WASTE-WATER MANAGEMENT FOR ISTANBUL - BASIS FOR TREATMENT AND DISPOSAL

A number of studies have so far been conducted to assess the magnitude of pollution generated by domestic and industrial sources in the Ista nbul Metropolitan Area. They indicate that a management scheme for was tewater treatment and disposal should involve a total discharge of 15. 4 m3 s-1 with a potential pollution load of 330 tons BOD5 day-1 for 19 90. A scheme of this magnitude inevitably requires careful evaluation of receiving water characteristics, both from an oceanographic and a q uality standpoint. In this paper significant water quality parameters related to the Black Sea-Bosphorus Strait-Marmara Sea System are revie wed and incorporated in the evaluation of treatment and disposal alter natives. In this context, the pollution exchange between the Mamara Se a and Bosphorus is quantified, pollutant contents of the Mamara Sea an d discharges from the Istanbul Metropolitan Area are compared, and a n umber of scenarios are evaluated to define the optimum treatment and d isposal strategy.
