Osmos project objetives

The overall objective mentioned, is based on the following specific objectives: 

  • Development of forward osmosis process. It will be necessary to research and define of membrane type to be used, as well as extracting agent.

  • Development of an ultrafiltration process. It will be capable of recovering, on the one hand, the desalinated water, and secondly the extracting agent used in the process of forward osmosis.

Depending on the results obtained along the evolution of the project, the consortium may achieve other challenges, along the same lines:

  • The combined process of forward osmosis - ultrafiltration could also be applied to the concentration of residual brine from desalination facilities using conventional processes, such as reverse osmosis with special mention to desalination indoor plants . In this case it would also be necessary to research a hydrophilic polymer to remove water from the brine.

  • Another possible application of the forward osmosis could be the tertiary treatment of municipal and industrial wastewater for reusing it. Due to forward osmosis process doesn’t apply pressure it has the advantage that the membranes suffer less fouling (principal advantage over the process of reverse osmosis).

According to these objectives, the consortium will achieve a set of innovations, as: 

  • To develop a new desalination system based on a forward osmosis process, that today it is not used in any plant, either in Spain or outside Spain. It could lead a revolution in the field of water desalination, due not only to real energy savings that would result in this new process, but also to the provision of fresh water for use in irrigating fields or even human consumption. 

  • Furthermore, this process of forward osmosis and ultrafiltration would be easy adapted for other water treatments as tertiary wastewater treatment.
