Project Status
Project Update
The project team’s main technical focus has been on Task 2 – Design Fabrication and Installation of Advanced Sludge Separation Technologies and Task 3 - Monitoring of Baseline Sludge Treatment System. The project is progressing actively as planned to meet upcoming milestones.
The Issue
For many cities and towns, wastewater treatment plants (WWTPs) are the largest energy consumers that account for up to 3 percent of global electricity consumption and are among the largest GHG emitters at nearly 1.57 percent of global GHG emissions . Anaerobic Digestion (AD) is the commonly used conventional sludge treatment technology used at WWTPs. Unfortunately, AD process does not capture all the latent energy in wastewater, is not economically feasible for WWTPs smaller than 5 MGD in size and is a significant source of GHG emissions.
Replacement of incumbent AD process with innovative and more efficient sludge treatment technologies is an essential step to take to achieve decarbonization of WWTPs.
Project Innovation
The proposed project aims to implement and demonstrate three innovative advanced sludge separation treatment (ASST) technologies to reduce Wastewater Treatment Plant (WWTP) energy consumption and greenhouse gas (GHG) emissions. These innovative ASST technologies include two sludge thickening technologies (Suspended Air Flotation Thickener (SAF) and Biosolids Filtration Thickener (BFT)) and one sludge destruction technology (Ultra Energy Efficient Super Critical Water Oxidation (Ultra-SCWO)).
Project Benefits
This project will result in the ratepayer benefits for GHG reductions, greater electrical cost savings, electrical reliability, and operational & capital cost savings from using advanced and innovative sludge treatment technologies instead of less efficient conventional sludge treatment technologies including anaerobic digestion. Assuming a market penetration of 25% of advanced sludge treatment systems, we expect 250,000 metric tons CO2e of GHG emission to be avoided and 0.38 TWh of energy to be saved every year.
