Removal of antibiotic resistance genes and pathogenicity in effluent from municipal wastewater treatment plant by plasma oxidation

Potential of non-thermal discharge plasmas for activated sludge settling: effects and underlying mechanisms

“…1 , which is similar to our previous study. 17 The sludge cracking experimental setup included a high-voltage discharge system and a sludge cracking vessel. The power supply used in this study was a high-voltage AC purchased from Dalian University of Technology, China.…”

“…To explore the contributions of different kinds of reactive oxygen species in the sludge cracking process, IPA and BQ were chosen as trapping agents of $OH and O 2 c − , respectively. [15][16][17] Fig. 8a and b show the effects of different concentrations of BQ and IPA on the sludge settling performance using SV 30 as an index, respectively.…”

“…Discharge plasmas use an advanced oxidation technology integrating photochemistry and electrochemical oxidation, which has been widely concerned in the eld of water sterilization and disinfection. [15][16][17] Under the action of an applied electric eld, high-energy electrons generated by the high electric eld bombard gas molecules to produce a large number of reactive oxygen species (such as 1 O 2 and $OH), which can break the cell wall of bacteria and cause death. Kang et al 18 inactivated Salmonella typhimurium by the discharge plasma and found that the reactive oxygen species attacks played a decisive role.…”

Modelling and optimization of membrane process for removal of biologics (pathogens) from water and wastewater: Current perspectives and challenges

“…In other locations, the United States Environmental Protection Agency (USEPA) has revised guidelines for improved surface water treatment rules, with a primary goal of safeguarding groundwater resources against the spread of disease-causing pathogens originating from infiltrating surface waters. Operators must assess the effectiveness of their treatment systems in removing pathogens if the incoming wastewater is contaminated [ 24 , 62 ].…”
