2.5″ x 40″ RO Membrane Elements 100 PSI

AXEON HF4 – Series Reverse Osmosis Membrane Elements operate at extra - low energy pressures of only 100 psi, while producing a nominal salt rejection rate of 99% and reaching flow rates up to 2,500 gallons per day. Protected with a hard ABS shell for improved structural integrity, RO Membrane Elements 100 psi are the upgraded choice for extra - low energy savings and for reducing costs and applying less stress on RO system fittings and components.

Warranty Evaluation Test Conditions: Permeate flow and salt rejection based on the following test conditions – 550 ppm, filtered and dechlorinated municipal tap water, 77°F / 25°C, 15% recovery and the specified operating pressure. Minimum salt rejection is 96%. Permeate flows for warranty evaluation may vary +/-20%. Maximum pressure drop at 13 psig / 0.9 bar.

All 2514, 2521 and 2540 elements fit nominal 2.50” I.D. membrane housings and all 4014, 4021 and 4040 elements fit nominal 4.00” I.D. membrane housings.
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.
