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.
