Sulfate radical based advanced oxidation processes for agro-industrial effluents treatment: A comparative review with Fenton's peroxidation

Agro-industrial wastewater management becomes a major task while environmental regulations are becoming stricter worldwide. Agro-industrial wastewaters are known by high content of organic pollutants that cause an adverse effect on the water bodies. Industries are looking for efficient, easy-to-use and affordable treatment processes. Sulfate radical based advanced oxidation processes (S-AOPs) are arising as suitable alternatives for agro-industrial effluents treat-ment. In this review, the major findings regarding the application of this technology for real agro-industrial wastewater depuration are discussed. Moreover, these technologies are compared as an alternative to Fenton's process, which is a widely studied advanced oxidation process and with high efficiency in the treatment of agro-industrial effluents. The studies already carried out are promising, but there is stilla great lack of studies in this area and using this technique.

Automated summary

Agro-industrial wastewater management is becoming increasingly important as environmental regulations become stricter worldwide. These wastewaters are known for high organic pollutant content, which adversely affects water bodies. Industries are seeking efficient, user-friendly, and affordable treatment processes. Sulfate radical based advanced oxidation processes (S-AOPs) are emerging as suitable alternatives for treating agro-industrial effluents. This review discusses the major findings regarding the application of this technology for real agro-industrial wastewater treatment, comparing it with Fenton's process, which is widely studied and highly efficient in treating agro-industrial effluents. Promising results have been achieved in existing studies, but there is still a lack of research in this area and using this technique.
