Suggested Operating Capacity

The operating capacity of the mixed bed can be estimated using the following formula, which gives an approximate determination of volume of water that can be treated:
 23000        
conductivity (μs/cm)

Note: Where BV* (Bed Volume) is the number of liters of a feed water containing a conductivity given in μs/cm that can be demineralized with one liter of the resin mixture when run to treated water conductivity 0.1μs/cm.
This data is tested under below condition:
A. feed water containing a conductivity as 100μs/cm
B. service flow rate as 60BV/h
