Industrial Wastewater Treatment Plant
Blower Upgrade

The Quincy Industrial Wastewater Treatment Plant cleans high strength food processing wastewater. PACE provided civil and environmental engineering design for this three phased project. Phase 1 evaluated benefits of energy conservation by optimizing operation of the aerobic treatment process. Using a state-of-the-art bioprocess model, PACE determined that power use could be reduced by about 2,300 MW hours/year by replacing two 600-hp centrifugal blowers with two 320-hp positive displacement blowers. Phase 2 developed plans, specifications, and estimates for installing new blowers with integral variable frequency drives and a process control PLC for adjusting the aeration to match the demand in the aerobic treatment units. For Phase 3, PACE provided construction assistance and completed monitoring and verification of the energy savings.
