Injectors and nozzles for aeration and mixing

SEPRA sells components and offers engineering services for custom designed, innovative gas/liquid contact systems. These are based on:

  • MAZZEI injectors – allow efficient gas/liquid transfer
  • MAZZEI mixing nozzles – multiply injector performance increasing mixing and mass transfer coefficient
  • complete GDT contact/degas sytems

Proposed solutions are characterized by:

  • high gas/liquid transfer yield
  • low energy consumption
  • easy installation, also for revamping
  • no maintenance
  • low noise (no blowers or compressors)


  • waste water treatment
  • fish farms
  • ozone systems
  • carbonation e decarbonation
  • degassing and stripping
