CSM RE1812-60

Summary

Product identification

This reverse osmosis (RO) membrane element is designed for residential use.

• Model Name: RE1812-60
• Membrane Type: Thin-Film Composite
• Membrane Material: Polyamide (PA)
• Element Configuration: Spiral-Wound, Tape Wrapping
• Certification: Certified to NSF/ANSI 58

Performance Specifications

• Permeate Flow Rate: 80 GPD (303 L/day)
• NaCl Rejection: 98% (Minimum 96%)
• Permeate Flow Rate Variation: ±20%
• Minimum Salt Rejection: 96.0%

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

• NaCl Solution Concentration: 200 mg/L
• Applied Pressure: 60 psig (0.41 MPa)
• Recovery: 15%
• Temperature: 77℉ (25℃)
• pH: 6.5–7.0

Elements can be supplied as dry or wet-type. Wet-tested elements are soaked in a preservative solution (1.0% food grade SBS) and vacuum sealed in a poly bag. All elements are individually boxed.

Dimensions

Operating limits

• Max. Operating Pressure: 150 psi (1.03 MPa)
• Max. Feed Flow Rate: 2 gpm (0.45 m³/hr)
• Max. Operating Temperature: 113℉ (45℃)
• Operating pH Range: 2.0 – 11.0
• Max. Turbidity: 1.0 NTU
• Max. SDI (15 min): 3.0
• Max. Chlorine Concentration: < 0.1 mg/L

General Handling Procedures

• Elements 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 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. Use of 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.
