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:

The effect of drought on dissolved organic carbon (DOC) release from peatland soil and vegetation sources
Jonathan P. Ritson,Richard E. Brazier,Nigel Graham,Chris Freeman,Michael R. Templeton,Joanna M. Clark +5 more
TL;DR: In this article, the authors examined the impact of drought on the production and treatability of DOC from four vegetation litters (Calluna vulgaris, Juncus effusus, Molinia caerulea and Sphagnum spp.) and a peat soil, and found that mild droughts caused a 39.6% increase in DOC production from peat and that peat DOC that had been exposed to oxygen was harder to remove by conventional water treatment processes.

Optimization of coagulation with ferric chloride as a pretreatment for fouling reduction during nanofiltration of rendering plant secondary effluent.
TL;DR: The optimization of coagulation with ferric(III) chloride (FeCl3) as a pretreatment for nanofiltration was performed to reduce membrane fouling and achieve higher permeate quality and increased the flux recovery and chemical cleanliness after the membrane washing.

Integrated treatment of pharmaceutical effluents by chemical coagulation and ozonation
Muhammad Imran Ashraf,Muhammad Ateeb,Muhammad Hussnain Khan,Naseer Ahmed,Qaisar Mahmood,Zahidullah +5 more
TL;DR: In this paper, chemical coagulation was carried out by alum and lime for treating pharmaceutical industry wastewater employing chemical co-agulation and ozonation process and the results showed that the coagulant type and dose, settling time and pH ranging from 0.5 to 1.0 were investigated.
Journal ArticleDOI
Effect of extracellular polymer substances on the tetracycline removal during coagulation process.
TL;DR: Results show that the presence of extracellular polymeric substances could significantly enhance the removal efficiency of tetracycline in hydroxyl aluminium coagulation, and suggest that tyrosine and tryptophan inextracellular proteins acted as binding sites to capture tetrACYcline.
Journal ArticleDOI
Size-Controlled TiO(2) nanocrystals with exposed {001} and {101} facets strongly linking to graphene oxide via p-Phenylenediamine for efficient photocatalytic degradation of fulvic acids.
TL;DR: This approach supplies a new strategy to design and synthesize metal oxide and graphene oxide nanocomposites with highly efficient photocatalytic performance.

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.
