5. Industrial control of biochemical reactions in reactors
5.1 Plant start-up and shut-down
The availability of suitable biomass (granular or flocculated) considerably improves reactor start-up times and procedures. Mass seeding is the key to a successful start-up of an anaerobic digestion reactor.
Of all the technologies developed to date, those using granular sludge facilitate mass seeding (see § 3.4

Statistical and economic data
Given the difficulty of keeping up-to-date information on anaerobic references, you will find below economic data dating from 2002. Only industrial plants larger than 2 to 3 tons COD/day could be identified through published manufacturer data, or by taking into account plants known but not precisely referenced by the manufacturer, or in databases specific to each industry. However, these data show that the...
