Available technologies

Hydroclones

Uses hydrodynamic cyclonic effect to generate high g-forces to separate phases efficiently in a very short residence time.
High oil removal efficiency, compact equipment, in-sensitive to external motion
Requires high pressure drop for efficient operation, requires steady inlet flow/conditions

Gas Floatation methods

Various technologies available to impart fine gas bubbles into water to lift out oil/solid particles
High oil removal efficiency, can handle wide range/ fluctuating inlet conc’s
Generally requires gas supply, required chemicals for enhanced performance

Filtration methods

Various filtration technologies available from simple cartridge type, activated carbon, media bed (anthracite etc.) and Walnut Shell
Very high oil removal efficiency, can handle wide range/ fluctuating inlet concentrations
Problem with media disposal or regeneration, large complex systems for large flow rates

Gravity / API Separators

Original treatment method
Large tank with high res. Time
Simple design, no moving parts, relatively cheap.
Large vessels, ineffective with small oil droplets, requires long res. Time to get efficient separation
