“…The aforementioned related studies from the literature were given as a literature comparison table in Table 2. As a result, in the literature, the COD removal % was reported between 69.2 and 97.8 during the treatment of sugar industry wastewater via the electrochemical process [14–23] . Additionally, TOC removal % was reported within 20 and almost complete [10,25,26,28–35] .…”

The sugar industry is one of the most wastewater‐producing industries and it contains high content of organic and inorganic substances. Treating and reusing wastewater has significant importance because sugar industry needs to use a high volume of water. In this study, sugar industry wastewater was treated under subcritical conditions and the impacts of reaction temperature and duration over TOC removal percentage were investigated. Additionally, the impact of NaOH concentration over TOC removal percentage was examined. The highest TOC removal was obtained almost 95 % in the presence of 0.1 M of NaOH at 240 °C for 90 min of reaction duration. Treatment of sugar industry wastewater by subcritical water oxidation followed the second‐order reaction kinetic model and the activation energy was found as 11.41 kJ/mol. Furthermore, the intermediate products were identified via GC‐MS.

“…Following the categorization into municipal domestic and industrial wastewaters , it might be stated that the organic pollution of domestic wastewaters is rather uniform and dominated by readily degradable organics originating mainly from human excretion, personal care products, and household runoffs. In contrast to that, industrial wastewaters show the most diverse compositions ranging from biodegradables such as food industry exhaustion to streams containing non‐biodegradable and persistent molecules such as industrial dyes .…”

Electrochemical technologies for the treatment of industrial and municipal wastewaters, potable water, and groundwater, are presented, focusing on the main water constituents: inorganics, organics, micropollutants, and microorganisms. Removal of inorganic compounds by electrodialysis, electrocoagulation, and capacitive deionization as well as removal of organics and micropollutants by electrosorption, advanced oxidation processes, and anodic oxidation with boron‐doped diamond electrodes are reviewed. Electricity can be generated by degradation of organic compounds in microbial fuel cells and dehalogenation by cathodic reduction minimizes toxic substances in water. The disinfection of different types of water is also presented and it is shown that electrochemical methods offer versatile approaches to contribute to an sustainable future water management.
