REVOLIFT HS® takes oil separation performance far beyond typical induced gas flotation systems. As produced water moves continuously through multiple chambers, microbubbles are introduced to lift the smallest suspended oil particles to the surface where they are skimmed off, resulting in clean outputs. The system is purely hydraulic with no internal moving parts, providing continuous, trouble-free separation at rates up to 150,000 BWPD in a single vessel. Its multi-chambered, sequential treatment design handles variable flows and upsets without performance impact or short-circuiting. The REVOLIFT HS® can be custom designed to meet all of your specifications and solve your water problems.

How it works

REVOLIFT HS® uses fluid hydraulics coupled with microbubble flotation (MBF®) to optimize oil-in-water separation. The multi-chambered design has no internal moving parts and requires no mechanical adjustments. Produced water enters the chambers sequentially as microbubbles are introduced. Oil is lifted upon the bubble layer and is skimmed off by overflowing an oil weir. The water then flows into the next chamber where more microbubbles are introduced and more oil is separated. The process drives itself hydraulically through all chambers, and water exits the system at targets as low as <10 ppm.

Key Benefits


  • Efficient pre-engineered design reduces capital costs
  • No moving parts, which reduces costly failures and delays

Better Performance

  • Sequential treatment ensures thorough oil removal
  • MBF technology ensures cleaner water in the most challenging processes
  • High tolerance for upsets due to multi-chamber design with no short-circuit paths
  • No rotating seals, thus eliminating fugitive air emissions

High Flexibility

  • High-quality, wide operating range makes this treatment system a long-term asset
  • Wide turndown range handles variable flows without performance loss.
