Biological Nutrient Removal (BNR) Mixing Equipment

Federal mandates for Biological Nutrient Removal (BNR) add additional energy demands and increased costs.  Pulsair mixing solutions use up to 80% less electricity and are more effective than traditional mixing methods.  BNR (Biological Nutrient Removal) process is a newly mandated requirement for wastewater treatment. Nutrients must be removed from the water before it can be discharged back into a body of water or stream. The purpose is to reduce the nitrogen, which tends to produce excessive plant growth. The Pulsair system functions both for aerobic and anaerobic denitrification by keeping solids in suspension with gentle mixing as the wastewater travels through the tanks.
