The continuous discharge of pharmaceutical compounds into aquatic environments has become a serious environmental concern due to their persistence, bioaccumulation potential, and ecological toxicity. Conventional wastewater treatment plants are not fully effective in removing pharmaceutical micropollutants such as antibiotics, analgesics, and antiparasitic compounds. This study investigates the application of the Fenton Process (Fe²⁺/H₂O₂) for degradation and mineralization of pharmaceutical contaminants present in clinic greywater collected from Nagpur.
Greywater samples were collected from selected discharge points near Shraddha Clinic, Rameshwari-Manewada region. The collected wastewater was characterized for pH, COD, TOC, turbidity, conductivity, and pharmaceutical concentration using LC-MS/HPLC techniques. The study focused on degradation of selected pharmaceuticals including Enrofloxacin, Oxytetracycline, and Albendazole.
Experimental optimization was performed by varying pH, Fe²⁺ dosage, hydrogen peroxide concentration, and reaction time. The Fenton process showed maximum degradation under acidic conditions around pH 3.
Fe^(2+)+H_2 O_2→Fe^(3+)+⋅OH+OH^-
Under optimized conditions, COD removal efficiency reached 89–93%, TOC reduction reached 74–82%, and pharmaceutical degradation exceeded 95% for most target compounds.
Economic analysis indicated that the Fenton process is technically feasible for tertiary wastewater treatment with an estimated operational cost of ₹38–₹58/m³ depending on reagent consumption. The study concludes that the Fenton process can serve as an efficient and scalable treatment method for removal of pharmaceutical emerging contaminants from greywater systems.
