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.
