Nitrate salts are used widely in many areas as fertilizers in agriculture, explosives, oxidizing agents in the chemical industries, and as food preservatives especially to cure meats. If the range of nitrates increases in environment shows many dangerous and ill effects. Conversion of nitrate was needed. In this study TSS, TDS, BOD, COD and 93 % highest conversion of nitrate was found from the optimized conditions. The final form of the proposed model equation for the percentage conversion of nitrate was Ys=0.93(1-e-0.698t). Where Ys = percentage conversion of nitrate and t= conversion time (hr).The model showed good agreement with experimental data by generating average absolute relative deviation (AARD) of about 0.92± 2.9% conversion of nitrate from steel industry effluent using membrane separation process.
