Tests of Water and Oil-Based Anionic Polyacrylamide Toxicity

Rachel Brown Abstract Anionic polyacrylamide (PAM) is effective at reducing sediment movement by flocculating particles together, which is important in maintaining water quality and erosion control. There are different formulations of PAM, including water and oil-based PAM.

A comparison study between bioflocculants and PAM for

For serpentine, PAM showed a higher flocculating capability than other tested biopolymers (Fig. 3 b). The adsorption mechanism could be a combination of electrostatic attraction between anionic PAM and positively charged Mg basal plane of serpentine and the formation of hydrogen bondings.

The surfactants used were namely anionic sodium dodecyl sulphate (SDS), cationic cetyl trimethyl ammonium bromide (CTAB) and non-ionic TritonX 100, which is a polyoxyethylenic ether compound. The unflocculated kaolin has a very slow settling rate of about 0.03 cm/s and can be improved by more than ten times using PAM-C as a flocculating agent.

Transfer and degradation of polyacrylamide-based flocculants

Flocculants are widely used in several industrial fields (mineral extraction, chemical industry, food processing industry, treatment of drinking water, etc.) to enhance solid/liquid separation in water containing suspended matter (Heath et al. 2006, Harford et al. 2011 ).

Biologia Futura: treatment of wastewater and water using

A tannin-based coagulant was used, along with anionic and cationic polyacrylamide (PAM) as a flocculant. At a pH of 5, flocculation time of 3 min, and a sedimentation time of 10 min, an experiment with a coagulant dosage of 100 mg L ?1 and 1 mg L ?1 anionic PAM (APAM) resulted in the highest color removal (81.8%). The use of a tannin-based ...

wastewater treatment using plant-derived bioflocculants

Wastewater treatment using plant-derived bioflocculants

Polygalacturonic acid interacts with anionic or cationic pollutants through its long anionic chain, which includes carboxyl (¨CCOOH), carbonyl (¨CC = O), and hydroxyl (¨COH) classes. As a result, the mechanism of flocculation is deprotonation of the OH group, which increases anionic pollutant adsorption and causes agglomeration.
