Special Issue Information

Dear Colleagues,

Under the global COVID-19 pandemic, rapid transmission of severe acute-respiratory syndrome coronavirus 2 (SARS-CoV-2) occurs via contact or inhalation of viral droplets and aerosols. To avoid SARS-CoV-2 infection, intensified disinfection procedures have been adopted in indoor and outdoor settings and during drinking water and wastewater treatment with chlorine-based disinfectants. There is no doubt that the application of chlorine-based disinfectant plays an important part in fighting against the COVID-19 pandemic. However, the formation of disinfection byproducts (DBPs) in water induced by the reaction between disinfectant and water matrix inevitably poses a great challenge to water quality.

In view of the above observation, this Special Issue will focus on manuscripts (research papers, reviews, short communications) related to the research and development, policy, implementation, and management of DBPs in water and wastewater treatment.

Manuscripts in this Special Issue are expected to include:

  • Occurrence of DBPs in drinking water and wastewater;
  • Identification of unknown DBPs;
  • Formation mechanism of DBPs;
  • Toxicity of DBPs;
  • Removal of DBPs in water;
  • Safe disinfection processes during the COVID-19 pandemic.

The permanganate/bisulfite (PM/BS) process is a novel oxidation process, which can degrade micropollutants within several seconds. As natural organic matter (NOM) ubiquitously exists in an aquatic environment, the PM/BS process will inevitably react with NOM, which may impact the disinfection-by-products (DBPs) formation during subsequent chlorination. This study investigated the effect of PM/BS pre-oxidation of NOM on DBP formation. It was found that TOC removal reached a plateau when the molar ratio of PM to BS was 1:5. Increasing ratios of PM to BS decreased the intensity and area of fluorescence spectroscopy. PM and BS doses, pre-oxidation time, pH of solutions and concentration of Br impacted the formation potential of various DBPs. PM/BS pre-oxidation decreased the formation of TCM while increasing the yields of N-DBPs, thus increasing the risk of water quality. Calculated toxicity analysis showed that a general increase in CTI was observed with PM/BS pre-oxidation, indicating that PM/BS pre-oxidation had a negative effect on risk control of overall cytotoxicity. Although the PM/BS process could accelerate the degradation of micropollutants, the elevated DBPs formation, especially highly toxic N-DBPs, needs enough attention to control water-quality risk.
