Abstract

The treatment of high-salinity organic wastewater is an ongoing environmental challenge, especially as climate patterns change. Increased rainfall, a consequence of global climate change, can significantly alter the composition and behaviour of wastewater, affecting treatment efficacy. Advanced Oxidation Processes (AOPs), such as Fenton processes, photocatalysis, and ozonation, have shown promise in degrading organic pollutants. This study evaluates the effects of increased rainfall on the salinity and organic pollutant profiles of wastewater and investigates the performance of AOPs under these changing conditions. The findings reveal that while increased dilution from rainfall lowers salinity levels, it also disperses pollutant concentration, impacting reaction kinetics. Modified AOP techniques with optimized catalysts and pH adjustments improve treatment efficiency in varying conditions.
