The Venturi Aeration Wastewater Conditioner is a unique apparatus designed for injecting atmospheric oxygen into any liquid or sludge using the venturi principle. Wastewater, the motive fluid, is pumped through the high velocity nozzle into a low velocity mixing and oxidizing chamber where it is turbulently mixed with aspirated air. The hydraulic shear effect within the device reduces organic solids to macroscopic size as it releases and oxidizes imbedded gasses trapped within the organic solids. The device has both high alpha and beta values necessary for transferring oxygen into a liquid because the mixing occurs within the device itself.

The Venturi Aeration Wastewater Conditioner is neither a diffused air device that brings the air to the water, nor is it a mechanical aerator that brings the water to the air. It is a device that utilizes "micro sized bubble diffusion" along with a hydraulic shear, under two atmospheres of pressure, to produce a well mixed, highly conditioned liquid.

The wastewater is pumped through a Venturi Aeration Conditioner at a hydraulic gradient of 20 psig at the inlet and mixed, under pressure, at an air to liquid ratio of 2:1. This oxygen saturated liquid is continuously being discharged, and replaced by an oxygen deficient liquid resulting in well conditioned wastewater, that overcomes the resistance of the two film interface (air-liquid) that exists with a partially oxygenated wastewater.
