Aeration Turbine
Encyclopedia
Aeration Turbines are designed to aerate and mix fluids industrially. They are foremost used in brewing, pond aeration and sewage treatment plants.
Aeration Turbines are designed for mixing gases, usually air, with a liquid, usually water. They can serve additional purposes like destratification
, agitator
or pump
.
There are numerous design variations in use or newly entering the market. Most are centrifugal, where fluid enters at the axis and exits around the perimeter of the rotor. Aeration Turbines can run open or in a housing. Some designs have bladed rotors which leads to more splashing and those need to run close to the surface, which is an obvious sign of lesser efficiency.
Generally the performance efficiency of Aeration Turbines is very high, the space requirement is compact, both at high reliability and all those factors reduce operational cost.
The use of Aeration Turbines in industry is still underdeveloped especially with waste water treatment. With raising population and the growing strain on clean water supplies such environmentally friendly solutions are becoming more important.
The technology allows a more decentralized approach to waste water treatment as sewage
can be oxigenised at pumping stations for bacteria to start breaking down the sewage before it even arrives at centralized processing plants.
Aeration Turbines are more and more entering industry because of their significantly higher efficiency and reduced size of used gear compared to other methods of aeration. This means less investment into process infrastructure and substantial savings to both the overall cost but formemost running cost for electricity.

Destratification
Destratification is a process in which the air or water is mixed in order to eliminate stratified layers of temperature, plant, or animal life. The first example of destratification was in 1919, in a small resorvoir....

Agitator (device)
An agitator is a device or mechanism to put something into motion by shaking or stirring.-Manual agitator:* Manual dishwashers* A rock can be a device used to agitate dirt and other solids from fabric in washing* A stirring rod...
or pump
Pump
A pump is a device used to move fluids, such as liquids, gases or slurries.A pump displaces a volume by physical or mechanical action. Pumps fall into three major groups: direct lift, displacement, and gravity pumps...

Sewage
Sewage is water-carried waste, in solution or suspension, that is intended to be removed from a community. Also known as wastewater, it is more than 99% water and is characterized by volume or rate of flow, physical condition, chemical constituents and the bacteriological organisms that it contains...
