Comprehensive treatment of urban wastewaters using electrochemical advanced oxidation process

Mechanism of N,N-dimethylformamide electrochemical oxidation using a Ti/RuO2–IrO2 electrode

“…14,15 Electrochemical oxidation is considered environmentally friendly. 16,17 Due to its advantages such as easy controllability and little secondary pollution, many researchers have conducted in-depth studies on electrochemical oxidation. 18 The method has been widely used in the treatment of wastewater from the printing, dyeing, smelting, and electroplating industries.…”

Preparation of low-cost functionalized diatomite and its effective removal of ammonia nitrogen from wastewater

“…The rapid development of urbanization and industrialization in most countries has led to a large amount of waste water being discharged into rivers and lakes (Fan et al 2021). These wastewaters contain many types of pollutants, such as ammonia nitrogen, phosphorus, dyes, bacteria, organic matter, etc (Fiorentino et al 2019;Rajasekhar et al 2020;LaMartina et al 2021). Among them, excessive ammonia nitrogen (NH + 4 -N) in water bodies will cause severe eutrophication and pose a serious threat to the water environment (Cheng et al 2019;Li et al 2020a).…”

Effect of Electrode Type on Bacteria Removal and Chlorine and Radical Production in Electrochemical Water Disinfection

“…Water disinfection can also be performed by electrochemical disinfection systems, as they are more effective than conventional disinfection devices [6][7][8][9][10]. An important advantage of electrochemical disinfection is that disinfecting chemicals can be produced in situ with minimal application area [11,12].…”

“…Another variation of the electrochemical reaction process is the hybrid use of elecrodes [7,8,18,28,[35][36][37], or combining electrolysis with other techniques such as nanofiltration [38], membrane technology [23], sunlight [39,40], Ozone [41], etc. The above-mentioned works present comparably successful results, but do not generally attribute the reason to a particular aspect of the overall mechanism.…”

“…In case of disinfection with direct oxidation, electrochemical reactive voltage is applied to induce electron exchange (hence current) and decrease the respiratory activity of bacterial cells and ultimately cause them die [31]. This method is based on the electrochemical oxidation of intracellular coenzyme A [8,36,43,44].…”
