Description:

AXEON HF5 – Series Ultra Low Energy Membrane Elements utilize AXEON’s innovative and proprietary HF5 Technology™ for increased production. With operating pressures as low as 80 psi, HF5 membranes provide maximum efficiency savings when compared to extra low energy membranes.

Benefits:

  • - All Industry Standard Sizes
  • - Ultra Low Energy with High Flow Rates
  • - Improved RO System Performance
  • - Superior Quality and Cost Savings
  • - Individually Inspected, Qualified and Vacuum Tested
  • - Private Labeling and Customization Available

AXEON HF5 – Series Membrane Elements are the only elements on the market that operate at a pressure of only 80 psi. AXEON HF5 – Series Membrane Elements are available in all standard 2.5 – inch and 4 – inch commercial sizes and feature a tape – wound exterior. AXEON HF5 – Series Membrane Elements are the best choice to counter the negative effects of cold water temperatures on reverse osmosis production. All elements are shipped dry for an indefinite shelf life, easier handling, and a lighter shipping weight. AXEON HF5 – Series Membrane Elements are 100% vacuum integrity tested and may also be ordered as individually wet tested.

Proper start – up of reverse osmosis water treatment systems is essential to prepare the membranes for operating service and to prevent membrane damage due to overfeeding or hydraulic shock. Before initiating system start – up procedures, membrane pretreatment, loading of the membrane elements, instrument calibration and other system checks should be completed.

Avoid any abrupt pressure or cross – flow variations on the spiral elements during start – up, shutdown, cleaning or other sequences to prevent possible membrane damage. During start – up, a gradual change from a standstill to operating state is recommended as follows:

  • Feed pressure should be increased gradually over a 30 – 60 second time frame.
  • Cross – flow velocity at set operating point should be achieved gradually over 15 – 20 seconds.
  • Permeate obtained from first hour of operation should be discarded.
  • Maximum pressure drop across an entire pressure vessel (housing) is 30 psi / 2.1 bar.
  • Avoid static permeate – side backpressure at all times.

Under certain conditions, the presence of free chlorine, chloramines and other oxidizing agents will cause premature membrane failure. Since oxidation damage is not covered under warranty, the manufacturer recommends removing all oxidizing agents by pretreatment prior to membrane exposure. Please contact the manufacturer or your supplier for more information.

Do not use this initial permeate for drinking water or food preparation. Keep elements moist at all times after initial wetting. To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution. Rinse out the preservative before use. For membrane warranty details, please contact the manufacturer or your supplier for more information.

If operating limits and guidelines given in this product specification sheet are not strictly followed, the warranty will be null and void. The customer is fully responsible for the effects of incompatible chemicals and lubricants on elements. Use of any such chemicals or lubricants will void the warranty. These membranes may be subject to drinking water application restrictions in some countries: please check the application status before use and sale. The use of this product in and of itself does not necessarily guarantee the removal of cysts and pathogens from water. Effective cyst and pathogen reduction is dependent on the complete system design and on the operation and maintenance of the system.

No freedom from infringement of any patent owned by the manufacturer or others is to be inferred. Because use conditions and applicable laws may differ from one location to another and may change with time, customer is responsible for determining whether products and the information in this document are appropriate for customer’s use and for ensuring that customer’s workplace and disposal practices are in compliance with applicable laws and other governmental enactments.
