Abstract
A nozzle for use in treating waste water is provided with a hollow body member having fluid inlets and outlets. A glide tube having a tapered interior is positioned within the body member. A boulet is positioned within the glide tube to form a pressure drop zone and an expansion zone between the glide tube and the boulet. The fluid inlet receives highly or super-saturated liquid from which micro bubbles of gas are produced within the pressure drop and expansion zones. The fluid outlet discharges the liquid and micro bubbles to a desired point of use.
