Produced Water

Produced water is naturally occurring water that comes out of the reservoir as a byproduct of oil and gas production. It can contain a range of contaminants that need to be treated either for reinjection or for safe discharge to the sea. Veolia offers an integrated and optimised process solution that meets stringent discharge requirements.

The constituents of produced water are many and varied, with the majority of substances being: Water, hydrocarbons, production chemicals and solids, both suspended and dissolved.  These contaminants need to be treated to enable the produced water to be either injected or safely disposed of according to local environmental regulations.

Veolia has developed an innovative range of produced water technologies that in combination are able to treat produced water to be safely discharged to the stringent environmental discharge requirements and achieve the high operational reliability demanded for offshore use.


The desanding hydrocyclone liner has been designed to efficiently remove damaging levels of the solid particles such as sand, scales and corrosion products present in the produced water stream




The purpose of the STREAMLINER™ de-oiling hydrocyclone is to separate free oil from produced water prior to discharge or injection

Cophase - Compact Flotation Unit

The CophaseTM CFU operates by combining the well established principles of gas flotation, oil droplet coalescence and centrifugal separation into a single process step
