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

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.

Efficient dewatering of polymer-rich aerobic granular sludge with cationic polymer containing hydrocarbons | International Journal

This study compared the dewatering properties of aerobic granular and activated sludge from full-scale wastewater treatment plants, and determined how polymer dose and type affect granular sludge dewatering efficiency. At the same dose, granular sludge filtration cake had about 4% lower humidity than activated sludge cake. Aerobic stabilization improved only activated sludge dewatering. The

Novel methodologies for determining a suitable polymer for effective sludge dewatering

Low cake solids content and high polymer demand for conditioning in sludge dewatering are two major issues that lead to high chemical and transportation costs in wastewater treatment plants (WWTPs). The selection of appropriate polymer types and optimal polymer demand (OPD) for conditioning could help to minimize chemical costs and maximize dewatering performance.

Study of sludge moisture distribution and dewatering characteristic after cationic polyacrylamide (C-PAM) conditioning - Semantic Scholar

AbstractDewatering is a key step in sludge handling, and flocculant conditioning is the commonest way to improve the sludge dewatering. The sludge dewatering performance is largely affected by the sludge moisture distribution. But changes of sludge moisture distribution by flocculants were unclear and literature findings were controversial to each other. This paper investigated the changes of

Sustainability | Free Full-Text | Metal Cation and Surfactant-Assisted Flocculation for Enhanced Dewatering of Anaerobically Digested Sludge

Flocculation and dewatering of anaerobically digested sludge is known to be a major cost factor in the economy of wastewater treatment plants. Hence, several endeavors have been underway in search of affordable and effective alternatives. This study focuses on the effects of different metal cations, including FeCl3, CaCl2 and MgSO4, on the dewaterability of digested sludge. The effects of
