the Water Environment Research Federation (WERF) was in response to the identified need
for a predictive modeling tool that unifies prior WERF research information regarding
quantifying and managing energy consumption. CHEApet was created under OWSO4R07C
of WERF’s Optimization Challenge to model performance and energy consumption of waste
water treatment plants (WWTPs). Energy consumption, along with treatment process
emissions, contributes to a facility’s carbon footprint. CHEApet can be used to create a
baseline scenario, or inventory, of a utility’s carbon footprint for informational purposes as
well as to compare with hypothetical treatment plants. This kind of comparison allows the
user to identify facilities in the utility for energy optimization and the potential for biogas
recovery which can save in costs and improve the footprint of the facility.

To date this is an average of 1.1 tons per day and is a sellable product. The dewatered recycled phosphate load was reduced from 55% to 9% and the mixed liquor phosphorus inventory dropped from 4.9% to 4.4%. The cost of the facility was $2.5 million dollars, not including the cost of a building to house the recovery facility, with a projected return on investment of only 6 years.
