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

After flocculation treatment, production wastewater was added into a 500 L influent storage tank and the pH was adjusted to 7.3 ¡À 0.5 using a 30% sulfuric acid solution. The main composition of the wastewater was (NH 4) 2 SO 4, AM, cationic PAM, anionic PAM, amphoteric PAM, non-ionic PAM of different molecular weights, sanitary wastewater in factory and some other organic matters (COD cr 1200 ...

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

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.

polyacrylamide - wikipedia

Polyacrylamide - Wikipedia

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.
