Application of Advanced Oxidation Processes to Treat Industrial Wastewaters: Sustainability and Other Recent Challenges

Mechanism and Techno‐Economic Analysis of the Electrochemical Process

“…SnO 2 : The methylene blue complete degradation was done within 60 min of reaction time using operating condition of current density 60 mA cm −2 with 1 % potassium chloride (KCl). However, COD removal was 80.1 % after 120 min of electrolysis time under the optimum operating conditions 6. Polcaro et al.…”

“…Therefore, it is a challenging ecological concern to treat the toxicity of the wastewater produced during dyeing processes. Conventionally many treatment methods are being used for textile dyes including primary and secondary treatment methods of sedimentation 6, neutralization 7, chemical coagulation, mechanical flocculation 8, anaerobic treatment 9, activated sludge process 10, oxidation 11, etc. Since these methods cannot completely degrade the organic non‐biodegradable compounds, are insufficient and have some limitations, an effective tertiary treatment process is required 12.…”

The mechanism of water pollutant photodegradation by mixed and core–shell WO3/TiO2nanocomposites

“…The quantity (Q d ) of dye degraded was estimated in mg g −1 by subtracting the free dye concentration at time t (C t , mg L −1 ) from the dye concentration before light irradiation. Then, the decomposed quantity of the dye was calculated using eqn (2).…”

“…1 Due to rapid industrial growth, the environment has become highly contaminated with various organic and inorganic pollutants. 2,3 Dyes are common hazardous organic contaminants in wastewater. 4 They also impart color to the water and can produce harmful byproducts through chemical reactions.…”
