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:

Coagulation optimization for low temperature and low turbidity source water using combined coagulants: a case study
TL;DR: In this paper, the coagulation optimization using coagulants of ferric chloride (FeCl3), polymer-polyaluminum (PAFC), and their combinations (FeCL3/PAFC) was evaluated by performing jar tests for treating source water with low temperature (<10uC) and low turbidity (1.5-8 NTU) i,n a typical North-China water treatment plant.
Journal ArticleDOI
Water pathways through the ages: Integrated laundry wastewater treatment for pollution prevention.
TL;DR: This review bridges the knowledge gap by delineating the feasibility of current technologies in laundry wastewater treatment and the experiences of various countries in adopting different approaches, and the feasible methods for collecting laundry wastewater are elaborated.
Journal ArticleDOI
Improved predictive capability of coagulation process by extreme learning machine with radial basis function
TL;DR: In this article, an attempt to improve the predictive capability of artificial neural networks for the coagulation process in a water treatment plant, extreme learning machine (ELM) coupled with radial basis function (RBF) neural networks were employed.

Aluminum-humic colloid formation during pre-coagulation for membrane water treatment: mechanisms and impacts.
Zhengyang Wang,Benoit Teychene,Talia E. Abbott Chalew,Gaurav S. Ajmani,Tao Zhou,Haiou Huang,Haiou Huang,Xiaohui Wu +7 more
TL;DR: Both short-term and long-term filtration results demonstrate that OC, rather than the Al(OH)3(am)-HS colloids, primarily caused membrane fouling, which can be utilized to optimize the operation of integrated precoagulation-LPMF systems on full-scale installations.

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.
Journal ArticleDOI
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.
