Natural organic matter removal by coagulation during drinking water treatment: A review
TLDR
Most of the NOM can be removed by coagulation, although, the hydrophobic fraction and high molar mass compounds of NOM are removed more efficiently than hydrophilic fraction and the low molarmass compounds.About:

The impact of alum coagulation on pharmaceutically active compounds, endocrine disrupting compounds and natural organic matter
TL;DR: In this article, the impact of chemical coagulation using alum on the removal of three endocrine-disrupting compounds (EDCs; bisphenol A, clofibric acid and estriol) and nine pharmaceutically active compounds (PhACs; acetaminophen, carbamazepine, diclofenac, gemfibrozil, ketoprofen, naproxen, pentoxifylline, sulfamethoxazole and sulfachloropyridazine).

Coagulation behaviors of new covalently bound hybrid coagulants (CBHyC) in surface water treatment
Si Chen,Si Chen,Ziwen Yuan,Ziwen Yuan,David Hanigan,Paul Westerhoff,Hua-Zhang Zhao,Hua-Zhang Zhao,Jinren Ni,Jinren Ni +9 more
TL;DR: In this article, the performance of a covalently-bound hybrid coagulant (CBHyC) in natural surface water coagulation using jar test was systematically evaluated, and the CBHyC formulation with higher zeta potential achieved better removal of natural organic matter (NOM) and resulted in less of a pH change.
Journal ArticleDOI
Harvesting of marine microalgae using cationic cellulose nanocrystals
TL;DR: Cationic CNCs can serve as a sustainable alternative natural flocculant for harvesting both freshwater and marine micro algae, and compared its performance to chitosan.
Journal Article
Performance of granular activated carbon/nanoscale zero-valent iron for removal of humic substances from aqueous solution based on Experimental Design and Response Surface Modeling
TL;DR: In this article, the effect of independent variables responsible for higher adsorption of humic substances by activated carbon supported nanoscale zerovalent iron from aqueous solutions was examined.

Coagulation by hydrolysing metal salts
Jinming Duan,John Gregory +1 more
TL;DR: In this paper, a detailed understanding of the sweep flocculation mechanism is provided, especially with regard to the role of charge neutralization and hydroxide precipitation. But the results can be reasonably well explained in terms of established ideas, and there are also some uncertainties regarding the action of pre-hydrolysed coagulants.

Organic polyelectrolytes in water treatment.
Brian Bolto,John Gregory +1 more
TL;DR: There is a focus on polymers for primary coagulation, their use as coagulant aids, in the recycling of filter backwash waters, and in sludge thickening.
Journal ArticleDOI
Fundamentals, present and future perspectives of electrocoagulation.
TL;DR: This paper presents an in-depth discussion and consideration of the factors that need to be addressed for optimum performance of this technology.
