Activated Sludge Model No. 3

The Activated Sludge Model No. 3 (ASM3) can predict oxygen consumption, slu dge production, nitrification and denitrification of activated sludge syste ms. It relates to the Activated Sludge Model No. 1 (ASM1) and corrects for some defects of ASM I. In addition to ASM1, ASM3 includes storage of organi c substrates as a new process. The lysis (decay) process is exchanged for a n endogenous respiration process. ASM3 is provided as a reference in a form which can be implemented in a computer code without further adjustments. T ypical kinetic and stoichiometric parameters are provided for 10 degrees C and 20 degrees C together with the composition of a typical primary effluen t in terms of the model components.
