High-quality water will be produced on the FPU through a compact multi-element UF system designed and supplied by Veolia Water Technologies, using DOW IntegraFlo UF elements.
Dow Water & Process Solutions’ UF membrane technology will be used to treat seawater required for reservoir injection. The UF seawater treatment installation will treat 210 000 barrels of seawater per day.
Dow technology will be used as a pretreatment in the Moho Nord FPU water injection system, enabling effective removal of suspended solids and bacteria from seawater. Following pre-treatment by the UF system, the seawater will be fed to the FPU’s Sulphate Removal Unit (SRU), equipped with DOW FILMTEC SR90 elements, prior to injection into the reservoir. The SRU removes the sulphate from the seawater, which prevents reservoir scaling and souring. The water is then injected into the oil bearing reservoir for waterflooding and pressure maintenance.
