Calculate the amount of resin required for the following information. Cation Load: 100 ppm as CaCO3 Capacity: 57 Kg/m3 Correction factor: 0.9 Flow rate: 135 m3/hr Operation hours: 20 hrs

Correct Answer: 5.3 m3
Cation load= Cation as CaCO3 x Flow rate x Operating hours/1000. Resin Volume= Cation load/ (Exchange capacity x Correction factor). Resin Volume =/(57 x 0.9)= 5.3 m3.
