"RBC on Steriods"

 

From sea level to 17,000 ft elevation, WesTech's STM-Aerotor is a proven, reliable and simple treatment process that delivers a great quality effluent while saving money and energy. 


 

The STM-Aerotor captures atmospheric air with each rotation, draws it down into the mixed liquor, and slowly releases the compressed air as coarse bubble aeration. The aeration of the system is achieved without the use of blowers, aeration piping, or diffusers.

  

Koester and WesTech can design and supply complete package plants to meet the strictest effluent requirements.

 

WesTech's STM-Aerotor is a compact system minimizing footprint and operator attention. Package plants can range from the most basic control scheme to fully automated systems. The STM-Aerotor has the ability to accommodate seasonal fluctuations in flow rates. Multiple trains of the system can easily be taken off-line or placed on-line based upon demand.
