WASTEWATER MANAGEMENT IN THE AUTOMOBILE INDUSTRY

Wastewater from an automobile manufacturing company provides the material of this study. Separate treatment of cyanide—bearing wastes, end-of-pipe effluent and sewage versus collective treatment of the three wastes was evaluated. Experimental results indicated that high quality effluent could be obtained using the two proposed schemes. Furthermore, the initial as well as the current costs for both alternatives were almost the same. However, biological treatment is recommended since it solves the problem of the wastes in the plant using one treatment system which can be easily controlled.
