Register here Sign inAs one of the original licensors for sulfate removal membrane technologies, we have the experience and capability to support our customers through the whole project life cycle. From the initial concept design through to construction, commissioning, and operation.
Our experience includes delivering projects across the globe to installations in Brazil, Gulf of Mexico, North Sea, and Africa. We understand the challenges with equipment design and operation, enabling us to have a non-biased approach to technology selection.
We have a flexible execution model to suit the customer and project requirements such as local content restrictions. We can provide equipment only, skid-based solutions, or fully integrated modules fabricated internally at our Profab facility or externally.
Our skills in conjunction with our Fiber Glass Systems business unit can offer cost efficient, corrosion resistant, and lightweight pressure vessel, piping, and structural solutions utilizing fiberglass.
Our Brownfield Solutions can provide operational support, troubleshooting, and modifications. We have developed a digital platform, the Process Intelligence Manager, which includes unique machine learning features keeping us connected to the technology during operation. The tool facilitates remote troubleshooting and maintenance recommendations which help reduce OPEX and increase uptime.

- Coarse filtration
- Cartridge filters, media filtration, or ultrafiltration
- Sulfate removal using nanofiltration
- Deoxygenation (vacuum tower, compact stripping, membrane deaeration)
- Desalination using reverse osmosis
- Water-injection pumping systems
