Pack Tower Air Strippers

One of the ways to remove volatile organic compounds (VOCs) from wastewater is to use a pack tower air stripper. The pack tower is a counter-current design where the wastewater is injected at the top of the tower and the air is introduced at the bottom. In the middle of the tower, the packing material agitates the water and strips the contaminants. The contaminants are then released either to the atmosphere or to post treatment per your local regulations.

Some common VOCs removed include:

• Tetrachloroethylene (PCE)
• Dichloroacetic acid (DCA)
• Vinyl chloride (C₂H₃Cl)
• Trichloroethene (TCE)
• BTEX compounds (Benzene, Toluene, Ethylbenzene and Xylene)
• MtBE (Methyl tert-butyl ether)
• Hydrogen sulfide (H₂S)
• Carbon dioxide (CO₂)
• Ammonia or Azane (NH₃)

Each system is designed to maximize the surface area for the most effective mass transfer to suit your application. They can accommodate liquid flow rates from 5GPM to 7500GPM per vessel and range from 12 inches in diameter to 14 feet.
