HFFO14
The Aquaporin Inside® HFFO14 module is designed for Forward Osmosis (FO) applications.
Biomimetic hollow fiber module comprising an active layer of polyamide thin film composite (TFC) with integrated aquaporin Aquaporin Inside® HFFO14 module Aquaporin Inside® Membranes Hollow fiber forward osmosis module proteins. The addition of aquaporin water channels into the rejection layer makes the Aquaporin Inside® FO membrane capable of rejecting difficult contaminants and preserving valuable components. The use of hollow fibers allows for a very high packing density.

a. It is of utmost importance to respect the ranges for the different pH and temperature combinations. If in doubt, contact Aquaporin A/S to assist with a case-specific evaluation.
b. The optimal pre-filtration is application dependent.
c. Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Since oxidation damage is not covered under warranty, Aquaporin A/S recommends removing residual free chlorine by pre-treatment prior to membrane exposure.
d. Refer to cleaning guidelines in the User Manual.

ADDITIONAL INFORMATION
- Module should be operated in vertical position with feed inlet in the top and draw inlet in the bottom.
- It is recommended to rinse the module for 30 min, prior to first use.
- It is advisable to pre-treat the feed solution to remove suspended solids. Particles might damage the fibers and possibly cause a decrease in performance.
- Run feed solution prior to draw solution to avoid osmotic drying of the membrane.
- Do not allow the module to run dry as this will compromise the membrane performance.
- Immediately flush the module on feed side with clean water for ≥ 30 min after use (draw side connections open).
- The module can be stored at room temperature, but preferred storage is at 4 °C.
- Keep out of direct sunlight.
- To prevent biological growth during prolonged system shutdowns, the module should be immersed in a preservative solution. Rinse thoroughly before re-use.
- Keep the module moist at all times after initial wetting.
