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:

Preparation of polymeric aluminum ferric chloride (PAFC) coagulant from fly ash for the treatment of coal-washing wastewater
TL;DR: In this article, fly ash-based polymeric aluminum ferric chloride (PAFC) was prepared from fly ash leached with acid; the PAFC was used as a coagulant to treat coal-washing wastewater.
Journal ArticleDOI
Effect of recycling filter backwash water on characteristic variability of dissolved organic matter in coagulation sedimentation process
TL;DR: The physicochemical characteristics of the dissolved organic matter (DOM) in simulated raw water, corresponding filter backwash water (FBWW) and treated water at three recycling ratios of 2, 5, and 8%, including control without FBWW were evaluated using bulk properties, in addition to advanced characterization by molecular weight distribution (MWD), hydrophobicity, and fluorescence as mentioned in this paper.
Journal ArticleDOI
Effect of water treatment additives on lime softening residual trace chemical composition--implications for disposal and reuse.
TL;DR: Testing of WTR under reducing conditions demonstrated the potential for release of certain trace metals above applicable regulatory thresholds; additional evaluation is needed to assess management options where reducing conditions may develop.

Occurrence of a New Generation of Disinfection Byproducts
Stuart W. Krasner,Howard S. Weinberg,Susan D. Richardson,Salvador J. Pastor,Russell Chinn,Michael J. Sclimenti,Gretchen D. Onstad,Alfred D. Thruston +7 more
TL;DR: A survey of disinfection byproduct (DBP) occurrence in the United States was conducted at 12 drinking water treatment plants to obtain quantitative occurrence information for new DBPs (beyond those currently regulated and/or studied) for prioritizing future health effects studies.

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.
Journal ArticleDOI
Fundamentals, present and future perspectives of electrocoagulation.
TL;DR: This paper presents an in-depth discussion and consideration of the factors that need to be addressed for optimum performance of this technology.
