S. Doing so will also eliminate the associated corrosion.
The system operates by pumping a side stream of raw, unscreened wastewater through a conical shaped oxygen transfer reactor. Gaseous oxygen is fed into the cone which generates an intense bubble swarm that has an exceptionally large gas/water interface. The inlet of the cone is sized to provide enough inlet water velocity to shear the oxygen bubbles entering the cone. The cone widens to a diameter which decreases the water velocity to a point below the buoyant velocity of the bubbles, keeping them suspended inside of the cone until they are dissolved. The system completely dissolves the gaseous oxygen into the water, realizing oxygen transfer efficiencies of 90-95%, before the water is blended back into the force main. There are no internal baffles or static mixers that could collect rags or stringy material and create maintenance problems.
