With good wear and chemical degradation resistance, 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.

Notes for RO Membrane 8040
Permeate flow for individual elements may vary ±15 percent from the value specifed.
Active membrane area guaranteed ±4%.
Stabilized salt rejection is generally achieved within 24-48 hours of continuous use; depending upon feedwater characteristics and operating conditions.
◆ 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 RO Membrane 8040 elements moist at all times after initial wetting.
◆ To prevent biological growth during prolonged system shutdowns, it is recommended that RO Membrane 8040 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.
