Application of advanced oxidation processes to different industrial wastewaters.

This study examines the application of photochemical and non-photochemical advanced oxidation processes on the treatment of textile, Kraft bleaching, photoprocessing, and pharmaceutical wastewaters. Effects of reaction conditions on the treatment efficiency of industrial wastewater have been investigated. The results were evaluated in terms of biodegradability enhancement.

Treatment of pharmaceutical wastewater containing antibiotics by O3 and O3/H2O2 processes.

Ozonation of three different synthetic pharmaceutical formulation wastewater containing two human antibiotics and a veterinary antibiotic has been studied to enhance the their biodegradability. The effects of pH and initial chemical oxygen demand (COD) value as well as addition of hydrogen peroxide on ozonation process were investigated. Total organic carbon (TOC), COD, biochemical oxygen demand (BOD), and aromatic content (UV254) were the parameters followed to evaluate the performance of ozonation process.
