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.

Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process.
