At many installations, the ISF achieves effluent oil concentration in the range of 5 to 10 parts per million. Our ISF cells are designed to provide 90% or greater oil removal and 80% or greater removal of non-oil solids at full design capacity. This represents a major improvement over earlier hydraulic flotation systems which typically experienced performance degradation at only 40% of design capacity. Product Range • Individual units for flow rates of 380 m 3 /day to 20,670 m 3 /day (2400 BPD to 130,000 BPD) • Separation efficiency up to 95% Overview The WEMCO ® ISF ® (Induced Static Flotation) System is a leading technology for environmentally safe treatment of secondary produced waters. The ISF system is a simple, hydraulically operated gas flotation machine that delivers efficient oil/water separation with complete process containment. Effective oil recovery and water treatment are achieved simply and economically, with operator and environmental safety ensured by the completely enclosed flotation process.

All equipment is skid mounted for rapid installation and start-up. The ISF is an induced gas flotation system through which a high-velocity stream of recycled clarified water enters the cells containing influent water through eductor nozzles in the bottom of the vessel. This induces a recirculating flow of air or gas from the vessel freeboard into the process water, and a unique eductor arrangement distributes small gas bubbles uniformly throughout the cell volume. These bubbles lift contaminants to the liquid surface forming a froth layer, which is then skimmed from the liquid surface by a simple collection trough. Gas and a small volume of treated water are continuously recycled from the degassing chamber into the treatment cells. The skim cycles are automatically initiated by a timer and the cycle interval, duration and level setpoints are all user-selectable and can be changed without interrupting operation or entering the vessel. The power requirements of the ISF are very low with the gas induction and mixing in the flotation cells being provided by a simple recirculating pump. WATER

OverviewThe WEMCO® ISF® (Induced Static Flotation) System is a leading technology for environmentally safe treatment of secondary produced waters. The ISF system is a simple, hydraulically operated gas flotation machine that delivers efficient oil/water separation with complete process containment. Effective oil recovery and water treatment are achieved simply and economically, with operator and environmental safety ensured by the completely enclosed flotation process. Units are available in either
the horizontal standard four cell or vertical UNICEL® design which is well-suited for locations where space restrictions require a small footprint.
Operating Principle and Key FeaturesStreamlined for simple, efficient operation and maintenance, each ISF machine consists of a cylindrical vessel partitioned into several major components: floating, degassing, optional skim storage compartments, a recirculation pump and piping and a liquid level control system. All equipment is skid mounted for rapid installation and start-up.
The ISF is an induced gas flotation system through which a high-velocity stream of recycled clarified water enters the cells containing influent water through eductor nozzles in the bottom of the vessel. This induces a recirculating flow of air or gas from the vessel freeboard into the process water, and a unique eductor arrangement distributes small gas bubbles uniformly throughout the cell volume.

The power requirements of the ISF are very low with the gas induction and mixing in the flotation cells being provided by a simple recirculating pump.
