Generally, Sewage Treatment Plants(STPs) are complexes systems in which a range of physical,chemical and biological processes occur. However, their performance strongly depends on theknow-how acquired by the field-engineer. Recently, in order to solve this situations, variousoperation and management technologies based on the Instrumentation, Control and Automation(ICA)have been developed. As a economies-environmental affect point of view, this study was for theperformance evaluation and assessment of results from the Smart Operation System(SOS) in fullscaleSTP. The SOS in STP consisted of the process monitoring module, including real-time influentprediction and effluent simulation, and the Smart Air Control(SAC) module. According to theresults from field test for 2 years, the results of economical evaluation, amount of benefits and costsaving by the SOS have shown to be much higher than that of traditional operation. Nevertheless,the removal load(kg/yr) of BOD 13.3 %, COD 28.2 %, TN 44.4 % and TP 20.8 % were increased,respectively. Remarkable improvement of removal load could be achieved after the SOS wasadapted. It was concerned that the SOS offer a user friendly functionalities and cost saving neededby the field-engineers. In addition, it was expected that the results of this study would supplyhelpful information for design and cost saving for the SOS in full-scale STP. |
