CSM RE2812-300

Summary

Product identification

The RE2812-300 is a residential reverse osmosis (RO) element, certified to NSF/ANSI 58.

• Membrane Type: Thin-Film Composite
• Membrane Material: Polyamide (PA)
• Element Configuration: Spiral-Wound, Tape Wrapping
• Elements can be supplied as dry or wet-type. Wet-tested elements are soaked in a 1.0% food grade SBS preservative solution and vacuum sealed. All elements are individually boxed.

Operating limits

• Max. Operating Pressure: 150 psi (1.03 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

Feed water

• Max. Turbidity: 1.0 NTU
• Max. SDI (15 min): 3.0
• Max. Chlorine Concentration: < 0.1 mg/L

Product water

• Permeate Flow Rate: 350 GPD (1,325 L/day)
• NaCl Rejection: 97% (Minimum 95%)

Test Conditions (for stated performance):

• 200 mg/L NaCl solution
• 60 psig (0.41 MPa) applied pressure
• 15% recovery
• 77℉ (25℃)
• pH 6.5–7.0
• Permeate flow rate for each element may vary +25 / -15%.
• Minimum salt rejection is 95.0%.
• All elements are vacuum leak tested using the CSM integrity test.

Mechanical / hydraulic

Dimensions for model RE2812-300:

• A: 0.67 inch (17 mm)
• B: 0.87 inch (22 mm)
• C: 11.73 inch (298 mm)
• D: 0.87 inch (22 mm)
• E: 2.93 inch (74.5 mm)

General Handling Procedures:

• Elements in boxes 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 to prohibit the growth of micro-organisms.
• 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 limited warranty.
