EAST KILBRIDE, UK -- MODEC has contracted VWS Westgarth and VWS Brazil for a seawater treatment package for a development project offshore Brazil.

The package will be supplied as a single-lift module comprising coarse strainers, media filtration pre-treatment, vacuum de-aeration, and sulfate removal process (SRP) systems. Water throughput capacity of the equipment will be 24,000 cu m/day (150,972 b/d).

VWS Westgarth’s offices close to Glasgow will manage engineering. Sister company VWS Brazil based in Rio de Janeiro will provide local engineering support, project management, local procurement, and module fabrication supervision.

The SRP system is designed to remove sulfates and other divalent hardness ions from injection water using Dow/Filmtec SR90-440i membranes to improve oil recovery. Removal of these ions lessens the likelihood of barium sulfate and strontium sulfate scale build-up in the reservoir. The system should also prevent well souring by controlling sulfate-reducing bacteria.
