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 unparalleled and consistent operating performance. SWC elements are available from Hydranautics in both 4-inch and 8-inch diameters by 40-inch long spiral wound configuration for all desalination applications. 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 can be used in combination with the ESPAB as second pass to achieve stringent boron requirements. This combination of membrane element types is one example of our Integrated Membrane Solutions® (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.
- Boiler makeup water in power industry.
- Conventional and hybrid desalination plants.
- Boron reduction for agricultural application.
