Disinfection Design

Example

Given the following chlorination test survival data for E$.$ coli, expressed as percentage, determine the values of the constant in the Chick and Watson equation for $99\%$ reduction. The resulted obtained from a batch reactor are

$\backslash$table$[[$Free $C{l}_2,m\frac{g}{L},$Percent survival$],[$Contact time $($min$)],[1,3,5,10,20],[0\mathrm{.}05,97,82,63,21,0\mathrm{.}3],[0\mathrm{.}07,93,60,28,05,-],[0\mathrm{.}14,67,11,0\mathrm{.}7,-,-]]$

Test condition $pH=8\mathrm{.}5,$ temperature $=5C$
