Important Information

• Preservation:
  • Dry membrane elements have no preservation solution and are vacuum-packaged.
  • Wet membrane elements contain 1.0% sodium bisulfite (with 10% propylene glycol antifreeze added in winter) as a preservation solution and are vacuum-packaged.
  • Dry membrane elements must be maintained wet after soaking.
  • Wet membrane elements require preservation solution for long-term storage when not in use.
• Initial Flushing:
  • When first used, flush for 15-25 minutes at low pressure (not suitable for soaking overnight).
  • Subsequently, flush for 60-90 minutes at high pressure (water flow should not be less than 50% of the system design flow).
  • Permeate and concentrated water from the first hour of initial operation must be discharged.
• Chemicals:
  • The addition of any chemicals that may affect the membrane element during storage and operation is prohibited.
• Warranty:
  • The operating limits and guidelines provided are part of the limitations for the three-year warranty on the membrane element.
• Documentation:
  • Refer to the Product Manual for detailed information on installation, commissioning, storage, and transportation.
