Abstract
There are a number of ways in which digestion can be carried out even with one type of feedstock, and considering various types of feedstock the number of ways can be multiplied. The question of which method to use may be answered in principle by consideration of what is known of the methods of laboratory or industrial fermentation, but the successful application of these methods is generally a matter of trial and testing of small- and then larger-scale plants. Complete design of a plant depends on knowledge of all factors involved, and in many digester situations these are not known. Nevertheless, theory and modelling can have some place in digester design. The theories of bacterial growth and running of batch and continuous cultures may give some help in considering which of two systems to adopt or what basic design features are needed. These theories lead to what one might call ‘biological models’.
