Research Area: Energy

Our Objective

Energy self sufficiency for wastewater treatment plants. This would be pursued as two parallel energy-related research efforts. One for reduction in plant energy demand through lower-energy alternatives to secondary treatment, i.e., activated sludge. The second research effort will examine the capture of energy from wastewater to support plant operations, and ultimately the financial benefits from its export.

The research builds on the work done under the completed Operations Optimization Challenge, for which the goal was to achieve 20 percent improvement in cost and/or energy consumption. Get the related fact sheet.
