The SWC5-LD 4040 Seawater Reverse Osmosis membrane from Nitto Denko Corporation – Hydranautics combines the best of the seawater desalination technology with the cutting edge of the low fouling LD Technology™. The SWC5-LD gives you the highest flow rates, highest ion rejection and the lowest energy consumption combined with reduced biological and colloidal fouling. The Hydranautics SWC5-LD is the most suitable membrane for desalination applications for conventional as well as hybrid plants. The SWC5-LD offers the same performance as the SWC5 with additional low fouling characteristics and superior salt and boron rejection with low operating pressures.
