Abstract

Industrial waste water from various refineries, bulk drug manufacturing processes, dye industries etc. is complex in characteristics. It contains various refractory toxic organics and their derivatives. In recent years, advanced oxidation processes (AOPs) have been attracting growing interest for the degradation of hazardous and non-biodegradable organic compounds. The AOP procedure is particularly used for the aromatics, pesticides, petroleum constituents and volatile organic compounds in industrial waste water. The goal of AOP procedures is the reduction of chemical contaminants and the toxicity to such an extent that the cleaned waste water may be reintroduced into receiving streams or a conventional sewage treatment. Advanced oxidation processes using Fenton's Reagent (Hydrogen Peroxide (H₂O₂) and Ferrous Ion) are popular amongst other oxidizing agents due to its cost effectiveness, oxidation potential and ease of waste water treatment. Photo-Fenton oxidation process reacts well with organic compounds and does not produce any toxic compounds during oxidation. All contaminant materials are converted to large extent into stable inorganic compounds such as water, carbon dioxide and salts through the process of mineralization. Photo-Fenton oxidation process destroys different phenols, nitro-benzenes, herbicides in water media and reduces COD in municipal waste water. Many research papers have been published on "Photo-Fenton Oxidation Process" however very limited information is available which studies the effects of various parameters needed for the development of Photo-Fenton reactor. In the present paper various kinetic and design parameters for the development of Photo-Fenton reactor have been studied. The present paper sets simple guidelines for the development of Photo-Fenton reactor.
