New UV irradiation and direct electrolysis—promising methods for water disinfection

Electrochemical treatment of phenolic waters in presence of chloride with boron-doped diamond (BDD) anodes: Experimental study and mathematical model

“…4 shows the values of active chlorine concentration obtained at different electrolysis time by DPD method. The concentration of oxidants decreased as the anodic current density increased: this can be explained by considering that the main mechanism of active chlorine conversion to chlorate and chlorites [6,10,35] is the oxidation by OH radicals in the anodic reaction zone, which rate increases with current density [16]. In this work higher values of oxidant concentrations were obtained in the electrolyses performed at the highest values of Re.…”

Studies on process parameters for chlorine dioxide production using IrO2 anode in an un-divided electrochemical cell

“…The main difficulty concerning with these studies is that all of them are as patents, and explicit details on cell design, experimental parameters and conditions, etc., are not accessible. Some of the available literature from publications by Gordon and his co-workers [32][33][34][35][36] and Bergmann group [24,[37][38][39] are mainly related to analyzing chlorine chemistry and problems of by-product analysis for chlorination, or in liquors of chlorine disinfectants produced electrochemically.…”

Microwave photochemistry V: Low‐pressure batch and continuous‐flow microwave photoreactors with quartz mercury electrodeless discharge lamps. Photohydrolysis of mono‐chloroacetic acid

“…A flow-through photoreactor for disinfecting drinking, waste, and feed-water has been designed. 15 Also a microwave sterilizer was described. 16 Spherical or cylindrical EDLs 17 have been used to remediate air, water, or other fluids.…”
