• C (Inner Diameter): 1.12 inch (28.5 mm)
• Weight: 15kg
• Inter-Connector Part Number: SWA01049
• Brine Seal Part Number: SWA01043

General Handling Procedures

• Elements must be kept dry at room temperature (7–32°C; 40–95°F) and not stored in direct sunlight.
• For WET-TYPE elements, a 1% sodium metabisulfite solution is added as a preservative.
• 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 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.
• Be aware of glass fiber strands from the FRP element shell and use safety equipment during handling.
