|Average Permeate Flow
• Specifications are based on a 2000 mg/L NaCl solution at 420 psig operating pressure (2930kPa), 77deg.F,(25deg.C), 10% recovery, pH 6-7. Individual flux may vary +15%/ -15%. Average salt rejection after a minimum of 24 hours in continuous operation.

• The Langelier Saturation Index (LSI) of the concentrate must be negative to minimize the posibility of calcium scale formation on the membrane surface. At start-up the first two hours of permeate should be discarded because of element preservative. Storage conditions should be less than: <100F, dry, in original carton and not in direct sunlight.
