Removal of natural organic matter in drinking water treatment by coagulation: A comprehensive review
TLDR
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.About:

Removal characteristics of microplastics by Fe-based coagulants during drinking water treatment
TL;DR: The removal behavior of polyethylene (PE), which is easily suspended in water and is the main component of microplastics, was investigated with commonly used Fe-based salts and it is believed these findings will have potential application in drinking water treatment.

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.

Natural organic matter removal by coagulation during drinking water treatment: A review
TL;DR: 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.
