Abstract
A saturation vessel for treating waste water is provided with a hollow body member having a fluid inlet and outlet. A plurality of diffuser plates are positioned one above the other within the body member. A perforated screen member surrounds the diffuser plates. Waste water engages the diffuser plates and the screen to increase the saturation level of air within the waste water. The fluid outlet discharges the air-saturated water to a desired location. The level of waste water agitation is varied by changing the shape and configuration of the diffuser plates and screen member.
