012, Wang et al., 2017a, Zhao et al., 2016a, Zhao et al., 2017b).WAS would readily cause secondary pollution if it is treated and disposed
When the cationic polymer attaches to the sludge solids, its charges are shielded and the polymer chains begin to recoil into the shape they formed during the polymerization process. As they coil, they bring the sludge solids closer together, excluding water which is separated from the sludge.
Cationic Polyelectrolyte Chemical Used for the Sludge
PAM - Cationic polyacrylamide Description: This product is a water-soluble high polymer.It’s not soluble in most organic solvents, with good flocculating activity, and can reduce the friction resistance between liquid. Application Field: 1. It is mainly used for the sludge dewatering and decrease the rate of water content of sludge.
Cationic polyacrylamide, is a white powder water -soluble polymer which is copolymerized by cationic monomer and acrylamide. It has the function of decolorizing, adsorbing, turbid eliminating and bonding. It generate a good flocculation and can decrease the resistance between liquids.
