Freshwater generators by evaporation

El generador de agua Fontemar® está diseñado para transformar agua salada del mar en agua dulce, apta para el uso humano e industrial. Este equipo puede ir tanto a bordo de los buques como en instalaciones de tierra.

El equipo trabaja bajo el principio de destilación en vacío. En el interior de la carcasa el agua salada hierve a baja temperatura (debido al vacío) y el vapor de agua producido, al elevarse, atraviesa el separador y llega al condensador. El agua generada, después de la condensación, es enviada a través de una bomba al tanque almacén.

The Fontemar® water generator is designed to transform sea salt water into fresh water, suitable for human and industrial use. This equipment can be used both on board ships and in shore installations.

The unit works on the principle of vacuum distillation. Inside the casing, the salt water boils at a low temperature (due to the vacuum) and the water vapour produced, on rising, passes through the separator and reaches the condenser. The water generated, after condensation, is sent through a pump to the storage tank.

Freshwater generators by reverse osmosis

El equipo de ósmosis inversa Osmomar® está diseñado para trabajar tanto en instalaciones marinas como terrestres. Su funcionamiento se basa en el proceso natural de ósmosis que se produce en los seres vivos, por el cual dos soluciones de diferente salinidad, puestas en contacto a través de una membrana semipermeable, tienden a igualar sus concentraciones, quedando las sales retenidas en la membrana, permitiendo así el paso del agua sin salinidad.

En la ósmosis inversa, sólo una parte del flujo de alimentación atraviesa la membrana, constituyendo la producción, mientras que el resto se elimina sin atravesar la membrana, constituyendo el rechazo.

The Osmomar® reverse osmosis equipment is designed to work in both marine and land-based installations. Its operation is based on the natural process of osmosis that occurs in living beings, by which two solutions of different salinity, placed in contact through a semi-permeable membrane, tend to equalise their concentrations, with the salts being retained in the membrane, thus allowing the passage of water without salinity.

In reverse osmosis, only a part of the feed flow passes through the membrane, constituting the production, while the rest is removed without passing through the membrane, constituting the rejection.
