Application of Innovative Bioremediation Technology to N/P Removal Associated with Agricultural Operations, N/P Offset Generation and Ecosystem Services Market Trades

The proposed project combines an anaerobic digester with a predenitrification (PDNF) cell to reduce VS and N loads, which are subsequently nitrified in an innovative bioretention system. This system is a stacked bioretention system comprised of advanced media that removes P. Through recirculation pumping from a pre-nitrification (PRNF) cell to a post-nitrification (PONF) cell, N and VS loads are reduced to ensure that the system exceeds operational performance of a traditional RW system, without the typical clogging problems, while operating at a fraction of the Energy cost. The advanced media within these cells virtually eliminates P. The resulting N is very low in ammonia, eliminating odors, while providing a source of nitrate-N suitable for fertilizer. This innovative combination of a PRNF and CAD with a modified RW system utilizes the best elements of traditional technologies/methods in a manner that increases performance efficiencies, reduces or eliminates traditional systemic problems, reduces required Energy inputs and adds the benefit of decreased GHG emissions.
