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.

Annu Matilainen,Egil T. Gjessing,Tanja Lahtinen,Leif Hed,Amit Bhatnagar,Mika Sillanpää,Mika Sillanpää +6 more
TL;DR: A review of the methods used for characterisation and quantification of NOM in relation to drinking water treatment can be found in this paper, where a number of methods have been proposed for NOM removal with varying degrees of success.

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.

TL;DR: In this article, the authors considered long-term records of the nature of water colour and coincident water quality and quantity in order to test hypotheses about increases in release of dissolved organic carbon from peat soils across the northern hemisphere.

Effects of natural organic matter removal by integrated processes: alum coagulation and PAC-adsorption
Małgorzata Szlachta,W. Adamski +1 more
TL;DR: An increase in the removal of the low molecular weight NOM was achieved when the PAC-adsorption process had been combined with coagulation, and a drop observed in the SUVA value after the process implied a decrease in reactive DOC forms and consequently a diminished risk that disinfection by-products might form.

Optimized coagulation of high alkalinity, low temperature and particle water: pH adjustment and polyelectrolytes as coagulant aids.
TL;DR: The results suggest that the coagulation mechanisms in the removal of dissolved organic matter and particles are different, which may be exploited for optimized coagulated for the typical source water in practice.

Removal of hexachlorobenzene from soil by electrokinetically enhanced chemical oxidation.
TL;DR: Results show that the position of electrodes in the system and the way in which Fenton's reagent was added to the system has a significant influence on the treatment efficiency of electrokinetic Fenton process.
