One of the most used desalination technologies is reverse osmosis. Prior to the process of separating water from salts and minerals, sea or brackish water requires the removal of larger particles for the proper functioning of reverse osmosis membranes. Our sand filters facilitate the removal of these suspended solids to prevent saturation of the membranes.

In addition, after reverse osmosis, water must be remineralized by calcite beds that allow to increase the alkalinity and hardness of desalinated water and reduce its corrosivity in order to be suitable for human consumption, domestic, industrial or irrigation use .
