Additional 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.
  • To ease installation, it is recommended to use a lubricant safe for indirect water contact on all seals. Potential options include water, glycerin based lubricants, and MOLYKOTE¬ģ 111 Compound.
  • Rotate the element about a quarter turn to ease installation and removal of the element. Ensure good interface between the o-rings and brine seal with their connection surfaces.
  • 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.

Service

Reverse Osmosis Membranes, can be replaced every 5* years. However to prevent oxidation on thin-film RO membranes, the feed water must be dechlorinated. Most membranes will have some chlorine tolerance before there is an observable decrease in salt rejection. Chlorine on the membrane can be discovered by an initial loss of membrane flux followed by an increase in membrane flux and salt passage.

Reverse Osmosis Membranes

Reverse Osmosis Membrane. The Reverse Osmosis Membrane is a ‚Äčthin membrane with pores small enough to pass pure water through while rejecting larger molecules such as dissolved salts (ions) and other impurities such as bacteria.

Membranes are easily damaged by chlorine in the feed water. Chlorine damage to the membrane can lead to lower salt rejection and poor-quality permeate, which in turn could result in costly membrane replacement and down-time.

Reverse Osmosis water filtration systems that incorporate carbon block filters are an effective way to remove up to 98% of chlorine in water. Carbon block prefilters will not only remove chlorine in water, but also protect delicate RO membranes that can be damaged by contact with chlorine.
