ABSTRACT

Considering the widespread pollution and the need for taking drastic measures to protect the environment, it is necessary to constantly optimize the treatment stages within the wastewater treatment plants in order to meet the quality standards when discharging wastewater into surface water. The paper presents a study on a wastewater treatment plant in Romania that serves a municipality with a population of approximately 400,000 inhabitants, having a sewerage network working in a unitary system. The study followed the evolution of the concentrations of pollutants over a period of one year and their influence on the efficiency of the biological treatment stage. It was also aimed at optimizing the operation of the treatment processes and tracking the effectiveness of the measures taken in this regard. The efficiency of the biological treatment stage has been analyzed using the output parameters from the treatment plant. The main identified problems, which caused the increase of certain quality parameters above the maximum allowed limit and implicitly the decrease of the treatment efficiency was the occurrence of filamentous sludge bulking, which is characterized by the decrease of the sedimentation degree in the secondary clarifier. At the end of the paper, a conclusion is drawn regarding the influence of the input parameters on the overall treatment efficiency and also recommendations are made concerning the operation of the related equipment at optimum parameters.

Keywords: wastewater treatment, performance indicators, wastewater plant, sludge bulking, optimization
