This paper presents a study of the wastewater treatment station of the ?Low Danube", in which were analyzed the variations of physico-chemical parameters of the influent and effluent, as well as the efficiency of the treatment processes. The requirements on the quality of the effluent are in accordance with Council Directive 91/271/EEC on wastewater treatment, which aims is to prevent the negative effects of discharges of urban waste water and waste water from certain industrial activities. The parameters analyzed are: chemical oxygen demand - potassium dichromate method, biochemical oxygen demand in water, suspended matter, total nitrogen and total phosphorus. This study was made following the improvement of the quality of treated water after the implementation of a new management system. At the same time, a comparative study of quality indicators is presented before the implementation of a management system in 2012, on 2015 when the original version was used and then the improved version of 2018. Influent showed large variations of parameters during the monitoring period, especially of organic load and suspended matter. The final results are presented through the three-year cleaning efficiency that demonstrates a significant improvement in the treatment process.
