A Computational and Applied Approach to Determining the Pollution Load in Urban Wastewater Management in Van Province

Türkçe

This study evaluates pollution loads from point sources in the İpekyolu, Tuşba, and Edremit districts of Van Province by comparing both calculated and measured data. In this context, chemical oxygen demand (COD), total nitrogen (TN), total phosphorus (TP), and suspended solids (SS) loads were calculated using pollution design coefficients. The urban wastewater from these districts is also treated at the Van Central Advanced Biological Wastewater Treatment Plant (WWTP), and the pollution loads received and discharged from the plant were measured and compared with regulatory values. As a result, the total pollution load discharged into Lake Van was determined to be 4037 tons/year for COD, 576 tons/year for TN, 96 tons/year for TP, and 1121 tons/year for SS. The measured pollution load at the plant outlet was determined to be 2737 tons/year for COD, 391 tons/year for TN, 43 tons/year for TP, and 608 tons/year for suspended solids (SS). The calculated values for TN and TP loads exceed the specified limit values.
