摘要：The aim of this work is to asses conditions for implementation of a Biological Nutrient Removal (BNR) process in the Wastewater Treatment Plant (WWTP) of Moreni city (Romania). In order to meet the more increased environmental regulations, the wastewater treatment plant that was studied, must update the actual treatment process and have to modernize it. A comparative study was undertaken of the quality of effluents that could be obtained by implementation of biological nutrient removal process like A2/O (Anaerobic/Anoxic/Oxic) and VIP (Virginia Plant Initiative) as wastewater tertiary treatments. In order to asses the efficiency of the proposed treatment schemata based on the data monitored at the studied WWTP, it were realized computer models of biological nutrient removal configurations based on A2/O and VIP process. Computer simulation was realized using a well-known simulator, BioWin by EnviroSim Associates Ltd. The simulation process allowed to obtain some data that can be used in design of a tertiary treatment stage at Moreni WWTP, in order to increase the efficiency in operation.
