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
