The disinfection kinetics are conventionally calculated via the Chick-Watson model, named for the work of Harriette Chick and H. E. Watson. This model is expressed by the following equation: $${\displaystyle \ln({\frac {N}{N_{0}}})=\Lambda _{CW}C^{n}t\!}$$ Where: $${\displaystyle ({\frac {N}{N_{0}}})\!}$$ is … See more CT Values are an important part of calculating disinfectant dosage for the chlorination of drinking water.
