Reducing Energy Usage in Wastewater Treatment

In most municipalities, wastewater treatment plants typically account for the highest energy usage. This project works with the wastewater industry (trade allies and plant managers) to determine specific process improvements that also reduce overall energy usage. To that goal we provide marketing to trade allies and WWT facilities to increase awareness of the program and foster greater buy-in. We work with clients to estimate savings and incentive amounts while our Evaluation, Measurement, and Verification contractor ensures savings attribution to the program. We also provide technical support to individual facilities to compare various energy efficiency alternatives and then to help the staff or poject engineers complete the DCEO application.

The aeration systems in a wastewater treatment plant can account for 54% or more of overall energy usage. We support the DCEO Clean Water Energy Efficiency program which promotes high efficiency aeration technology, including but not limited to: HE Aeration Blowers, Fine or Ultra Fine Bubble Diffusers, and Oxygen Sensor Devices. We also provide other custom measures to improve the wastewater process such as: hyperboloid mixers, efficient digestion mixers, sludge thickeners, and high-pressure UV lamp controls.
