Summary
Product Identification
The Aquaporin Inside® CLEAR series features biomimetic brackish water reverse osmosis products. The Aquaporin Inside® technology incorporates aquaporin water channels into membranes for fast, energy-efficient, and natural water filtration.
CLEAR Classic reverse osmosis elements are brackish water membranes offering a combination of high rejection and durability for challenging water conditions. They are suitable for municipal water treatment, industrial demineralization, and wastewater recycling applications requiring stringent permeate quality.
Product Features:
- Brackish Water Reverse Osmosis Elements
- Industry-standard matching flux and rejection
- Enhanced fouling resistance
- Reliable performance in long-term operation
Product Specifications
The stated product performances are tested at 25 °C (77 °F), 15% recovery, pH 7-8. Permeate flow rates and rejections are stated after a minimum of 60 min operation. Flow rates for individual elements may vary but will be no more than 15% below the value shown.

Additional Information
- Permeate from the first hour of operation should be discarded and not used for consumption.
- Elements must be kept moist at all times after initial wetting.
- For details on element handling, storage, and preservation, refer to the "Handling, Storage, and Preservation of Industrial Aquaporin Inside® RO Membrane Elements" guide.
- For optimal operation and to ensure damage-free operation, refer to the "Industrial Aquaporin Inside® RO Membrane Element User Manual".
- The presence of free chlorine and other oxidizing agents can cause premature membrane failure. Oxidation damage is not covered under warranty, and Aquaporin A/S recommends removing residual free chlorine by pretreatment prior to membrane exposure.
- This product may be subject to drinking water application restrictions in some countries; please check the application status before use and sale.
