A Review of Hybrid Process Development Based on Electrochemical and Advanced Oxidation Processes for the Treatment of Industrial Wastewater

International Journal of Chemical Engineering, Год журнала: 2022, Номер 2022, С. 1 - 15

Опубликована: Авг. 8, 2022

Nowadays, increased human activity, industrialization, and urbanization result in the production of enormous quantities wastewater. Generally, physicochemical biological methods are employed to treat industrial effluent wastewater have demonstrated high efficacy removing pollutants. However, some contain contaminants that extremely difficult remove using standard processes. Previously, electrochemical hybrid advanced oxidation processes (AOP) were considered a viable promising alternative for achieving an adequate treatment strategy such instances. These rely on hydroxyl radicals, which highly reactive oxidants efficiently break down found effluent. This review focuses removal from effluents through integration techniques. include electrooxidation, electrocoagulation/electroflocculation, electroflotation, photo-Fenton, ozone-photo-Fenton, sono-photo-Fenton, photo-electro-Fenton, ozone/electrocoagulation, sono-electrocoagulation, peroxi/photo/electrocoagulation. The data acquired over 150 published articles, most laboratory experiments, process is more effective than standalone

From complex molecules to harmless byproducts: Electrocoagulation process for water contaminants degradation

Desalination and Water Treatment, Год журнала: 2024, Номер 319, С. 100532 - 100532

Опубликована: Июнь 14, 2024

As a realistic decontamination strategy and an economically critical component of long-term water surveillance, detailed understanding electrocoagulation processes (ECP) for the remediation contaminants remains vital. When compared to chemical coagulation, ECP delivers greater removal capacities comparable particles does not require any additions. The EC approach generates numerous metal ions in solution by applying electrical current. resultant electro-generated coagulants comprise hydroxides (MeOH-), which function as efficient adsorbent organic pollutants (OPs) inorganic (IOPs), causing formation rise flocs onto electrolyte surface via sweep flotation. For deeper comprehension wastewater, this research critically examines existing trends. It focuses on mechanistic insights electrodes systems, addition myriad catalysts influence various operational parameters reaction mechanism. Ultimately, study builds freshly published uncover varied applications, namely strategies that integrate with treatment process. prospects are promising multifaceted owing its adaptable capabilities, integration possibilities other advantages.

Review on the impact of heavy metals from industrial wastewater effluent and removal technologies

Heliyon, Год журнала: 2024, Номер 10(23), С. e40370 - e40370

Опубликована: Ноя. 15, 2024

The incidence of water pollution in developing countries is high due to the lack regulatory policies and laws that protect bodies from anthropogenic activities industrial wastewater. Industrial wastewater contains significant amounts heavy metals are detrimental human health, aquatic organisms, ecosystem. focus this review was evaluate sources treatment methods wastewater, with an emphasis on technologies, advantages, disadvantages, innovation. It observed conventional (such as flotation, coagulation/flocculation, adsorption) had shown promising results but posed certain limitations, such generation volumes sludge, relatively low removal rates, inefficiency treating metal concentrations, sensitivity varying pH. Recent technologies like nanotechnology, photocatalysis, electrochemical coagulation have advantages over for removing metals, including higher improved energy efficiency, greater selectivity specific contaminants. However, costs associated these advanced remain a major drawback. Therefore, we recommend future developments technology reducing both waste generation.

Coagulation process for the removal of color and turbidity from wet coffee processing industry wastewater using bio-coagulant: Optimization through central composite design

Heliyon, Год журнала: 2024, Номер 10(7), С. e27584 - e27584

Опубликована: Март 19, 2024

The growing problem of industrial pollution in developing countries, especially Ethiopia, has sparked serious issues about the quality water, particularly when it comes to effluent from wet coffee processing industries. In response, this study investigates potential utilizing natural coagulants, Acanthus sennii C., Moringa stenopetala B., and Aloe vera L., either individually or combination, for treatment effluent. Methodologically, systematically varies operational parameters, including coagulant dose, pH levels, stirring speed, time, evaluate their impact on coagulation efficiency. Experimental data undergo statistical analysis, employing ANOVA, while computational optimization techniques are employed using Design Expert software determine optimal conditions. Notably, blended form three coagulants emerges as promising, yielding conditions 0.750 g/L dosage, 8.76, agitation speed 80.73 rpm, time 19.23 min. Under these optimized conditions, achieves remarkable removal efficiencies, approximately 99.99% color 98.7% turbidity. These findings underscore efficiency form, sustainable wastewater processing.
