CSM UE1812

Summary

Product identification

• Type: UF elements for residential use
• Membrane type: Thin-Film Composite
• Membrane material: Polysulfone (PSF)
• Element configuration: Spiral-Wound, Tape Wrapping

Specifications

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

• Pure water (2 MΩ) at 20 psig applied pressure
• 100% recovery
• 77 °F (25 °C)

Additional notes:

• Permeate flow rate for each element may vary but will be no more than 15%.
• Dry type elements are vacuum leak tested using the San Diego Protocol.
• Dry elements are packaged in a polyethylene bag.
• Wet elements are packaged in a polyethylene bag containing SB(4g/L) + HCl(0.51g/L) solution.

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

Mechanical / Hydraulic

Dimensions (All measurements are in inches)

Certifications

• Models UE1810 and UE2010 are tested and certified under NSF/ANSI standard 58, material requirement only.
• Model UE1812 is excluded from this certification.

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.
