Air Strippers

​Air Strippers are designed for removal of volatile organic compounds and other contaminants for groundwater remediation or municipal applications. Air strippers use the simple approach of transferring the contaminants from the water stream to the air stream. PRM low profile air strippers use forced counter current air distributed across horizontal trays to remove volatile organic compounds from the water stream.

Air Stripper

The PRM Low Profile Air Strippers provide an efficient and compact product for treating contaminated water. The contaminated water stream flows over a distribution weir and along the horizontal trays. Forced air is blown through the 3/16” diameter holes in the horizontal trays and forms a froth of bubbles generating a large mass transfer surface area where the contaminants are volatilized. The clean water exits the stripper and the off-gas vapors are treated as required. The PRM Modeler is used to determine the necessary contact time, number of trays and flow rate to achieve required volatilization.

 

Our strippers use a unique tension rod which allows the user to properly torque the trays in place to eliminate leaks. As the stripper and gaskets age the tension rods can be tightened to seal the gaskets, extending the life of the gaskets. 

 

The proprietary PRM design reduces fouling problems often associated with air stripping. The large diameter air distribution hole combined with the turbulent flow reduces build-up of oxidized iron. Should build up occur the trays are easily removed for cleaning. Additional access ports can be added to facilitate inspection and cleaning.

PRM STS Air Strippers

The efficiency of our low profile air stripper with added features for ease of use and operation!

STS Features:

  • Transparent Front Cover: Allows for ready visual monitoring during operation.

  • Standard Single Door Access: Easy air stripper maintenance and tray removal—Handles on each tray and door for user friendly functional design.

  • Integrated Blower: Incorporating the blower into the unit significantly reduces the overall footprint needed for the system, giving you placement flexibility during design. The integrated blower also makes repairs safer and simpler as the motor is removed directly from the stripper body without the complexity of piping which may hamper repairs.
