P$2-3(10$ pts$)$ The following data were collected from a coagulation jar test. The

Parraw water alkalinity was

$72m\frac{g}{L}$ as $CaC{O}_3.$

a$.$ Plot turbidity versus coagulant dose $($plot with straight lines between points$).$

b$.$ Determine the dose required for maximum turbidity removal for each coagulant.

c$.$ Determine the dose required for Stage $1$TOC removal for each coagulant.

d$.$ If alum costs $$0\mathrm{.}15$ per $lb,$ and ferric chloride costs $$0\mathrm{.}20$ per $lb,$ which will be most

economical for this water based on the overall removal needed?

e$.$ Explain the turbidity on with Ferric at $80m\frac{g}{L}.$ What would you do about it$?$
