Usage Guidelines

Installation and Operation

• Ensure proper pre-treatment to protect the membrane from fouling, scaling, and physical damage.
• Operate within specified pressure and pH ranges for optimal performance.
• Monitor system parameters such as pressure drop, permeate flow, and salt rejection.

Cleaning and Maintenance

• Perform chemical cleaning when normalized permeate flow decreases by 10%, or salt rejection decreases by 5%.
• Use compatible cleaning chemicals with a pH range of 2–11.

Packaging and Storage

• Packaging:
  • Individually wrapped in a protective polyethylene bag with desiccant inside a cardboard box.
• Storage Instructions:
  • Store in a cool, dry place away from direct sunlight.
  • Keep hydrated; do not allow the membrane to dry out during storage or after first use.

Safety and Compliance

• Certifications: ISO 9001, NSF/ANSI Standard 58 compliant for potable water applications.
• Handling Precautions:
  • Handle carefully to avoid physical damage to the membrane.
  • Use personal protective equipment during installation and cleaning procedures.

Warranty

• Coverage: 12-month limited warranty against manufacturing defects, provided operating conditions are met.
