preparation of a novel cationic starch bioflocculant and its application performance in municipal sewage odor mitigation and sludge

Preparation of a Novel Cationic Starch Bioflocculant and Its Application Performance in Municipal Sewage Odor Mitigation and Sludge

The supernatant fluid and sludge produced by traditional polyacrylamide flocculant (PAM) flocculation of municipal sewage emit a strong odor, and the dewatering performance of flocculant flocculating sludge based on acrylamide as the main synthetic raw material remains undesirable. In this study, we investigated a new green bioflocculant called SDF. This bioflocculant was made using 3-chloro-2

Cationic polyacrylamide copolymers (PAMs): environmental half life determination in sludge-treated soil | Environmental Sciences Europe

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.

Research on a new cationic polyacrylamide (CPAM) with a cationic microblock structure and its enhanced effect on sludge condition

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. Therefore, it is particularly important to develop new and efficient flocculants

Determination of polyacrylamide based flocculants in sewage sludge by off-line thermochemolysis-GC¨CMS analysis | Discover Water - Springer

This study aimed to develop an offline thermochemolysis method for the determination of cationic polyacrylamide (cPAA) flocculants in environmental samples, using trimethylanilline hydroxide as a thermochemolytic agent. This method induces degradation of cPAA into defined substituted glutarimide derivates, as specific pyrolysis products. These pyrolysis products appeared in typical pattern of

Effects of Cationic Polyacrylamide Characteristics on Sewage Sludge Dewatering and Moisture Evaporation - PLOS

The effects of the molecular weight (MW) and charge density (CD) of cationic polyacrylamide (CPAM) on sludge dewatering and moisture evaporation were investigated in this study. Results indicated that in sludge conditioning, the optimum dosages were 10, 6, 6, 4, and 4 mg g?1 CPAM with 5 million MW and 20% CD, 5 million MW and 40% CD, 3 million MW and 40% CD, 8 million MW and 40% CD, and 5
