Applications

• Industrial
• Municipal
• Semiconductor

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 preservative solution is added to prohibit microorganism growth.
• 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, as 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.
• Be aware of glass fiber strands from the FRP shell and use safety equipment.
