Applications

• Food
• Municipal
• Industrial

General Handling Procedures

• 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.
• 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 or less than the feed/concentrate pressure. Damage caused by permeate back pressure voids the element limited warranty.
• Be aware of glass fiber strands and use safety equipment when handling elements with FRP shells.

Certifications

• Certified to NSF/ANSI/CAN 61
