Wastewater Pure Oxygen Injection

PURE OXYGEN INJECTION FOR WASTEWATER TREATMENT

For the treatment of municipal wastewater tanks or facilities with much smaller volume and footprint than air-fed sludge plants, turn to Mazzei. Using pure oxygen allows for much higher oxygen uptake rates (OUR) to be sustained than when air is used. In a Mazzei pure oxygen injection system, wastewater is pumped through one or more high efficiency Mazzei® Venturi injectors, forcing oxygen to aspirate into the wastewater. The resulting gas-water mixture is discharged back into the tank/facility through Mazzei MTM™ Mixing Nozzles and Nozzle Manifolds for greater oxygen transfer. No blowers are required which reduces energy costs and noise. For high dissolved oxygen requirements, Mazzei’s Pipeline Flash Reactor™ can also be utilized.

BENEFITS OF MAZZEI FOR OXYGEN MIXING AND CONTACTING:

  • Small Footprint
  • No Limits on Water Depth
  • Low Operating and Installation Costs
  • Energy-efficient Oxygen Transfer
  • Subsurface Injection of Oxygen to the Bottom of the Tank where the Head Pressure of the Water Column Facilitates Higher Oxygen Solubility
  • Very High Oxygen Utilization Rates
  • The Ability to Feed Oxygen Selectively into the Various Stages to Optimize the Treatment Process
  • Very Fine Regulation of Dissolved Oxygen Levels in the Wastewater to Prevent the Growth of Nocardia Microorganisms, which Cause Severe Foaming Problems in Conventional Pure Oxygen Plant Configurations
