Desalination by reverse osmosis

By 2030, almost one half of the world’s population, or four billion people, will be short of fresh water. Only 3% of the water on Earth by volume is fresh. Therefore, salt water is an indispensable natural resource for the production of drinking water. Are you looking for innovative solutions to secure the long-term supply of drinking water? Desalination by reverse osmosis meets the demands for economic and environmental performance.

Our technologies

Products and services delivering technical and economic solutions adapted to your needs

Seadaf ™ - A compact clarification solution

This compact clarification solution by fast flotation of salt water replaces the first filter stage. It is well adapted to water subject to occasional peaks of suspended solids and algal bloom.


Seaclean™ - A pretreatment that improves the performance of reverse osmosis

This pretreatment technology that uses dual-media filtration (anthracite and sand) is well suited to desalination plants of all sizes. It improves the performance of the reverse osmosis, increases the lifespan of the reverse osmosis membranes, reduces the need for washing equipment and cuts water losses.


Ultramarine™ Smartrack™ - A universal rack for interchangeable ultrafiltration modules

This metal rack can receive different brands of ultrafiltration membrane modules for pretreatment. It is an industry-standard system that shortens deployment cycles and reduces the cost of replacing the membranes.
