ORP aeration vs. ORP + Oxygen
//= $frontData["question_content"] ?>
Would anyone be able to help me determine the energy savings of an urban effluent WWTP (2500 PE, activated sludge, Aerzen blowers, more details on request) which currently operates with ORP alone but which could be fitted with an additional oxygen sensor. In terms of investment, the plant is recent and equipped with everything needed to install the transmitter and the sensor. They just have to be purchased. But I would like to know if the investment could be amortized in less than 100 years.
