An alternate form of Equation 11-14 is one based on the stoichiometric chemistry of ferric chloride assuming that the ferric chloride is purchased in solution and that there are no waters of hydration. Use Equation 3-10 to derive the coefficient for FeCl₃ assuming the ferric chloride dose in Equation 11-16 is mg/L as FeCl₃ instead of Fe; that is, find “x” in the following equation:

Equation 11-14.

M _s = 86.4 Q(0.44A + SS + M)

Equation 11-16.

M _s = 86.4 Q(2.9 Fe + SS + M)

Equation 3-10
