Eliminate denitrification system

The biological conversion is done in an attached growth, downflow, deep bed, mono-media filter. Dissolved oxygen is removed to create an anoxic environment for denitrification, and particulate matter is removed so insoluble phosphorous is removed, as well. The system adds supplemental carbon source or microbiological food needed to metabolize the nitrogen.

Technical details

A better way to convert nitrate nitrogen to nitrogen gas in effluent stream;
Carbon source can be fed on mass basis with feed-forward control and/or feedback control;
Users can set and hold the optimum desired nitrate concentration;
Least amount of dissolved oxygen gain in feed-water;
Run times and carbon usage approach 100% of theoretical filter bed loading limits;
