Research on a new cationic polyacrylamide (CPAM) with a cationic

Abstract Flocculation is one of the commonly used sludge conditioning methods in water supply plants, which can improve the sludge dewatering performance by reducing the specific resistance of sludge (SRF), decreasing the amount of sludge, and finally lowering the transportation cost and subsequent disposal cost of sludge.

Cationic polyacrylamide copolymers (PAMs): environmental half life

Abstract Background 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.

Abstract A series of hydrophobic cationic monomers were introduced into acrylamide chain to form hydrophobically modified cationic polyacrylamide. The hydrophobic cationic monomer used in this study was 3-acrylamido-2-hydroxypropyltrialkylammonium chloride (AHPTAAC) in which the alkyl groups were hexyl, octyl and dodecyl groups.

The reduction in the negative zeta potential was found to be considerably greater in the presence of cationic polyacrylamide than anionic and amphoteric polyacrylamide, due to an increased adsorbed layer thickness of cationic polyacrylamide. 208 Amphoteric polymers exhibit both cationic and anionic behaviors, and their strength and a relative number of sites vary depending on surface charge

The use of modified cationic polyacrylamides as strength resins in papermaking is well known [66]. The preparation of a useful product consists of the reaction of a cationic polyacrylamide with the dialdehyde glyoxal and was first reported in 1971 [67]. Strength resins generally come in a solution form.

Additionally, it is of great significance to reduce the cost of subsequent treatment and prevent environmental pollution (Zhou et al., 2017; Wang et al., 2013). Among various chemical conditioners, cationic polyacrylamide (CPAM) is widely used in sludge treatment plants due to its advantages of fast treatment rate and wide application range.

Optimizing the Flocculation Effect of Cationic Polyacrylamide Prepared

Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM. In this paper, the optimal flocculation conditions of a novel CPAM were
