Super-Flux RO

GrahamTek Systems prides itself on being a world leader in the Seawater Desalination Industry.

GrahamTek is still today the only company in the world producing a 16" Spirally wound membrane system for Reverse Osmosis of Seawater. The addition of our patented Integrated Flow Distributor on the feed end of the membrane gives our systems a Flux rate of up to 16 GFD (Gallon Flux per day)

Patented Electro Magnetic Devices on our Seawater applications have proven at sites like PSA Singapore, that the use of Magnetic fields in a specific configuration and design, further inhibits scaling and gel layer forming on our membranes. 

Technological innovations offer the only systems available in the world today that inhibit fouling and scaling during operation, eliminating the need for chemicals and achieving higher fluxes than conventional, higher energy reliant RO membrane systems.

The use of energy recovery systems on our desalination plants have significantly reduced overall power consumption, and the latest addition of Pressure Exchange systems now make Desalination of Seawater a very attractive solution.

The PE devices were first sold commercially in 1998. The all-ceramic moving and mating parts of the PE have shown exceptionally low, and even zero wear in high-pressure SWRO brine applications and the material is not susceptible to the pitting and stress corrosion of steel and bronze components in similar applications. The slow rotating PE (1,500 RPM) has proven to be a low maintenance component in commercial desalination plants.

Since the PE transfers energy directly from the brine to the feed without high speed rotating shaft inefficiencies, the PE achieves actual efficiencies of 91 to 95 percent within a broad flow range.

Reduced energy and capital costs mean that for the first time ever it is possible to produce potable water from seawater at a cost below $1 per cubic meter in many locations worldwide.
