Project Description:
§ Proposes to determine the feasibility of developing control software capable of reliably regulating dissolved oxygen levels in the activated sludge process in wastewater treatment plants by quickly detecting hardware malfunctions that impact dissolved oxygen levels.
Proposed Outcomes:
§ Prototype control software will be developed and field-tested in a wastewater treatment plant.
Anticipated Benefits:
§ Potential to reduce California energy consumption at wastewater treatment plants by 5-10%. If you assume only a 5% reduction in energy in 80 large treatment plants the energy savings would be approximately 49 gWh/year. There are about 800 treatment plants in California.
§ Potential to reduce the number of accidental releases of improperly treated wastewater from treatment plants that seek to save energy by optimizing dissolved oxygen levels.
