Anionic Polymer Flocculant & Polyacrylamide Powder

Home Products Anionic Flocculants Anionic Flocculants SINOFLOC anionic flocculants are co-polymers of acrylamide with increasing proportions of acrylate groups, which give the polymers negative charges, and thus anionic active character, in aqueous solution. Our anionic polyacrylamide is available in solid powder and emulsion forms. Email Download

anionic polyacrylamide

ANIONIC POLYACRYLAMIDE

1 BACKGROUND Anionic polyacrylamide is the copolymer of acrylamide and acrylic acid. No studies on the environmental fate of polyacrylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biodegrade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concern to aquatic organisms.

Improvement of coagulation¨Cflocculation process using anionic polyacrylamide as coagulant aid

However, the highest reduction in the volume of sludge (42%) was obtained when anionic polyacrylamide was used as coagulant aid with ferric sulphate. As can be seen for Fig. 6 , the volume of sludge produced (600 ml l-1 ) when ferric sulphate was added fell from 600 ml l ?1 to 350 ml l ?1 when this coagulant acted together with the anionic polyacrylamide as coagulant aid.

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.

Anionic and cationic polyacrylamides make up roughly ~ 75% of the total polyacrylamide market, with nonionic products comprising the final ~ 25%. The largest application areas include solid-liquid separation in wastewater treatment (municipal and industrial), oil recovery, papermaking, mineral processing, cosmetics, and the food and beverage industries.
