• Output of 20 – 29 ppm of free oil to comply with most of content discharghe requirements
• Closed loop with very low gas consumption design
• Vertical option with small footprint and motion insensitve applications

In most upstream installations, most notably offshore, a secondary treatment step represent the final step where discharges of 20 – 29 ppm of free oil content are permissible. Ovivo Float vertical units are used, almost exclusively, for off-shore installations, where real estate is at a premium and motion is a concern. Ovivo also offers multi-cell horizontal IGF units, which although prevalent on on-shore installations, can be adapted for off-shore application as well if required.

• Customized packaging
• Low induced gas consumption
• Proven and reiable technology

Ovivo offers total packaged solutions by integrating bespoke size and materials into project specific applications. Performance can further be increased by addition of coalescing packs to:

• Enhance oil separation efficiency
• Reduce residence time requirements

Ovivo-Float IGF designs optimize the principles of Stokes law by using finely dispersed gas to reduce the apparent density of the oil and solids; increase their droplet size and greatly increase buoyancy through coalescence. Pressurized water passing through the eductor creates a vacuum at the gas suction port, whereby the gas drawn from the vapor space in the IGF Vessel and induced into the water stream. This is essentially a closed loop with very low gas consumption. Velocities through the eductor and inlet distribution are critical and must be maintained near constant flow for best efficiency. A pump is provided to recirculate clean water through the eductors to maintain optimum gas entrainment.

Flow rates capacity from 3,000-100,000 BWPD per vertical unit. Horizontal units up to 150,000 BWPD per unit.

Typical influent oil concentration: 250 – 500 ppm
Typical outlet oil concentration: 15 – 30 ppm
