The Ministry of Environment(MOE) has determined to adopt a new policy mandates
municipalities to change the paradigm, which is the Sewage Treatment Plants(STPs) facilities consume
the high energy during sewage collection and treatment. As a economic-environmental point of view,
the term of 'Energy Independent Master Plan' implies that some STPs need to be improved to
perform a better energy saving and self-energy production with less cost and less energy consumption.
Low energy and process optimization system based on the smart air-quantity control system was
developed. It was composed of a real-time influent analysis and effluent simulation techniques. The
result of field-application for the smart air-quantity control system, electric power was saved 15kW ~
37kW, and saved 7.6 ~ 18,8 million won compared of conventional non-air-quantity control system.
