Biological Nutrient Removal (BNR)
BNR systems are configured in trains of alternating anaerobic, anoxic and aerobic processes. The process steps combine to steadily degrade solids and nutrient content to meet wastewater discharge quality.
To deliver a superior mixing outcome each tank installation in the train must maximize the contact of the waste stream with the anoxic or aerobic bacteria that will remove the nutrients. Philadelphia Mixing Solutions has developed an axial flow impeller, the ARI 2, specifically for anoxic BNR processes. The ARI 2 delivers mixing energy into the corners of the blending tanks to keep solids in suspension and encourage
maximum biological activity.
The downward thrust of the axial flow produces mixing at the bottom of the tank and reduces surface turbulence and air incorporation that can reduce anoxic activity. The result is a more effective biological process that lowers output nutrient content as the waste stream moves through successive tanks.
