Purpose of a ShallowTray Low
Profile Air Stripper
To Remove Volatile Organic Compounds
(VOC s) from Groundwater and Industrial
(VOC's)
Waste Water
The rugged ShallowTray line of low profile
Z
air strippers is your answer – even for
difficult to remove acetone, chlorinated
and MTBE
This efficient air stripping technology is a
patented process that can help you avoid
the cost of GAC.

ShallowTray Advantages
Low Profile – The discreet size of a ShallowTray air stripper does not
advertise a contamination site. It is easily accessed for maintenance and can be

portable devise for pump tests, pilot studies, short-term cleanup or emergency
response.
Resistant to Fouling – Treatment trays have large 4.8mm
4 8mm aeration
holes. In addition, the turbulent action of the froth scours the surfaces of the
tray reducing built-up of oxidized iron.

anywhere

within the rated flow ranges. As the flow rate reduces, performance increases.
If site demands change, so can the ShallowTray system. The modular design
allows for the addition of trays which increases the removal of contaminants.
No Disposal
– ShallowTray systems have no packing or diffusers to
contend with and no costs associated with GAC breakthrough, fouling or
disposal and replacement.
Guaranteed Performance
- BISCO Environmental guarantees
your system will perform as specified under the conditions specified.
