  • All RE8040 elements fit nominal 8.0 inch (203.2 mm) I.D. pressure vessels.
  • Each membrane element is supplied with one interconnector (coupler) and four O-rings.
• Component Part Numbers:
  • Inter-Connector: SWA01049
  • Brine Seal: SWA01043
• Element Shell: FRP (Fiber Reinforced Plastic).

General Handling Procedures and Warnings

• Elements contained in boxes must be kept dry at room temperature (7–32°C; 40–95°F) and should not be stored in direct sunlight.
• For WET-TYPE elements, a preservative solution (1% sodium metabisulfite solution) is added to prohibit the growth of micro-organisms.
• Permeate from the first hour of operation should be discarded.
• 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.
• The element shell is FRP (Fiber Reinforced Plastic). Be aware of glass fiber strands and use safety equipment.
