• Max. SDI (15 min): 5.0
• Max. Chlorine Concentration: < 0.1 mg/L

Mechanical / hydraulic

• Element Model: RE4040-BE
• Dimensions:
  • A: 40.0 inch (1,016 mm)
  • B: 3.9 inch (99.0 mm)
  • C: 0.75 inch (19.1 mm)
  • D/E: 1.05 inch (26.7 mm)
• Inter-Connector Part Number: SWA01050
• Brine Seal Part Number: SWA01046
• Each membrane element is supplied with one interconnector (coupler) and four O-rings.
• All RE4040 elements fit nominal 4.0 inch (101.6 mm) I.D. pressure vessels.
• The element shell is made of Fiber Reinforced Plastic (FRP).

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.
• For WET-TYPE elements, a preservative solution (1% sodium metabisulfite solution) is added to prohibit microorganism growth.
• Permeate from the first hour of operation should be discarded.
• Stabilized salt rejection is generally achieved within 1–48 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; use of incompatible chemicals may void the 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.
• Be aware of glass fiber strands from the FRP shell and use safety equipment.

Certifications

• Certified to NSF/ANSI/CAN 61.
