Cophase CFU - Compact Flotation Unit

Traditional produced water treatment has usually comprised of hydrocyclones followed by degassing or flotation processes. Increasingly stringent environmental discharge requirements plus the constant pressure to reduce equipment footprint have led to the development of the Compact Flotation Unit (CFU).
Traditional produced water treatment has usually comprised of hydrocyclones followed by degassing or flotation processes. Increasingly stringent environmental discharge requirements plus the constant pressure to reduce equipment footprint have led to the development of the Compact Flotation Unit (CFU). Veolia has taken this process forward to the next level with the Cophase CFU.
Benefits of CFU:
- Highly tolerant of typical FPSO motion
- Self regulating oil skimmer eliminates gas and reduces water in the reject stream
- Skimmed flow minimized to <1% of total flow
- One minute retention time reduces vessel size and weight
- No motor or pump consuming power
- Turndown performance is consistent
- 100% of the inlet flow passes through the LoHead eductors ensuring excellent gas/liquid contact and superior separation performance
- No rotating parts to maintain
- Designed for high flow rate
- No need for pressurized water or gas, in most cases no gas consumption at all
