SWC - Hydranautics - #1

SWC - Seawater Composite Membrane Elements

Hydranautics is the world leader in seawater desalination, producing over 500 million gallons per day (2 million m3/d) of purified water. With more installed capacity than any other competitor, the SWC membrane provides unparalled and consistent operating performance.

SWC elements are available from Hydranautics in both 4-inch and 8-inch diameters by 40-inch long spiral wound configurations for all desalination applications. Smaller diameter seawater elements are also available from Hydranautics' licensed manufacturer Oltremare, located in Fano, Italy. The high productivity SWC elements offer the highest levels of salt rejection with a consistently pure end product. The patented membrane formulations have been designed to accommodate varying levels of seawater salinities worldwide with reliable field-proven performance. The SWC5, for example, is state-of-the-art for seawater desalination providing the best combination of energy savings and high rejection. The SWC5 can be used in combination with the ESPA-B in a second pass to achieve stringent boron requirements. This combination of membrane element types is one example of our Integrated Membrane Solution® (IMS) which combines a range of RO, NF, UF and MF membrane technologies to achieve the most comprehen­sive, effective, low-cost results in the industry.
