Abstract
An enhanced multiple compartmented (segmented or chambered) supplemental tank system that (i) adds another media to enhance wood chip denitrification, and (ii) includes a component for recycling treated wastewater back to the front end of the system with mainly nitrate-N recycled back and combined with organic carbon (present in wastewater) under anoxic to form nitrogen gas and CO. The latter uses an aeration pump and tubing to reduce soluble organics and assist with the conversion of ammonia-N to nitrite-N and nitrate-N.
