Product Description
AXEON Ultra Low Energy HF5-Series Reverse Osmosis Membranes are manufactured using the industry's leading membrane film technology. These membranes offer reliability, high performance and deliver consistent results. They provide increased production, high rejection rates and ultra low energy consumption by operating at low applied pressures.
AXEON HF5-Series Membranes are the only elements on the market that operate at a pressure of only 80 psi - which equals more energy savings. AXEON HF5-Series Membranes are available in all standard 4-inch commercial sizes and feature a protective tape wound exterior. AXEON HF5-Series Membranes are the best choice to counter the negative effects of cold temperatures on reverse osmosis production. All elements are shipped dry for an indefinite shelf life and easier handling. AXEON HF5-Series Membrane Elements are 100% vacuum integrity tested.

This membrane has no equivilant product at the moment from any of the other membrane manufacturers ranges. This membrane will replace any of the membranes listed below:
FilmTec XLE-4040
GE Desal AK90
Hydranautics ESPA4-4040
AXEON HF4-4040
SPECTRUM SRO-4040-2500-LE
These are a popular membrane with window cleaners and car washes however this membrane is designed to be run under set conditions in an engineered reverse osmosis system. Most systems in the window cleaning industry are not run within the manufacturers specifications and as such no warranty can be enforced and are run at the operators own risk.
Things you can do to reduce your chances of damaging the membrane
If running with an engineered RO system designed inline with the membrane manufacturers specifications refer to your installation manual.
Change your pre-filters. It is important to begin a new membrane installation with fresh filters. Blocked or exhausted filters will have a detrimental effect on your membranes performance.
Ensure the membrane housing is clean and sterile before installing a new membrane.
Ensure the membrane is correctly installed (see membrane installation sheet).
The membrane can only be installed one way, any deviation from the correct method will twist the brine seal and stop the membrane operating correctly.
When the membrane is first installed run at tap pressure with the waste fully open. This is to wet out the membrane and flush out any preservative. Never use a pump on a newly installed membrane, it must be wetted out first or it may damage the membrane (hydraulic shock).
After the membrane is wetted out, if you have a pump switch it on now ensuring the waste valve (throttle) is still fully open.
Start with the waste fully open, then close it a little and take a TDS reading. Then close it a little more and take another TDS reading, repeat this procedure. You should observe the inlet pressure increasing and the permeate (product) water TDS decreasing. At some point you will find the at TDS will rise which indicates you've just passed the "sweet spot" so readjust to previous position. The "sweet spot" is the position where the membrane gives you the lowest TDS and balances back pressure with adequate waste water. This is typically at about 80% waste to 20% permeate (product) water if using a single membrane.
NEVER CLOSE THE WASTE WATER VALVE (THROTTLE) OR REDUCE THE WASTE TOO MUCH - IT WILL RUPTURE THE MEMBRANE.
Notes on pump selection.
Ensure the pump you choose not only delivers an adequate pressure but also an adequate flow rate. This will typcially be a multistage centrifugal pump or rotary vane pump.
Ensure the water is delivered at a constant pressure and flow rate. There should be no "pulsing", sudden pressure drops or pressure increases as this will damage the membrane. An example of this is if the pump uses a pressure vessel, this should be avoided or reciprocating pumps.
