hydrothermal pretreatment of sewage sludge enhanced the anaerobic degradation of cationic polyacrylamide (cpam)

Hydrothermal pretreatment of sewage sludge enhanced the anaerobic degradation of cationic polyacrylamide (cPAM)

Cationic polyacrylamide (cPAM) is very effective at flocculating negatively charged solids suspending in wastewater (Haveroen et al., 2005). Typical cPAM level in SS is in the range of 2.5-10 mg/g total solid (TS) ( Wang et al., 2018 ).

Due to its dense positive charges in this new cationic microblock structure, it greatly improved the functions of electric neutralization, electrical patching, and adsorption bridging. The cationic fragment structure in the template copolymer could help to generate large and dense floc structure and form stable drainage channels.

The investigation of the specific behavior of a cationic block structure and its excellent flocculation performance in high

Cationic polyacrylamide (CPAM) has been developed and widely used for the separation and treatment of high-turbidity water because of its satisfactory solid-water separation performance and the negative charge properties of most high-turbidity wastewater. 6,7 Negatively charged particles can be thoroughly neutralized and destabilized by the cati...

characterization and evaluation of dewatering properties of padb, a highly efficient cationic flocculant

Characterization and Evaluation of Dewatering Properties of PADB, a Highly Efficient Cationic Flocculant

PADB was a highly efficient cationic flocculant, which was synthesized through the copolymerization of acrylamide (AM), acryloyloxyethyl trimethyl ammonium chloride (DAC), and butylacrylate (BA) with ultraviolet initiation by micellar polymerization technology. The PADB was the terpolymer of AM, DAC, and BA.
