Abstract

This paper analyses the physicochemical indicators of wastewater quality (chemical oxygen demand (COD), biochemical oxygen demand (BOD₅), concentrations of suspended solids) during the summer months (June, July and August) in 2013 and 2014 in the wastewater treatment plant Čakovec, which is designed for secondary wastewater treatment. The summer months of 2014 do not show significant deviations in the values of certain indicators, but compared with the same months in 2013, the average monthly values are much lower and within the permitted maximum. Results in June, July, and August 2013 and 2014 indicated efficient wastewater treatment.
