Demand Response System for Wastewater Aeration Using On-line Off-gas

Water resource recovery facilities typically receive the highest loading flowrate (water to be treated) when the cost of energy is also the highest. The overlap between the peak flowrate and the most expensive energy price intensifies both the cost of treatment and the concurrent greenhouse gas (GHG) emissions. This study looked at how an innovative on-line off-gas analyzer demand/response system coupled with advanced modeling software maximize the reliability of cost savings projections for WRRF during peak energy demand periods.
