Question

: Determine the lime and soda ash dose, in mg/L as CaO and Na₂CO₃, to soften the following water to a final hardness of 80.00 mg/L as CaCO₃. The ion concentrations reported below are all as CaCO₃. Assume lime is 94 percent pure and soda ash is 93 percent pure.

Ca²⁺ = 155.0; Mg²⁺ = 62.0; HCO₃^- = 136.0; CO₂ = 12.0

Expert Solution

Step 1

Given ,

Final hardness $= 80.00 \frac{m g}{m L}$

Purity of lime = 94 %

Purity of soda ash = 93 %
