FEED WATER PARAMETERS:

  • Temperature: 85° F maximum
  • Pressure: 40 – 80 psi maximum
  • TDS: 2000-5000 ppm maximum (Consult Dealer for specific model)
  • Iron tolerance: 0.5 ppm maximum
  • Hydrogen sulfide: must be removed
  • Silica tolerance: can not be higher than 100 ppm in the concentrate stream.
    (Antiscalant should be considered for any levels over 75 ppm)
  • Turbidity: should be removed
  • Hardness: must be removed


OPERATING PARAMETERS:

  • Operating pressure: 150 – 200 psi maximum
  • Water recovery: up to 70% and is field adjusted by customer.
    (It is not recommended that the recovery be set higher than 70%)
  • pH range: 3 – 11
  • Flow rates are determined by the membrane mfg.’s. testing criteria of 1500 ppm Nacl solution, 77°F water temperature, 225 psi at 10-15% recovery. Typical membrane salt rejection is 95-99%

*Actual flow rates may vary depending on the pre-treatment used, water conditions, feed water temperature and applied pressure, etc.
