CE $380$ Assignment $3,$ due $9/12/2024$ Thurs. at $9$pm to Blackboard

For each of these three water samples

$(1)$ calculate meq$/$L for each chemical component

$(2)$ draw bar chart $($see the class example$)$

$(3)$ using the bar chart to determine alkalinity, calcium carbonate hardness, magnesium carbonate

hardness, calcium noncarbonate hardness, magnesium noncarbonate hardness $($report in meq$/$L$)$

$(4)$ determine the required amount of $($a$)$ lime $($report in $I\frac{b}{d}$ as CaO,$95\%$ pure$).($b$)$ soda ash $($report in

$I\frac{b}{d}$ as $N{a}_{2}C{O}_3,95\%$ pure$)$ for treating $1$ MGD of the water by excess$-$lime water softening process.

The required excess lime is $35m\frac{g}{L}$ as CaO
