Evaluation of Technological Solutions to Enhance the Operational Efficiency of the WWTP “Apa-Canal” Magdacesti Municipal Enterprise

The present study proposes technological solutions to address the existing limitations by modifying the treatment system to enhance its oxidation potential. The case study focuses on the Magdacesti biological treatment plant, which has encountered a new source of pollution from the “Ocean Fish” factory. Under high loading conditions during the biological treatment stage, both the activated sludge and the biological film, composed of aerobic microorganism flakes, experience changes in their culture composition and lose their sedimentation properties. To overcome these challenges, implementing an anaerobic pre-treatment process and integrating the “Integrated Fixed-Film Activated Sludge” technology into the aerobic process are recommended for intensifying the biological treatment.
