GasTran technology is the first commercially available solution to cost effectively treat waste streams with high doses of
ozone in a single pass. The technology was developed in the 1990’s by two professors from Case Western Reserve
University.Spartan Environmental Technologies supplies complete
ozone water treatment systems and is an authorized distributor of GasTran ozone injection systems.
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
Ozone has been used extensively in industrial wastewater treatment to reduce color, turbidity, COD and odor. 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 can 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.
