Abstract

Absract This work determined the dependency of biogas and carbon (iv) oxide production on microbial concentration X (Cfu/l), hydraulic retention time (HRT), ratio of total volatile fatty acid (TVFA) and total alkalinity K, during anaerobic decomposition of brewery effluent wastewater in a fluidized-bed reactor system. The volume of biogas and carbon (iv) oxide produced were monitored as the treatment time progressed. For brewery waste water volume of 2 litres treated in the bioreactor, the volume of biogas rich in methane, produced in this work was described as s-curve with initial volume of biogas produced as 0.003l at 4h HRT and maximum volume of 0.0045l at 8 h HRT.Similarly,0.0033l of carbon(iv)oxide was recorded at 2 h HRT and it achieved its maximum of 0.0042l at 8 h HRT. Total microbial count was conducted on the reactor sample water. The maximum concentration of the gases recorded at 8 h HRT corresponded to the favourable operating environment and good system stability ratio (VFA/Alkalinity)<0.5 achieved.
