Within this project, memsys realized together with partner company ABENGOA a sea water desalination system using the retentate/concentrate of an onsite R.O. desalination system.

Following tasks have been addressed:

• Further concentration of R.O. brine, combined with Ultrafiltration
• Optimized energy efficiency of overall system
• Close to ZLD disposal and increased fresh water recovery

The system shall enables an efficient use of the implemented sea water and targets on an overall recovery ration of more than 80%. This creates a concentrate that is close to saturation levels and would be a good preparation for ZLD operation of the overall system.

At the same time, energy efficiency is a major issue, and the implemented technologies target on an overall electricity demand of the system of less than 3.5 kWh/m³.

The implemented memsys MD system has been recently taken into operation and will be finally commissioned after system fine tuning in October 2016.
