Mechanical / Hydraulic

• Dimensions:
  • A = 40.0 inch (1,016 mm)
  • B = 8.0 inch (203 mm)
  • C = 1.12 inch (28 mm)
• All RE8040 elements fit nominal 8.0 inch (203 mm) I.D. pressure vessels.
• Each membrane element comes with one brine seal, one interconnector (coupler), and two o-rings.

General Handling Procedures

• Elements must be kept dry at room temperature (7–32 °C; 40–95 °F) and should not be stored in direct sunlight.
• If the polyethylene bag is damaged, a new preservative solution (sodium bisulfite) must be added and air-tight sealed to prevent drying and biological growth.
• 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. The standard storage solution contains 1% by weight sodium bisulfite or sodium metabisulfite (food grade). For short-term storage (i.e., one week or less), 1% by weight sodium metabisulfite solution is adequate for preventing biological growth.
• 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. Use of such chemicals may void the element limited warranty.
• Permeate pressure must always be equal to or less than the feed/concentrate pressure. Damage caused by permeate back pressure voids the element limited warranty.
