CSM RE1812-CE50

Summary

Product identification

• Model Name: RE1812-CE50
• Features: Innovative chlorine resistant RO element for residential use
• Membrane type: Thin-Film Composite
• Membrane material: Polyamide (PA)
• Element configuration: Spiral-Wound, Tape Wrapping

Performance Specifications

The stated product performance is based on data taken after 30 minutes of operation at the following test conditions:

• Permeate Flow Rate: 50 GPD (189 L/day)
• Salt Rejection: 98%
• Test Conditions:
  • 200 mg/L NaCl solution
  • 60 psig (0.41 MPa) applied pressure
  • 15% recovery
  • 77 °F (25 °C)
  • pH 6.5–7.0

Note: Permeate flow rate for each element may vary but will be no more than 15%.

Operating Limits

• Max. Operating Pressure: 125 psi (0.86 MPa)
• Max. Feed Flow Rate: 2 gpm (0.45 m³/hr)
• Max. Operating Temperature: 113 °F (45 °C)
• Operating pH Range: 2.0–11.0
• Max. Turbidity: 1.0 NTU
• Max. SDI (15 min): 5.0
• Max. Chlorine Concentration: < 0.1 mg/L

Mechanical / hydraulic

Dimensions for model RE1812-CE50 (all measurements in inches, with millimeters in parentheses):

• A: 0.67 (17mm)
• B: 0.87 (22mm)
• C: 11.73 (298mm)
• D: 0.98 (25mm)
• E: 1.77 (45mm)

General Handling Procedures

• Elements contained in the boxes 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.
• 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 or less than the feed/concentrate pressure. Damage caused by permeate back pressure voids the element limited warranty.
