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:

Novel insights into the coagulation process for pharmaceutical wastewater treatment with fluorescence EEMs-PARAFAC.
TL;DR: It is shown that coagulation was effective to remove contaminants in the effluent of pharmaceutical wastewater, and the optimum coagulate dosage was 0.5 g/L, where the removal efficiency of total organic matter (TOC), UV254, turbidity and NH4+-N were achieved.

Raising the efficiency of coagulation treatment of the Dnieper River water
TL;DR: Paper showed synergism of the combination of preliminary ozonization and coagulation at a fixed coagulant dose and the use of ozone doses within the range 2.9–3.6 mg/dm3 is most expedient in summer months, when the content of the total organic carbon in the water increases.

Seasonal forecasting of lake water quality and algal bloom risk using a continuous Gaussian Bayesian network
TL;DR: In this paper , a Gaussian Bayesian Network (GBN) was developed for seasonal lake water quality prediction, which is a simple class of continuous BN and can be used to forecast, in spring, total phosphorus (TP), chlorophyll-a (chl-a), cyanobacteria biovolume and water colour for the coming growing season in lake Vansjø in southeast Norway.

Ahmed Samir Naje,Shreeshivadasan Chelliapan,Zuriati Zakaria,Mohammed A. Ajeel,Peter Adeniyi Alaba +4 more
TL;DR: In this paper, the major and minor reactions of EC process with operational parameters, design of EC cell, mass transfer studies and modeling, and industrial wastewater applications are reviewed, and the effect of electrodes geometry is considered to enhance the conductivity of the cell and reduce energy consumption.
Journal ArticleDOI
Natural organic matter characterization by HPSEC and its contribution to trihalomethane formation in Athens water supply network.
TL;DR: Various THM levels in the supply network of Athens are illustrated as a result of the different reservoirs' water qualities, and a suggestion for a limited application of chlorine dioxide is made in order to minimize THM formation.

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.
