On the determination of the kinetic parameters for the BOD test

One of the most common tests for the determination of the organic content of wastewater is the biochemical oxygen demand (BOD). The kinetic parameters k (rate constant) and L (ultimate demand) can be estimated by different methods, such as: non-linear fitting, linear fitting of modified expressions...

Description
Summary:One of the most common tests for the determination of the organic content of wastewater is the biochemical oxygen demand (BOD). The kinetic parameters k (rate constant) and L (ultimate demand) can be estimated by different methods, such as: non-linear fitting, linear fitting of modified expressions of the BOD equation, and the Thomas method among others. In this note, three of the most common methods for the determination of k and L are compared. Particular attention is paid to the accuracy of each method.
