ABSTRACT
In this paper the analysis of „Lemna” municipal treatment plant performance is reported, the study covered a period of seven years (2009-2015). The efficiency of removal of such indicators as BOD5, COD and total suspended solids were examined. Despite the very high variability of concentrations in raw wastewater, high efficiency and reliability of the installation was found in all cases. The average removal efficiency of organic compounds and total solids was 94.23% for BOD5, 82.55% for COD and 76% for total suspended solids and was positively correlated with the load on these parameters in inflow.
