Water treatment plant operating at 25,000 m'/day, needs to treat water with following characteristics; Calcium bicarbonate = 200 mg/L, Calcium sulfate = 100 mg/L, Carbon di oxide = 20 mg/L. Use caustic soda (NaOH) and soda ash (NazCO3). Calculate; Total Hardness (mg/L as CaCO3) ii Carbonate hardness (mg/L as CaCO3) Non-carbonate hardness (mg/L as CaCO3) Water softening chemicals needed (kg/day) Amount solids produced per day (kg/day)
