Application

 

Removal of dissolved phase Volatile Organic Compounds (VOC’s) from contaminated water 

 

Features and Specifications

 

  • North East Environmental Products (NEEP) were the original inventors of low profile air stripping technology.  Their Shallow Tray® brand continues to holds a very strong international position
  • A wide range of system capacities are available
  • The NEEP Modelling program helps in selection of system capacity to suit water flow rate and treatment requirements
  • Air stripper bodies are constructed of either stainless steel (rectangular) or polyethylene (cylindrical)
  • The basic Air Stripper unit supplied by ERR includes the following components:
    • sump with standard process nozzles for air, water and instruments
    • aeration trays with gaskets and fastening latches
    • cover with standard process nozzles for water inlet and off-gas outlet plus a mist eliminator
  • Compliance with Australian electrical ratings and standards is attained by locally sourcing blowers/motors and control systems

Ordering Information

 

Selection of an appropriate model and number of trays for a specific application requires at least the following information:
  • maximum water flow rate
  • influent water - concentration of dissolved VOCs
  • effluent water - target concentration of VOCs 
  • influent water temperature
 
 Key additional components required to operate the air stripper system are:
  • Blower (pressure or vacuum)
  • Transfer pumps — in-feed and discharge
  • Instruments, indicators, sensors, control systems

 

At our client's option, ERR can supply any or all of these components and, in addition, provide the service of design, fabrication, installation and system commissioning.
