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:

Mitigation of Humic Acid Inhibition in Anaerobic Digestion of Cellulose by Addition of Various Salts
TL;DR: The impact of salt addition to mitigate the inhibitory effects of humic compounds was investigated and validated by inductively coupled plasma atomic emission spectroscopy analyses, which showed the binding capacity of different cations to humic acid.

Adsorption and desorption of dissolved organic matter by carbon nanotubes: Effects of solution chemistry.
Maya Engel,Benny Chefetz +1 more
TL;DR: Understanding of DOM-SWCNT interactions in aqueous systems influenced by rapid changes in salinity, and potential use of SWCNTs in water-purification technologies is enhanced, and the initial adsorption rate is dependent on solution parameters.
Journal ArticleDOI
Effect of dosing sequence and solution pH on floc properties of the compound bioflocculant-aluminum sulfate dual-coagulant in kaolin-humic acid solution treatment.
TL;DR: The compound bioflocculant (CBF)-aluminum sulfate (AS) dual-coagulant and AS were comparatively studied for the coagulation of kaolin-humic acid solution and indicated that, the flocs formed by AS-CBF showed the largest size and the best recoverability across the pH range investigated.
Journal ArticleDOI
The effect of TiO2 nanoparticles removal on drinking water quality produced by conventional treatment C/F/S
TL;DR: Investigation of the efficiency of conventional coagulation/flocculation/sedimentation (C/F/S) from drinking water treatment to remove TiO2 nanoparticles (NPs) from surface waters shows thatTiO2 NPs removal is high, and the treated water quality is not compromised.

Upgrading coagulation with hollow-fibre nanofiltration for improved organic matter removal during surface water treatment.
Stephan Jürgen Köhler,Elin Lavonen,Alexander Keucken,Philippe Schmitt-Kopplin,Tom Spanjer,Kenneth M Persson +5 more
TL;DR: Given the recommended limit of 4 mg L(-1) for chemical oxygen demand for Swedish drinking water, coagulation will need to be supplemented with one or more treatment steps irrespective whether climate change will lead to drier or wetter conditions in order to maintain sufficient DOC removal with the current increasing concentrations in raw waters.

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.
