The treatment system includes a WAC, SAC, followed by a WBA and SBA. There is a degasser in this system. Calculate the amount of SBA resin required for the following data. M Alkalinity: 100 ppm as CaCO3 P Alkalinity: 100 ppm as CaCO3 Silica: 30 ppm as CaCO3 CO2: 45 ppm as CaCO3 EMA: 100 ppm as CaCO3 Capacity: 37 Kg/m3 Correction factor: 0.9 Flow rate: 35 m3/hr Operation hours: 10 hrs

SBA removes Silica, carbon dioxide and Alkalinity. The load for SBA which have adegasser prior to it, is considered as CO2 (5 ppm –residual Carbon dioxide) as CaCO3 + Silica as CaCO3 + 5% EMA. Ionic load= Anion as CaCO3 x Flow rate x Operating hours/1000. Resin Volume = Anion load / (Exchange capacity x Correction factor). Resin Volume = /(37 x 0.9)= 0.5 m3.
