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:

Recent Advancement of Coagulation–Flocculation and Its Application in Wastewater Treatment
TL;DR: In this article, a critical review on recent studies of coagulation-flocculation treatment processes of various industrial wastewaters is presented, where the limitations and challenges for the coagulated-fluctuation process such as toxicity and health hazard posed by inorganic coagulants, production of large amount of toxic sludge, ineffectiveness in removing heavy metals and emerging contaminants, increase in effluent color, inefficient pollutant removal using natural coagULants, and complexity of scaling up procedure are presented.

A review on chitosan-based flocculants and their applications in water treatment
TL;DR: The influence of structural elements of the chitosan-based flocculants on their flocculation properties are emphasized in this review by examining different flocculations mechanisms and their applications in the treatment of various wastewaters containing different pollutants.

Electrocoagulation and advanced electrocoagulation processes: A general review about the fundamentals, emerging applications and its association with other technologies
Sergi Garcia-Segura,Maria Maesia S.G. Eiband,Jailson Vieira de Melo,Carlos A. Martínez-Huitle,Carlos A. Martínez-Huitle +4 more
TL;DR: The electrocoagulation (EC) process is an electrochemical means of introducing coagulants and removing suspended solids, colloidal material, and metals, as well as other dissolved solids from water and wastewaters as discussed by the authors.

Removal of natural organic matter in drinking water treatment by coagulation: A comprehensive review
TL;DR: With the increased fluctuation of NOM in water (concentration and composition), the efficiency of conventional coagulation was substantially reduced, hence the need to develop enhanced coagulated processes by optimizing the operating conditions, developing more efficient inorganic or organic coagulants, as well as coupling coagulations with other water treatment technologies.

Interaction of ozone and organic matter in coagulation with inorganic polymer flocculant-PACl: role of organic components.
TL;DR: In this article, two model waters were used to evaluate the ozone effect on aquatic organic matter (AOM) removal by coagulation with inorganic polymer flocculant (IPF)-polyaluminum chloride (PACl).

Development of a control system for in-line coagulation in an ultrafiltration process
TL;DR: A control system for the in-line coagulation applied in an ultrafiltration process was developed and it was found that the system performs well; adaptation to changing conditions is achieved adequately and sufficiently fast.

Characterization and coagulation performance of solid poly-silicic-ferric (PSF) coagulant
TL;DR: In this article, an inorganic polymer, liquid poly-silicic-ferric (PSF) coagulant, with different Si/Fe molar ratios was prepared using water glass, FeSO 4 ǫ 7H 2 O and NaClO 3 by co-polymerization.

Assessing dewatering performance of drinking water treatment sludges.
TL;DR: A comparison of the dewaterability of a range of water treatment plant sludges has been completed through computation of dewatering performance indicators for a diaphragm filter press, showing that high coagulant doses adversely affect both aspects, leading to filter area requirements larger than might otherwise be expected.

Improved coagulation performance using preformed polymeric iron chloride (PICl)
Ta Kang Liu,Ching Ju Monica Chin +1 more
TL;DR: In this article, the authors evaluated the coagulation performance of simple FeCl3 and polymeric iron chloride (PICl) having various polymer yield, and found that the use of PICls seemed to produce a similar reduction in turbidity and TOC when compared with using FeCl 3 as a coagulant under typical range for coagulations; however, the treatable region was broadened to lower pHs.
