Innovative Nutrient Removal Technology Development

Technology Researchers from the University of Minnesota Department  of Civil Engineering and the 3M Corporate Process Technology Center  are evaluating the ability of aerated membranes to improve  wastewater treatment. These hollow membrane mats are supplied with  oxygen, allowing aerobic and anaerobic microorganisms to  simultaneously cleanse nutrients, pathogens, and organic  contaminants from wastewater.  Objectives: To develop and evaluate an inexpensive, low maintenance,  aerated membrane technology for the treatment of animal waste and  septic tank discharges that cause nutrient contamination of the  Great Lakes and coastal waters. Evaluate technology for its ability  to provide improved treatment and especially improved nutrient  removals. Evaluate the effectiveness of the technology in removing  nitrogen from animal wastewaters.
