. From the standpoint of pollution, industrial wastewater has numerous physical and chemical pollutants. Various methods were being suggested for industrial wastewater treatment depending the nature of the industry. Saipa car industry emits various environmental pollutants in its different processes. Problems addressed in this study were related to central heating output effluent of Saipa Company, including water leakage in feeding water systems, high temperature and corrosive outlet effluent due to decreasing of pH. In this study several methods were carried out for effluent reuse as a pilot research. The pilot was based on waste prevention of water containing nitrate and its recycling in addition of cooling and solving the corrosion problem. The results showed that, the wasting water was avoided due to preventing leakage of feed water in system. Beside, by adding corrosion inhibitor material, in addition to reducing water temperature, the system's corrosion would be prevented. On the other hand, the components of corrosion inhibitor increased the nitrate level in effluent were reused using the research pilot. Meanwhile, the oxygen amount of in the water existed in system within a high volume was reduced by improvisation a heating coil. Finally, the percentage of water returned to the hot water system was up to 60%.
