The removal of nitrogen from tile drainage by means of bacterial reduction was investigated. The major nitrogen form in tile drainage is nitrate (approximately 98 percent). The process required that an organic carbon source be added to the waste to accomplish reduction of the nitrogen. The bacterial process was used in two configurations, anaerobic filters and anaerobic deep ponds. The projected costs for both processes are approximately 90 dollars per million gallons.
