ABSTRACT
Hydrogen (H2) is a sustainable and variable form of green and alternative energy sources. H2 is one of the most promising alternative fuel sources for satisfying future energy demands. Current research on H2 production is being conducted on carbohydrate-rich wastewater which has the ability to produce renewable energy outputs like hydrogen. Dairy wastewater is one such carbohydrate-rich high-volume industrial wastewater which is suitable for H2 production. The biohydrogen production using dairy wastewater influencing factors such as initial pH of the influent, temperature, and hydraulic retention time (HRT) were investigated in this paper. Optimized operational conditions for biohydrogen production were found to be 6.5 pH, 55°C temperature and 6 h HRT.
