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

At present, the used sludge conditioning method is mainly referred to chemical conditioning of which flocculation is the most commonly used method. It can lead to the sludge agglomeration and cluster, reduce sludge SRF, and further improve sludge dewatering performance, which facilitates subsequent deep disposal and resource utilization (Chang et al. 2001 ; Gao 2011 ; Zheng et al. 2019 ).

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]

Polyacrylamide in Agriculture and Environmental Land Management

Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation©induced erosion and enhance infiltration. Its soil stabilizing and flocculating properties improve runoff water quality by reducing sediments, N, dissolved reactive phosphorus (DRP) and total P, chemical oxygen demand (COD), pesticides, weed seeds, and microorganisms

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
