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:

Transformation of sulfonylurea herbicides in simulated drinking water treatment processes
TL;DR: Current drinking water treatment processes are not likely to provide sufficient protection for human population from exposure to SUs, and parts of the SUs were transformed into certain stable products with triazine/pyrimidine structures which might be of potential health risks in chlorination process.

Algal control and enhanced removal in drinking waters in Cairo, Egypt.
TL;DR: Applying ferric chloride and ferric sulfate as coagulants to waters treated with the combined pre-oxidation procedure effectively reduced algal count and better the total organic carbon reduction and residual aluminum in the treated water.

Removal of nanoparticles (both inorganic nanoparticles and nanoplastics) in drinking water treatment – coagulation/flocculation/sedimentation, and sand/granular activated carbon filtration
C.H.M. Hofman-Caris,Patrick S. Bäuerlein,W.G. Siegers,Svenja Mintenig,Ruth Messina,Stefan C. Dekker,C. Bertelkamp,Emile Cornelissen,Annemarie P. van Wezel +8 more
TL;DR: Nanoparticles, such as metallic ones like Ag, Au and TiO2 as well as nanoplastics, are applied in or emitted by a wide variety of products or stem from degradation as discussed by the authors .
Journal ArticleDOI
Overlapping anthropogenic effects on hydrologic and seasonal trends in DOC in a surface water dependent water utility
TL;DR: It is found that, during the study period, overlapping global change processes in the watershed had the net effect of increasing the DOC aromaticity, as measured by SUVA254, at moderate to high discharge levels during the late spring and early summer and the autumn and early winter.

Book
Organic geochemistry of natural waters
TL;DR: The first part of the book as mentioned in this paper is a general overview of the amount and general nature of dissolved organic carbon in natural waters, and the second part is a summary of the data that has accumulated from many disciplines over the last decade.

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.
Journal ArticleDOI
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.
