The WEMCO® ISF hydraulically induced gas flotation system is a leading technology for environmentally preferred treatment of secondary produced waters. The 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, and the completely enclosed flotation process helps protect operator and environmental safety.

Units are available in either the standard horizontal four-cell unit or the UNICEL Vertical IGF unit design, which is well suited for locations where space restrictions require a small footprint.

Streamlined for simple, efficient operation and maintenance, each ISF system consists of a cylindrical vessel partitioned into several major components: floating, degassing, and optional skim storage compartments; a recirculation pump and piping; and a liquid level control system. All equipment is skid mounted for rapid installation and startup.
