Investigation on Chlorination of Uranium Oxides With CCl4 and HCl Gas

open access: yesHe huaxue yu fangshe huaxue, 2022
In this study, the chlorination mechanism and influencing factors of uranium oxides(mainly U3O8) were studied by using CCl4 and HCl gas as chlorination reagents respectively. The chlorination of U3O8 powder was studied with CCl4 as chlorination reagent.

Modifications to sorption and sinking capability of microplastics after chlorination

open access: yesWater Supply, 2023
Chlorination disinfection in water treatments may be highly destructive to microplastics (MPs). Herein, low- and high-dose (concentration–time values at 75 and 9,600 mg min L−1, respectively) chlorination processes were used to simulate short-term ...

Effects of chlorine disinfection on RO membrane biofouling at low feed water temperature for wastewater reclamation

open access: yesJournal of Water Reuse and Desalination, 2022
Chlorine disinfection has been reported to be ineffective in controlling RO membrane biofouling in some projects. Feed water temperature is a crucial factor in the formation of RO membrane biofouling.

Potential cancer risk estimates from trihalomethanes in peri-urban settings of Kawama East of Mufulira, Zambia

open access: yesJournal of Water and Health, 2022
In this study, we report the formation and cancer risk estimation of trihalomethanes (THMs) emanating from ‘ex-situ’ chlorination of shallow hand-dug well water obtained from a peri-urban area of Mufulira District, Zambia.

The Case for LED-UVC as a Primary Disinfectant for Small Sustainable Drinking Water Systems [PDF]

open access: yesMATEC Web of Conferences, 2019
High loads of natural organic matter (NOM) in source water increase levels of toxic byproducts during disinfection, including trihalomethanes (THMs) which are formed when NOM is chlorinated.
