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.

Treatment of polyacrylamide production wastewater by multistage contact reactor with activated and anammox sludge - ScienceDirect

PAM wastewater is varying and complex with different types PAM contained therein, including cationic PAM, anionic PAM, amphoteric PAM and non-ionic PAM. Furthermore, the production material (ammonia hydroxide) and excess mid products (such as AM, ammonium sulfate and ammonium nitrate) also increase the NH 4 -N concentration.

Acrylamide in Environmental Water: A Review on Sources, Exposure, and Public Health Risks | Exposure and Health - Springer

Acrylamide and polyacrylamide (PAM) are used in diverse industrial processes, mainly the production of plastics, dyes, and paper, in the treatment of drinking water, wastewater, and sewage. Besides inorganic form, acrylamide is formed naturally in certain starchy foods that were heated to cook a temperature above 120 ¡ãC for elongated time. Researches in rats have demonstrated that acrylamide

degradation of polyacrylamide (pam) and methane production by mesophilic and thermophilic anaerobic digestion: effect of temperature

Degradation of Polyacrylamide (PAM) and methane production by mesophilic and thermophilic anaerobic digestion: Effect of temperature

Polyacrylamide (PAM) is generally employed in wastewater treatment processes such as sludge dewatering and therefore exists in the sludge. Furthermore, it degrades slowly and can deteriorate methane yield during anaerobic digestion (AD). The impact or fate of PAM in AD under thermophilic conditions is still unclear. This study mainly focuses on PAM degradation and enhanced methane production

3.3.2. Characteristics of slime water. The main characteristics of slime water were as follows: high concentration, high content of fine particles, high ash content, many negative charges on the surface of particles. These particles kept stable dispersion in the water due to the repulsion of the homoelectric charge.
