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:

Contribution of amide-based coagulant polyacrylamide as precursors of haloacetamides and other disinfection by-products
TL;DR: In this article, the amide-based organic polymer coagulants polyacrylamide (PAM) and its monomer acrylamides (AM) can serve as a source of HAcAm and other DBPs including trihalomethanes (THMs) and haloacetonitriles (HANs) during chlor(am)ination.

Coagulation of humic acid and kaolin at alkaline pH: Complex mechanisms and effect of fluctuating organics and turbidity
TL;DR: In this article, a coagulation was performed on synthetic test waters prepared with different concentrations of humic acid (HA) and kaolin to simulate organics and turbidity found in natural surface waters.
Journal ArticleDOI
Distribution of dissolved organic matter fractions along several stages of a drinking water treatment plant
TL;DR: In this paper, a study was conducted to track dissolved organic carbon (DOC) through the different stages of a drinking water treatment plant that includes a conventional treatment CT (coagulation/flocculation, sedimentation and sand filtration) and two parallel advanced treatments consisting of ozonation plus activated carbon filter (AT1) and ultrafiltration (UF) and reverse osmosis (RO) (AT2), respectively.

Zeta potentials and sizes of aluminum salt precipitates – Effect of anions and organics and implications for coagulation mechanisms
TL;DR: In this paper, the zeta potential and size of aluminum hydroxide precipitates from aluminum nitrate and aluminum sulfate (alum) solutions were examined as a function of solution pH at different concentrations using laser Doppler velocimetry and dynamic light scattering techniques.

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.
Journal ArticleDOI
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.
