TP226 Overview of the effects of residual flocculants on aquatic receiving environments

The ecotoxicological and environmental risk of releases of residual coagulants and flocculants is reviewed. Two broad groups of flocculants are considered. These are polyelectrolytes and inorganic aluminium salts.

Acute toxicity of polyacrylamide flocculants to early life stages of freshwater mussels - Buczek - 2017 - Environmental Toxicology and Chemistry

Polyacrylamide has become an effective tool for reducing construction-related suspended sediment and turbidity, which are considered to have significant adverse impacts on aquatic ecosystems and are a leading cause of the degradation of North American streams and rivers.

The effect of residual flocculants in the circulating water on dewatering of Gol-e-Gohar iron ore

Among the flocculants, the anionic one demonstrated desirable settling efficiency due to its strong hydrogen bonding property and large flocs formed through repulsive force between the flocculant and particle surfaces.

The expanding production and widespread application of acrylamide caused inevitable release to aquatic ecosystems. Contrary to its extensive attention to human and animal health, the hazards of acrylamide to the aquatic primary productivity have been rarely studied. The potential effects of acrylamide on the marine algae (Nitzschia closterium) and the limnetic algae (Scenedesmus quadricauda

Effect of Flocculants Residue on Rheological Properties of Ultra-Fine Argillaceous Backfilling Slurry - PMC - National Center for Biotechnology

In this study, to explore the effect of flocculants residue on the rheological properties of the slurry, a series of rheological tests (constant shear rate test and variable shear rate test) were performed by changing the type, dosage, stirring time, temperature of flocculants addition and the amount of binder added.

Protein-folding-inspired approach for UF fouling mitigation using elevated membrane cleaning temperature and residual hydrophobic-modified

The accumulation of residual flocculants (especially those with high molecular weight (MW) (He et al., 2021 )), as well as micro-flocs, on the membrane may induce or aggravate fouling, leading to unavoidable flux decline and increased operating cost ( Xu et al., 2021 ).

Challenges and Opportunities of Biocoagulant/Bioflocculant Application for Drinking Water and Wastewater Treatment and Its Potential for Sludge

Chemical coagulation and flocculation are processes that are highly dependent on pH changes because the latter has the ability to determine the species of polymeric polymer that will form when metal-based coagulants/flocculants dissolve in water [ ]. The specific operational pH needs to be analyzed for each coagulant type.
