SWC5-LD Hydranautics Nitto 9,000 GPD at 800 PSI 8 x 40 inch Membranes
PLEASE REFERENCE TABLE BELOW
⚓ Hydranautics SWC5-LD Seawater RO Membrane
The Hydranautics SWC5-LD is an advanced 8-inch seawater reverse osmosis (RO) element engineered for maximum salt rejection and high-efficiency desalination. As part of the SWC (Sea Water Composite) series, it is specifically designed to treat high-salinity feedwater while delivering ultra-pure permeate. The "LD" designation indicates the integration of Low Differential technology, featuring a specialized feed spacer that reduces colloidal fouling and minimizes the pressure drop across the element, leading to more stable long-term performance and reduced maintenance.
Utilizing a high-rejection composite polyamide membrane, the SWC5-LD is an ideal solution for municipal desalination plants, industrial process water systems, and offshore applications that require the removal of difficult ions like boron. Its design prioritizes both water quality and energy efficiency, allowing for high productivity even in challenging seawater conditions. With an active surface area of 400 square feet, this element provides a permeate flow rate of 9,000 gallons per day and achieves a world-class stabilized salt rejection of 99.8%.
