SW Series -Seawater Desalination RO Membranes UC SW-8040-400XHR

UltraClean SW series are high-end RO membranes featuring a supporting layer with high compression resistance, thick and dense flawless thin film layer. It has good wear and chemical degradation resistance. 

Product Description

The membrane element does not need postprocessing during the manufacturing. It tolerates a wide range of pH, which enables more efficient and rougher cleaning using regular acid and base, therefore it has high cleaning efficiency. The membrane system can operate in long term under lower pressure due to thorough cleaning, therefore the membrane performs better during its service life. It can significantly reduce operation costs, and bring the best long-term economy to the seawater desalination system.

With high salt rejection rate, Seawater Desalination RO Membranes SW-8040-400XHR is engineered specifically for seawater, high salinity water, and concentrated brackish water with the total salt content exceeds 10,000ppm. UC SW series membranes excel in rejection rate, permeate flow rate, compression resistance, fouling resistance, and membrane performance consistency.

Performance Specification


Flux and rejection rate is based on the following standard test conditions: 5.5 MPa (800 psi) pressure, 77°F  (25°C), 32000 ppm NaCl solution and pH 8 for feedwater, and 8% recovery.

Important Information

▲ It is recommended that systems using these elements rinse the elements for 24 hours, prior to first use, to meet NSF/ANSI 58 Standard.

▲ The first full tank of permeate must be discarded. Do not use this initial permeate for drinking water or food preparation.

▲ Keep elements moist at all times after initial wetting.

▲ To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution. Rinse out the preservative before use.

▲ The membrane shows some resistance to short-term attack by chlorine (hypochlorite). Continuous exposure, however, may damage the membrane and should be avoided.
