Aquaporin Inside Clear Plus 4040

Summary

Product Identification

The Aquaporin Inside® CLEAR series consists of biomimetic brackish water reverse osmosis products. They incorporate aquaporin water channels into membranes to enable fast, energy-efficient, and natural water filtration.

CLEAR Plus reverse osmosis elements are low-energy products designed to balance energy savings with permeate water quality. They are suitable for municipal drinking water, industrial process water production, and wastewater reuse applications where the feed water has low-to-medium salinity.

Key features include:

• Best in-class permeate flow rate
• Delivery of great permeate quality at low pressure
• Reliable performance in long-term operation

Product Specifications

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 minutes of operation. Flow rates for individual elements may vary but will be no more than 15% below the value shown.

Important Notes

• Permeate from the first hour of operation should be discarded. Do not use this initial permeate for consumption.
• Keep elements moist at all times after initial wetting.
• For details on element handling, storage, and preservation, refer to the relevant guide.
• For optimal and damage-free operation, refer to the "Industrial Aquaporin Inside® RO Membrane Element User Manual".
