An in tank sludge mixing system
Aquabio Ltd - Jetox Aeration and Mixing
The basic principle of Jet Aeration exploits two phase nozzle technology to enable high velocity contact mixing of air (or oxygen) and a liquid.
A single phase 'sidestream' of pressurised liquid is recirculated in a manifold and through a 'primary' jet nozzle. Immediately after this nozzle an air stream is injected at low pressure either directly from the atmosphere or from low-pressure air blowers. Intimate contact mixing is achieved at this interface before the combined air/liquid stream passes through a 'secondary' nozzle, at high velocity, and into the main body of mixed liquor. The effect of a sudden drop in pressure at the primary nozzle assists to entrain air into the secondary nozzle chamber and the high velocities at the interface cause a shear effect producing fine bubbles. This mixture of liquid and fine bubbles travels through the secondary nozzle and extends as a 'plume' into the tank.
The Jetox system can be installed with external or internal manifolds to suit the application.
