Product water

The stated product performance is based on data taken after 30 minutes of operation at the following test conditions: 2,000 mg/L NaCl solution at 225 psig (1.5 MPa) applied pressure, 15% recovery, 77 °F (25 °C), and pH 6.5–7.0.

• Permeate flow rate: 41,000 GPD (155 m³/day)
• Nominal salt rejection: 99.7%
• Minimum salt rejection: 99.4%
• Permeate flow rate for each element may vary but will be no more than 15%.

Mechanical / hydraulic

• Effective membrane area: 1,600 ft² (148.6 m²)
• Dimensions (RE 16040-BE):
  • A: 40.0 inch (1,016 mm)
  • B: 16.0 inch (402 mm)
  • C: 3.0 inch (77 mm)
• Weight: 60 kg
• All RE16040 elements fit nominal 16.0 inch (402 mm) I.D. pressure vessels.

Handling Procedures

• Elements are vacuum sealed in a polyethylene bag containing 1.0% SBS (sodium bisulfite) solution and individually packaged in a cardboard box.
• Elements 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.
• 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. The standard storage solution contains 1% by weight sodium bisulfite or sodium metabisulfite (food grade). For short-term storage (one week or less), 1% by weight sodium metabisulfite solution is adequate.
• 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.
• 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.
