A dose optimization method of disinfection units and synergistic effects of combined disinfection in pilot tests
2022, Water ResearchCitation Excerpt :This results in higher inactivation efficiency of Bacillus subtilis spores and lower formation of trihalomethane and haloacetic acids (Chin and Berube, 2005; Jung et al., 2008). Sequential UV-chlorine (UV irradiation first, then chlorination) and UV/chlorine combined processes can effectively improve stability of water quality, decrease genotoxicity, and inhibit the formation of some DBPs by reducing disinfectant doses or generating advanced oxidation (Jia et al., 2019; Li et al., 2018a, 2016; Wang et al., 2014, 2011, 2012). Furthermore, ozone or UV pretreatment may remove some chlorine-resistant bacteria (Ding et al., 2019; Shekhawat et al., 2021).
Radical-promoted formation of dibenzofuran during combined UV-chlorine treatment on mono-substituted diphenyl ether
2021, Chemical Engineering JournalCitation Excerpt :Among them, combined UV-chlorine treatment has attracted wide attention. It shows obvious advantages in killing various microorganisms, and can reduce disinfectant demand and ensure lasting disinfection ability [3–5]. Moreover, combined UV-chlorine treatment is also a promising advanced oxidation process.
