Design: 103 mgd(mean daily flow)
BioWin Application – Operating Cost Savings
The situation…
Meets Current Final Effluent Requirements
Total N: 9.5 mg/LBOD: 15 mg/L
Aeration Control Strategy• Single airflow
control valve for each R/C
• Position controlled by any one of four DO probes in aerated zones
BioWin Application – Operating Cost Savings
The situation…
DO in aerated zones highly variable
Aeration power costs $NZ 1.7M annually
Explore cost saving potential of improved DO control strategies

BioWin Application – Operating Cost Savings
The application…
Compare Improved and Existing DO Control Strategy
Methodology:• Selected an “average week”
• Synthesized diurnal “reactor feed” profile
• Entered actual observed DO data
• Model calculated airflow rates
• Calculated power consumption from airflow
• Compared cumulative power consumption

Compare Improved and Existing DO Control Strategy
Methodology:• Compared cumulative power
consumption
• Generated cumulative power trend over one week
• Proposed control strategy improvements indicated significant potential power reduction

BioWin Application – Operating Cost Savings
Conclusions and benefits…
Annual Cost Savings: $NZ 399,000 (@ $0.083 / kWh)
Conclusions• BioWin simulation can be used effectively as a test
of the economic benefits of different aeration control strategies
• BioWin simulation is particularly appropriate for complex aeration systems where implementation is relatively costly
• Significant cost savings can be made by improving aeration control
Benefits• Cost saving NZ$399,000 per year (at
$0.083/kWh)
• Reduction in air consumption by @ 20%
• Reduction in blower power consumption by @13,000 kWh/d (8% of total power)
• Return on investment
• Immediate Cash Saving
• Improved Process & Stability
