Treatment of Textile Wastewater by Sulfate Radical Based Advanced Oxidation Processes (SR-AOPS)

Abstract

In wastewater from the textile industry, there are many substances like the ones found in dyes, metals, and organics that are very harmful and the conventional treatment methods that are being used in the industry, cannot get rid of them. But it's different with the advanced oxidation processes (AOPs), particularly sulfate radical-based (SR-AOPs), they are very good at removing these hazardous pollutants. This article focuses on the study of Fe/Mn-biochar as a catalyst in persulfate (PS) for the treatment of textile effluent. Its porous structure, large surface area, and redox activity play a crucial role in the promotion of radical production and the abasement of the pollutant. Using XRD and FTIR, they announced the results showed that this element was workable. The Fe/Mn-biochar effectively decomposed Rhodamine B by applying a second-order kinetic model. It could be used more than one time and still work fine for three cycles, but on the third cycle, the efficiency will decrease and it can be regenerated. In brief, Fe/Mn-biochar is a new, eco-friendly, and relatively cheap option for industrial wastewater treatment using SR-AOPs which could be the new possible solution for future large cuts in industrial water pollution.
