Cationic polyacrylamide copolymers (PAMs): environmental half life

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.

Biopolymer-based flocculants: a review of recent technologies

The treatment efficiency was better than polyacrylamide and cationic polyacrylamide (Wang et al. 2016a). In another study, the chitosan-g-DMDAAC was used in the dewatering of anaerobically digested sludge. Within the optimal dosage, the CMC was 81.7%, SRF was 2.64 ¡Á 10 8 m/kg, and CST was 1.31 s¡¤L¡¤g ?1 (Zhang et al. 2019). In the pH range

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

The cationic monomers on these microblock segments can be polymerized to form a CPAMD with a new cationic microblock structure. In addition, microwave has mechanical effects such as oscillation, emulsification, and diffusion, which can accelerate the heat and mass transfer process of the reaction system, thus accelerating the reaction rate (Wiesbrock et al. 2004; Hoogenboom and Schubert 2007

polyacrylamide

Polyacrylamide

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Physicochemical properties [ edit]

Spotlight on the Life Cycle of Acrylamide-Based Polymers Supporting

For sludge treatments, consumption of a cationic polyacrylamide of 5.4 g¡¤kg ?1 of total solids is found to be the best economical solution . Several studies were made, following life cycle analyses, to evaluate energy consumption of wastewater treatment (e.g., Tillman et al. [ 90 ], Hospido et al. [ 91 ] and Wenzel et al. [ 92 ]).
