A complete-mix anaerobic digester is used for processing food waste at a mass flow rate of 1000kg/d an volume flow rate of 1.0m3/d. The hydraulic retention time is 25d. Determine the following: a) Size of the digester (m3) b) Organic loading rate (kgVS/m3d) c) Maximum possible biogas production rate ( m3 biogas/d), based on the potential biogas yield d) Actual biogas production rate (m3 biogas/d) e) Actual methane production rate (kgCH4/d) f) Electricity production via cogeneration (kW) based on the actual methane production rate sugstrate: voratie sonus ( vo) or iove waste Note: Equations for calculating electricity production: Ep=EceEc=FHc where Ep: electricity production, kW Ec: energy produced through combustion, MJ/d F: actual methane production rate, kgCHCH4/d H: heat of combustion (methane), MJ/kg c: combustion efficiency, % e : electrical energy conversion efficiency, \%
