GasTran™ Systems
GasTran technology is the first commercially available solution to cost effectively treat waste streams with high doses of
ozone. The technology was developed in the 1990’s by two professors from Case Western Reserve University. In 2004
GasTran Systems was formed in Cleveland, OH to commercialize this technology for a wide range of applications, including
ozone injection (www.gastransfer.com). Spartan Environmental Technologies supplies complete ozone generator systems
and is an authorized distributor of GasTran ozone injection systems.
GasTran Rotating Packed Bed Technology
GasTran Units use specially engineered materials to shear an incoming fluid stream into ultra fine droplets. This process
dramatically increases the surface area of the fluid to facilitate proven chemical processes. A detail technical paper
describing the GasTran Process can be found in our technical library click on this link to open the document. GasTran
Technology is significantly more efficient than current alternatives because it is continuously shearing and coalescing the
liquid, exposing surface area to the gas medium. The drawing below illustrates the principal of operation of the GasTran
system.
1) Wastewater is sheared into ultra-fine droplets by motor-driven, spinning rotor
2) Ozone gas passes counter-current to wastewater in rotor
3) Ozone surrounds droplets and is absorbed into the liquid
4) Ozone reacts to oxidize the chemical and biological contaminants
5) Treated water discharges from the system
GasTran Ozone Injection Systems
Ozone has been used extensively in industrial wastewater treatment to reduce color, turbidity, COD and odor. The
following link on COD and BOD removal using the GasTran ozone injection system provides data on streams with various
levels of COD. GasTran At room temperature and atmospheric pressure, the half-life of ozone in water is less than 20
minutes, so achieving intimate contact with the wastewater is critical. Traditional ozone injection systems, while working
well in low dosing application can encounter difficulties when high does of ozone are needed.
GasTran Technology combined with an ozone generator system is the first commercially available solution to cost-
effectively treat industrial wastewater streams with ozone at high doses. The key is highly efficient mass transfer combined
with high gas to liquid (G/L) ratios. In addition, GasTran ozone injectors simultaneously degas unreacted or undissolved
ozone, minimizing additional equipment, space requirements, and preventing downstream off-gas problems.
