†Calculated using a 0.85 fouling factor
*Nominal capacity based on new RO membranes operating on a properly pretreated feed water of 500 ppm TDS as NaCl,
77 °F (25 °C), Silt Density Index (SDI) below 3, and supplying water to atmosphere. Productivity will vary depending on
the actual feed water quality and temperature.
