How much soda ash (Na2CO3) in kg/day do you need to add to remove calcium hardness from 200 mg/L CaCO3 to 50 mg/L CaCO3 if you have a water source with flowrate of 1000 m3/day. Consider the following unbalanced reaction that describes the process of Ca2+ removal. Ca2+ + Na2CO3 ↔ CaCO3↓ + Na+ Considering the soda ash has 96% purity and it costs $0.5/kg, how much would it cost the water treatment plant per year (365 days)?
