Fig. 11.2 Survivor/time curves
for the disinfection process.
A, obtained if the disinfection
process obeyed the first-order
kinetic law. B, sigmoid curve.
This shows a slow initial rate of
kill, a steady rate and finally a
slower rate of kill. This is the
form of curve most usually
encountered. C, obtained if
bacteria are dying more quickly
than first-order kinetics would
predict. The 'constant', K,
diminishes in value continuously
during the process.
