1. Biofilter modeling

In a biofilter, biomass and water are considered to be immobile in the reactor. Water is fed into the reactor to moisten the packing, meet the needs of the bacteria, and compensate for any evaporation caused by the unsaturated air flow . Among bioprocesses, biofilters are the most widely used, and models referring to them have been the subject of the most research to date. One of the oldest conventional models will be described below, which, due to its simplicity and simplifying assumptions, remains one...
