Product water

• Permeate flow rate: 36,000 GPD (136.1 m³/day)
• Nominal salt rejection: 99.6%
• Minimum salt rejection: 99.5%

Note: Stated product performance is based on 30 minutes of operation at 1,500 mg/L NaCl solution, 150 psig (1.0 MPa) applied pressure, 15% recovery, 77 °F (25 °C), and pH 6.5–7.0. Permeate flow rate for each element may vary but will be no more than 15% from stated.

Mechanical / hydraulic

• Dimensions:
  • A: 40.0 inch (1,016 mm)
  • B: 16.0 inch (402 mm)
  • C: 3.0 inch (77 mm)
• Weight: 60 kg
• Effective membrane area: 1,600 ft² (148.6 m²)

All RE16040 elements fit nominal 16.0 inch (402 mm) I.D. pressure vessels. Each membrane element is supplied with one interconnector (coupler) and five o-rings. Elements are vacuum sealed in a polyethylene bag containing 1.0% SBS (sodium bisulfite) solution and individually packaged in a cardboard box.

General Handling Procedures

• Elements in boxes must be kept dry at room temperature (7–32 °C; 40–95 °F) and out of 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 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 (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. 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.
