The reverse osmosis membranes used in seawater desalination are susceptible to biological  fouling and plugging with fine silt. Therefore seawater desalination requires extensive pretreatment.
Conventional treatment systems are either unable to meet these quality standards or multiple barriers are required which require a larger footprint and investment.

Norit X-Flow’s hollow fibre UF membrane will remove all fine silt and turbidity and will screen microbiology. This Norit X-Flow UF membrane will provide a simple solution that will produce water that meets the highest standards for SDI,  turbidity and micro biology.

Norit X-Flow is the first membrane supplier to supply a membrane specifically designed to pretreat seawater:

• SEAGUARD - Multiple membranes (up to 4) installed in horizontal membrane housings.
• The membrane housings are made of corrosion resistant GRP and have been designed for UF operation (high flow and low pressure).
• Norit X-Flow has standardized skid designs available for installation of the SEAGUARD membranes. These skids are being constructed of corrosion resistant materials, suitable for operation in high salinity environments.

The Norit X-Flow SEAGUARD membrane modules are being produced with ISO 9000 certification.
