Tannery industry is one of the forebearer industries in the world The tanning process aims to transfigure skins in stable and non-perishable products namely leather.It is recognized as a serious environmental threat due to high chemical levels including salinity, organic loading (chemical oxygen demand or load, biological oxygen demand),inorganic, dissolved, suspended solids, ammonia, total nitrogen chromium chloride, sodium and other salt residues. The aim of the study is to determine the treatment of the tannery wastewater by using Radiant-Fenton oxidation reactor. To study the characteristics of the sample tannery wastewater such as pH = 10, colour = 600, BOD = 2066 mg/l, COD = 6200 mg/l, TSS = 1400 mg/l, Turbidity = 785 NTU, Chloride = 1000mg/l were analyzed. Initially the treatment of tannery wastewater was carried out by Radiant-Fenton Oxidation Reactor at lab scale, the reactor having a volume of 2.35 litres with inner and outer dia of 2.54cm and 5.08cm fabricated with inner tube of height 1.5 feet and 2 feet with a breadth of 120mm and 80mm respectively with UV visible of 36 watts. The organic loading rate of 0.3kg/COD/m3 with a flow rate of 8.6 l/min were applied to reactor. With the HRT as 8hrs, COD and TSS removal was taken to be influencing parameter. The Photon-Fenton Oxidation Reactor was operated for 8 hours and gets the final output as COD = 700 mg/l, BOD = 200 mg/l, colour =300, turbidity = 30 NTU, TSS=95%, pH 5, Chloride 150 mg/l. It has achieved the maximum removal efficiency of 95%
