Ozonation / Disinfection―Wastewater

Ozone (O3) gas is a powerful oxidizer and strong disinfectant, and it is becoming the primary oxidant of choice in many wastewater applications. Ozone inactivates bacteria extremely rapidly before water discharge, which has significant advantages including:

  • Rapidly inactivating fecal coliforms
  • Reducing chlorine disinfection byproducts
  • Increasing dissolved oxygen (DO) in the effluent

The key to the use of ozone is the efficient transfer of ozone gas to solution and the effective removal of untransferred and entrained gas. The Mazzei GDT™ process accomplishes both.


  • Compact design
  • Easy to install and maintain
  • High-concentration ozone contacting
  • Works at any flow rate
  • Low operating costs
