Disposal of dairy whey by two stage biological treatment—I kinetic studies of the aerobic stage

A two stage biological treatment process has been proposed for the treatment of whey discharged from cheese and casein factories. The system consists of high rate anaerobic digestion followed by stabilization of the waste in a conventional activated sludge unit. This work embodies the determination of the kinetic parameters describing the second stage—the aerobic biological process. The relationships chosen to describe the system are based on the Monod empirical model describing biological oxidation processes.
