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:

M.A.C.K. Hansima,J. Ketharani,D.R. Samarajeewa,K.G.N. Nanayakkara,Ajith C. Herath,Madhubhashini Makehelwala,Suresh Indika,Kbsn Jinadasa,S. K. Weragoda,Yuansong Wei,Yuansong Wei,Rohan Weerasooriya +11 more
TL;DR: In this paper, the authors examined the AEM fouling by Ca2+ and humic acid (HA) using synthetic groundwater using vibrational spectroscopy and found that both inter-and intramolecular interactions, including hydrophobic cationπ interactions among HA-Ca2+ complexes, were active in membrane fouling.

Coagulation-Flocculation Technology in Water and Wastewater Treatment
TL;DR: In this paper, the principle of coagulation and flocculation process is discussed, which includes the charge neutralization and various binding mechanisms e.g. interparticle bridging, sweeping coagulations, and absorption.
Dissertation
Utjecaj oksidacije na učinkovitost uklanjanja prekursora trihalometana iz vode koagulacijom i flokulacijom
TL;DR: In this article, the effect of oxidation on the impact of removing the trihalomethane precursor from the water by coagulation and flocculation was investigated, and it was concluded that the most efficient coagulant is Fe2(SO4)3, with potassium permanganate preoxidation and the addition of activated charcoal powder.

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.
