Accessories:

• Each membrane element is supplied with one interconnector (coupler) and five O-rings.
• All RE16040 elements fit nominal 16.0 inch (402 mm) I.D. pressure vessels.

General Handling Procedures

• Elements in boxes must be kept dry at room temperature (7–32 °C; 40–95 °F) and not stored in direct sunlight.
• If the polyethylene bag is damaged, a new preservative solution (sodium bisulfite) must be added and air-tight sealed.
• Permeate from the first hour of operation should be discarded to flush out the preservative solution.
• Elements should be immersed in a preservative solution during storage, shipping, and system shutdowns to prevent biological growth and freezing.
  • Standard storage solution: 1% by weight sodium bisulfite or sodium metabisulfite (food grade).
  • For short term storage (one week or less): 1% by weight sodium metabisulfite solution.
• Keep elements moist at all times after initial wetting.
• Avoid excessive pressure and flow spikes.
• Only use chemicals compatible with the membrane elements and components.
• Permeate pressure must always be equal to or less than the feed/concentrate pressure.
