Abstract:

Wastewater treatment is fundamental to preserve the environment and to protect public health, both in urban and rural areas. Poorly treated wastewater with high levels of pollutants creates major environmental problems when discharged to surface water or land. The present study aimed to evaluate performance efficiency of Wastewater Treatment Plant (WWTP) in Skenderaj, Kosova, to assess the effluent and its suitability for discharge into river. Influent and effluent wastewater samples were collected during April 2016 to June 2016. Physico-chemical parameters analysed for evaluation of performance of WWTP were temperature, pH, dissolved oxygen, conductivity, total dissolved solids (TDS), total suspended solids (TSS), biochemical oxygen demand (BOD), chemical oxygen demand (COD), PO4-P and N-total. The BOD5, TSS and COD removal efficiency of WWTP in Skenderaj were 98.47%, 78.66% and 32.64 % respectively. The values of temperature, pH, dissolved oxygen, conductivity, TDS, TSS, BOD5, COD, PO4/P and N-total for the final effluent produced from Skenderaj WWTP meet the values determined by the European Union (EU), World Health Organization (WHO) Standards.
