Özet

The study presents an estimation of pollutant (biological oxygen demand (BOD) and suspended solids (SS)) and nutrient (nitrogen and phosphorus) loads from the domestic wastewaters discharged directly to the Aegean Sea and the Mediterranean Sea from the coastal provinces in Turkey. Current national statistical database (TUIK) including population, degree of the treatment, wastewater flowrate per capita was used for the estimation and pollutant loads per capita were assumed based on the degree of the treatment. The results showed that about 2.2 million cubic meter of municipal wastewater is discharged directly to the seas, causing annual loads of 8.5 kton BOD, 13.4 kton SS, 9.8 ktons N and 1.8 ktons P. Finally, modification of the plants to advanced levels with nutrient removal were assessed in terms of their positive effect.
