COLDEP has developed an original vacuum airlift process after years of research at IFREMER and INSA Lyon. COLDEP sells high-performance, reliable and low energy solutions that can:

  • Move great quantities of water at low energy cost
  • Manage dissolved gas (stripping, dissolution...)
  • Separate suspended mater from water (particles, oil, microorganisms...)


Our system can be used in aquaculture, oil and gas industry, water desalination, food industry, effluent treatment...

We are continually developing our range of applications, contact us if you want more information or test our system.
