Multiply the nominal product flow at 25° C by the temperature correction factor to

determine the flow at various other temperatures.

VI. Appendix

The following tables are intended as a guide to determining the flow

rates for the PWR4024 series RO systems. All flows are in gallons

per minute (GPM).
Nominal flows for systems with reject recycle and a feed water

Silt Density Index less than 3.

Nominal flows for systems with reject recycle and a feed water

Silt Density Index of 3 to less than 5.
