General handling procedures

• Elements are vacuum leak tested using the CSM integrity test.
• Elements can be supplied as dry or wet-type.
• Wet-tested elements are soaked in a preservative solution (1.0% food grade SBS) and vacuum sealed in a poly bag.
• All elements are individually boxed.
• Elements contained in the 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, a preservative solution (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 such 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.
