REACTOR START-UP STRATEGY AS KEY FOR HIGH AND STABLE HYDROGEN PRODUCTION FROM CHEESE WHEY THERMOPHILIC ANAEROBIC DIGESTION

Using the right start-up strategy can be vital for successful hydrogen production processes from thermophilic anaerobic digestion, but it also needs to be economically feasible. Hence, three start-up strategies modifying only influent concentration and temperature were assessed in a thermophilic sequencing bath reactor fed with cheese whey.
