Project Schedule/Status: Design scope for drying 2022; design of biogas optimization is underway. Dewatering building construction complete; digester upgrades at at 50% design.

PROJECT DESCRIPTION: This project is to fund the enhancements to our bio solids treatment facilities and bio solids recycling/disposable program. Bio solids (processed residuals from the treatment of domestic wastewater) contain nutrients and other qualities that improve soils and make them highly desirable to many area farmers within Harford County and elsewhere in Maryland. However, nutrient controls being imposed by the State Department of Agriculture and MDE to help protect the Chesapeake Bay are dramatically affecting the ability to recycle these materials. Reduced application rates and time of year restrictions have created a significant impact to our program. The study recommended advances to our solids treatment train, enhanced drying, dewatering, storage, beneficial utilization and optimization of biogas, and beneficial reuse of the dried bio solids. Optimization of the bio solids entails improvements to the digester system and is part of the digester upgrade.
