Abstract/Contents

Abstract: Wastewater treatment plants (WWTPs) currently face substantial costs from the large amounts of energy they consume and the large volumes of biosolids that must be disposed. However, WWTPs have the potential to evolve into resource recovery centers, creating products such as clean water, renewable electricity, biofuels, biomaterials, and fertilizer. Their large energy loads also position them to offer demand management services to electric utilities. To benefit the most in the markets for these products and services, WWTPs must achieve greater control over their plant production rates so they can buy or sell at optimal times. Several strategies may be available to modulate production: control of plant of influent flow and use of the sewer system as flow equalization; scheduling of trucked waste arrivals; and fuel storage (as biogas, biomethane, or brown grease). Meanwhile, new technologies like anaerobic secondary treatment and established technologies for enhanced anaerobic digestion (AD) have the potential to substantially change production and consumption rates at WWTPs, impacting their ability to produce various goods and services. This research uses field data and deterministic and stochastic optimization techniques to identify optimal investment and operating policies for WWTPs within this changing context.
