Degradation Of Pharmaceuticals By Advanced Oxidation Process (AOP) In Low Quality Wastewater

The degradation of pharmaceuticals such as carbamazepine (CBZ) and gemfibrozil (Gemfi) through Advanced Oxidation Processes (AOP) represents a critical advancement in wastewater treatment, particularly in low-quality water scenarios. Effective AOP relies on the interaction of target compounds with hydroxyl radicals, necessitating careful consideration of water quality parameters, including UV transmittance (UVT%) and total organic carbon (TOC). Recent tests conducted by Atlantium revealed that CBZ degradation reached an impressive 98% from initial concentrations exceeding 100 µg/l, although this required a substantial hydrogen peroxide dosage of over 300 mg/l and a UV dose of approximately 2000 ± 400 mJ/cm². Meanwhile, Gemfi exhibited a remarkable degradation rate of 99.8%, achieving a concentration below 1 µg/l under optimal conditions. To enhance the efficacy of UV-based AOP, the HODTM UV technology integrates real-time monitoring systems that track essential parameters such as UVT, flow rate, and lamp power.
