Ozonation / Disinfection―Wastewater

Ozone (O3) gas is renowned for its potent oxidizing properties and robust disinfection capabilities, and is increasingly establishing itself as the primary oxidant in numerous wastewater treatment applications. Its swift bacteria inactivation prior to water discharge yields several significant advantages:

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

The key of ozone utilization lies in the efficient transfer of ozone gas into solution and the effective elimination of untransferred and entrained gas. The Mazzei GDT™ process achieves both objectives effectively.
