FilmTec™ XLE PRO-2540 Tape-Wrapped Low Energy Large Commercial Elements for Commercial Applications

Tiparet kryesore

  • High flux results in high yields
  • Produce good water quality at very low applied pressure for drinking water and commercial applications

Specifikat

Key Applications

Drinking & Commercial water applications for plant sizes ≤ 500L/hr (0.5M3/hr) – Hotels, Restaurants, Cafes, Car wash, schools, refiling stations, etc

Typical properties

  • Nominal active surface – 2.6 m²
  • Permeate volume – 3.8 m³/day
  • Stabilized salt rejection – 99.0 %
  1. Permeate flow and salt rejection based on the following test conditions: 77°F (25°C), 15% recovery, applied pressure 125 psig (8.7 bar), pH 8, and based on a 2,000ppm NaCl feed stream.
  2. Minimum salt rejection is 97.0%.
  3. For the purpose of improvement, specifications may be updated periodically.

Operating and Cleaning Limits

  • Maximum operating water temperature – 45 °С
  • Maximum operating pressure – 41 °С
  • pH range, operational mode – 2…11
  • pH range, chemical cleaning mode – 1…13
  • Maximum feed silt density index SDI < 5
  • Free chlorine tolerance – <0.1 ppm

General information

  • Keep elements moist at all times after initial wetting.
  • If operating limits and guidelines given in this bulletin are not strictly followed, the limited warranty will be null and void.
  • To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements beimmersed in a preservative solution.
  • The customer is fully responsible for the effects of incompatible chemicals and lubricants on elements.
  • Maximum pressure drop across an entire pressure vessel (housing) is 30 psi (2.1 bar).
  • Avoid static permeate-side backpressure at all times.
  • Avoid any abrupt pressure or cross-flow variations on thespiral 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 stateis recommended as follows:
    – Feed pressure should be increased gradually over a 30-60second time frame.
    – Cross-flow velocity at set operating point should be achieved gradually over 15-20 seconds.
  • 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.
  • Permeate obtained from the first hour of operation should be discarded.

Important information

  • 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. Following the proper start-up sequence also helps ensure that system operating parameters conform to design specifications so that system water quality and productivity goals can be achieved.
  • Before initiating system start-up procedures, membrane pretreatment, loading of the membrane elements, instrument calibration and other system checks should be completed.
  • Please refer to the application information literature entitled Start-Up Sequence (Form No. 45-D01609-en) for more information.
