Transvac Venturi Aerators are a mass momentum exchange device which uses the energy of pressurised liquid to entrain, mix and pump air into a secondary liquid.
We have been supplying Venturi Aerators and Mixers into the Water Treatment industry for decades, with hundreds of projects successfully carried out. As a result, we are able to share extensive process and project expertise to support your next tank aeration projects.
Tank Aerators : Principle of Operation
Transvac Venturi Aerators use the energy of pressurised liquid to entrain air (or oxygen) into a secondary liquid for the purpose of aerating and mixing in a process vessel or pipeline.
Recirculated liquid is pumped from the process vessel and into the Aerator where it is accelerated through a unique vortexing jet. This results in an area of low pressure and high velocity into which air is drawn and intimately mixed with the liquid under conditions of high shear.
The mixture is then forced through the venturi, receiving a pressure boost sufficient to overcome the backpressure created by the head of liquid in the process vessel. The high energy turbulent plume is freely discharged with a velocity capable of entraining the surrounding liquid. Following this, the plume changes to a buoyant low-density mixture rising to the liquid surface to complete the aeration and mixing process.
As well as our Venturi Aerators (liquid entraining air), we also offer Venturi Jet Mixers (liquid entraining liquid) to provide tank mixing/agitation.
