Produced Water Primary Treatment

Produced water from the crude oil separation train typically contains 500 - 2000 mg/l of free oil. The first step in produced water processing is to reduce the solids content, followed by the reduction of the oil content to below 500 mg/l by gravity separation using desanding, liquid-liquid separation, skimming or corrugated plate interceptors. Our equipment targets specific oil droplet size, producing smaller and smaller droplets as the liquid progresses through the treatment process.


Desanders offer high efficiency removal of solids from processed water, to protect downstream equipment.


Liquid-liquid hydrocyclones are primary separation units that use centrifugal force to separate fluids that cannot be easily blended.
