  • Each membrane element is supplied with one interconnector (coupler) and four O-rings.
  • All RE8040 elements fit nominal 8.0 inch (203.2 mm) I.D. pressure vessels.
  • The element shell is FRP (Fiber Reinforced Plastic). Use safety equipment due to potential glass fiber strands.

General handling procedures

• Elements must be kept dry at room temperature (7–32°C; 40–95°F) and not stored in direct sunlight.
• For WET-TYPE elements, a 1% sodium metabisulfite solution is added as a preservative to prohibit microorganism growth.
• Permeate from the first hour of operation should be discarded.
• Stabilized salt rejection is generally achieved within 1 to 48 hours of continuous use.
• 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, as incompatible 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.

Certifications

• Certified to NSF/ANSI/CAN 61
