Calculate the amount of resin required for the following information. Cation Load: 30 ppm as CaCO3 Capacity: 47 Kg/m3 Correction factor: 0.9 Flow rate: 135 m3/hr Operation hours: 20 hrs

Correct Answer: 1.8 m3
Cation load= Cation as CaCO3 x Flow rate x Operating hours/1000. Resin Volume= Cation load/ (Exchange capacity x Correction factor). Resin Volume =/(47 x 0.9)= 1.8 m3.
