PRM 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.

Experience Matters! PRM has been manufacturing Low Profile Tray Air Strippers for over 30 years!

 
Standard Air Stripper Features: 
  • Heavy gauge 304 stainless steel construction to reduce stress fractures

  • In- House manufactured systems – flow rates from 10 to 1000 GPM

  • Unique tension rods to secure trays – no clamps to break

  • Access ports on each tray for inspection and cleaning

  • Easily replaceable gaskets

 

Options:
  • Fully integrated packages or trailer mounted for pilot testing

  • False trays for potential foaming issues with surfactants

  • PRM Modeler is available for proper system sizing

  • Reduced height sumps for lower profile in tight buildings

  • Automated acid cleaning systems

 

Low Profile Air Stripper Process

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

PRM STS Air Strippers—the efficiency of our low profile air stripper with added features for ease of use and operation.

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. 

 

Air Stripper Modeler

 

PRM has developed an online Air Stripper Modeler tool for design assistance purposes.
The Air Stripper Modeler allows the user to correctly size their equipment for specific project
requirements. The model is run immediately following the data entry and the results are emailed
to you for project use.

TERMS AND CONDITIONS OF USE FOR MODELER
 

•   This is a free tool that is used for site specific applications in designing the proper low profile
    air stripper system. The modeler is a general reference given the years of experience and
    project suitability. This tool generates a model based on given influent conditions. A safety
    factor should always be considered for site specific applications since the probability of
    background interference or other variables is typical. If surfactants or any other foaming
    materials enter the process stream the results will be inaccurate. Contact the PRM design
    team for such applications. Use of the modeler provides certain information to PRM as
    requested in the user entry fields. This information may be used for solicitation or marketing
    efforts by PRM only. This information is considered confidential and is not distributed outside
    of PRM. The use of the modeler for intents other than its design is
     prohibited.

 

•   Use of the Air Stripper Modeler provides certain information back to PRM as requested in the
    user entry fields.  This information may be used for solicitation or marketing efforts by PRM
    only.  This information is not distributed outside of PRM.

 

•   Use of the model for intents other than its design are prohibited.
 

•   Abusive use of the Air Stripper Modeler is prohibited.  This modeler operates from PRM’s
    servers and abusive use may create congestion or resultant delays that may affect other
    users.

 

•   The Air Stripper Modeler is used as general reference given years of experience and project
     suitability.  This tool generates a model of results based on given in-fluent conditions with no
     background interference.  A safety factor should always be considered for site specific
     applications since the probability of background interference or other variables is typical.

 

•   The  Air Stripper Modeled results would be inaccurate and not recommended if surfactants or
    any other foaming materials enter the process stream.
