The co-production of hydrogen and methane from dark fermentation of mixed palm oil mill effluent and aquaculture wastewater : Gompertz modelling and sludge recovery
The potentials for non-stop hydrogen and methane production employing an ideal loading mixture of palm oil mill effluent (POME) and aquaculture wastewater (AWW) in a double-phase digester at a thermophilic state are presented. Different organic loadings were studied such as 31, 41, 51 and 61 Kg COD/...
