Technical Abstract: Denitrifying woodchip bioreactors are sized to treat a portion of subsurface drainage flow from a given system. Over sizing them can create conditions under which unintended consequences could occur. A potential solution for treating additional water is to use a cascading series of bioreactor cells that come on line as overflow is initiated from the previous cell. A three-cell biorector of the described design has been engineered, installed, and operated in southern Minnesota on a 277-ha watershed. This presentation will highlight the instrumentation and early flow and water quality results from the first few months of operation.
