The Turborator® has been used successfully in installations throughout the United
States, Canada and other parts of the world for over 20 years and
has a proven track record in both retrofits and new installations.
The
Turborator® is a self aspirating submerged impeller aerator and mixer. When
the patented Turborator® impeller rotates in a liquid, a low pressure zone is created
behind each blade. This low pressure zone creates a strong vacuum
which draws air down the shaft and disperses as fine bubbles into
the surrounding liquid.
Air is
introduced up to 9’ below the surface without requiring a blower
or compressor. The air drawn by the pumping action of the
Turborator® is sheared by the vane edges of the high speed radial flow
impeller producing millions of micron sized bubbles. The long
retention time and high combined surface area of these micron
sized bubbles along with the thorough dispersion generated by the
mixing action of the impeller, substantially increases the oxygen
transfer efficiency and keeps solids in suspension. The high
velocity discharge design also prevents plugging or blockages
common in other types of aeration system.
The
Turborator®
has been used in both municipal and industrial applications
wherever mixing and aeration are needed. The following table lists
some typical applications for the Turborator®.
This list is not all-inclusive.
Performance/Design
The oxygen transfer efficiency is higher than other mechanical
self aspirating aerators due to the manner in which gas is
introduced below the liquid surface. In testing performed in
accordance to the ASCE "Standard for the Measurement of Oxygen
Transfer in Clean Water" Turborator®
units have oxygen transfer efficiency 18% greater than
competitor's equipment - based on the horsepower delivered at the
shaft.
Other advantages of gas introduction below the liquid surface
include the absence of surface splashing and mist formation which
release pathogens into the atmosphere and can cause ice build up
in cold weather climates. Ice build up can clog draft tubes, and
cause floating units to lose stability and capsize.
The simplicity of the Turborator®
design results in a durable, dependable, low maintenance system.
The basic components of the system include a severe duty electric
motor with a "V" belt drive mounted to a solid main frame, a heavy
walled steel shaft supported by heavy duty bearings, and the
patented Turborator®
impeller. The optional incorporation of a variable speed drive
gives the Turborator®
flexibility between pure mixing and mixing with increased aeration
to satisfy the most stringent process requirements.
Turborator®
units are available in sizes from 5 - 25 HP and can be installed
on a fixed support or mounted on floats to suit the application.
