Find out the lime and soda in mg/L as CaCO3 to soften the subsequent water to a final hardness of less than 90 mg/L as CaCO3. Suppose the price of lime, purchased as CaO is $61.70 per megagram and the price of soda ash, purchased as Na2CO3 is $172.50per Mg. Define what is the annual chemical cost of treaing 0.050 m3/s of this water? Suppose the lime is 90% pure and the soda ash is 97% pure. The ion concentrations reported below are all mg/L as CaCO3

Ca = 137
Mg = 60
HCO3 = 197
CO2 = 9
