Water Desalination Systems

PURETEC seawater desalination (SD) systems are designed for desalinating seawater. They are usually designed for an operation pressure of 5 to 80 bars. Special materials, such as Super Duplex A890 are used for all high pressure pipes and instruments.

The systems are skid mounted, containerized according demand, pre-wired and tested. They address a wide range of requirements and can be customized to meet specific needs.
