Removal involves the processes of sedimentation and filtration. Inactivation means that even though the pathogenic organism might physically exist in the finished water supply, it has been rendered dead, inactive, or incapable of reproduction. Equation 2-1 is the fundamental equation for determining the number of organisms that are still viable after exposure to any disinfectant, including ozone. Equation 2-1 can also ‘be expressed as a natural-log (Ln) base-e value instead of a log base-10 value.
Calculate the log inactivation for every chamber, Log (No/N). 5. Calculate the total log inactivation for the entire reaction zone as the sum of log inactivation for every chamber, Log (No/N). It might seem logical to use a measured value at the entrance to the reaction zone as the initial ozone residual, but this practice is not recommended. , 1998). , within 1 min of reaction time), which is followed by a somewhat slower first-order decay profile. , chambers 5 and 7 in the example). The average ozone decay rate, k*, is determined from the decay rate equation (Eq.
Calculate the ozone decay coefficient, k*. 2. Calculate the residual at the entrance of the reaction zone, Co. 3. Calculate the characteristic residual for every reaction chamber, Char. 4. Calculate the log inactivation for every chamber, Log (No/N). 5. Calculate the total log inactivation for the entire reaction zone as the sum of log inactivation for every chamber, Log (No/N). It might seem logical to use a measured value at the entrance to the reaction zone as the initial ozone residual, but this practice is not recommended.
