Parkin and Owen (1986) report the following parameter values for anaerobic digestion of primary treatment sludge: Ks=half-saturationconstant=1.8(1.112(T35))[mgCOD/L];max=maximumspecificgrowthrate=0.27(1.035(T35))[day1];k=maximumspecificsubstrateuserate=6.67(1.035(T35))[day1];kd=endogenousrespirationrate=0.03(1.035(T35))[day1];T=temperature[C]VCH4=[Q(SoS)1.42Px,vsS][LCH/d]=Methaneproductionconversionfactor=0.0013(273+T)[LCH4/gCOD]Additionalinformation:Xo,i=0.15mg/L,Volumeofdigester=100m3,fd=0.15mg/mg,waste-utilizationefficiency()=85%,S=13.5mgCOD/L The digester is loaded at a rate of 550kgCOD/d and the reactor operates at 30C. From the information given as well as equations provided in the back of the paper determine: a) The influent COD concentration to the digester. b) The volumetric flow of water (Q) through the digester. c) The methane production rate (m3/d) at the prevailing conditions in the digester. d) Total gas (VTot) and CO2(VCO2) production rates (m3/d) if it is known that the composition of biogass is 64% methane, and 3%H2S content in the biogas. YOU MAY ASSUME THAT ONLY CH4,CO2 AND H2S ARE PRESENT IN THE BIOGAS
