Air Strippers

PRM Low-Profile Air Strippers

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