ABSTRACT:
Methods and apparatus for demulsifying oil in water by dilution and impact, and for separation of the oil and suspended solids by dissolved gas floatation, are described. A produced water treating system is also described. The produced water treating system may include a dissolved gas floatation clarifier system, an oil demulsification system, and a separation system. A demulsification subsystem is also described. The apparatus may include a liquid-liquid fluid mixer and a gas generator.
