A method for determining the size of anaerobic digesters

Abstract

With increasing interest in utilising wastes the number of people considering anaerobic digestion of wet wastes for biogas production is growing. To assist in sizing the digester and estimating gas production the simple steady state model of anaerobic digestion has been developed into a spreadsheet model. As many places where digesters are being adopted are in developing countries where computer access may be limited a design system based on tables has been set up so a computer is not required.
