1.     Allowable continuous flow is flow at 15 psi max head loss or 10 gpm/ft³ which ever is less.  

2.     Allowable peak flow is flow at 25 psi max head loss or 15 gpm/ft³ which ever is less.

3.     Backwash Flow Rate is 5 gpm/ft², which provides 50 to 75% resin bed expansion.

4.     Brining efficiency at 0.26 Kgr/lb of salt applied.  Assumes 90% utilization of capacity.

5.     Brining efficiency at 0.47 Kgr/lb of salt applied.  Assumes 90% utilization of capacity.

6.     Six-inch diaphragm valves require Humphrey pilot valves.
