Biological Double-Efficiency Process as an Advanced Wastewater Treatment Method to Achieve Substantial Energy and Water Savings
Advanced Biological Wastewater Treatment Method to Achieve Substantial Energy and Water Savings.
There was a substantial period of inactivity due to COVID-19, therefore the agreement was extended to 3/31/2022. The recipient supervised equipment delivery and inspection in August. Due to Stay in Place orders, no on- site construction could occur in August. In late October 2020, the recipient did a project site condition checkup. The recipient intends to accomplish the following prior to the end of the year: complete electrical installation, complete leak repair and redo hydrostatic testing, complete equipment installation, complete laboratory setup, and continue leak repairs.
This project is demonstrating an efficiency technology that targets one of the major energy using steps in wastewater treatment. The Biological Double Efficiency Process (BDP) combines state of the art, easy to maintain aeration technology, airlift circulation/dilution technology, and an integrated all-in-one bioreactor technology to replace the separate anoxic and aerobic tanks associated with secondary clarifiers. The BDP is based on simultaneous nitrification and denitrification principles.
The BDP technology could reduce energy and water consumption and costs at wastewater treatment plants while also meeting California's growing water and wastewater needs. In addition, the BDP technology could provide advantages of reduced energy and land use, carbon footprint (CO2 emissions), waste sludge generation, and operation and maintenance costs. The technology has the potential benefits of substantial 50 percent energy reduction, 30 percent less capital, 50 percent less land required, 50 percent reduction in operation and maintenance costs, and water savings opportunities.
