Methane Generation via Two-Phase Anaerobic Digestion of Organic Fraction of Municipal Solid Wastes

Article Preview

Abstract:

The performance of a small-scale two-phase anaerobic digestion system which processes municipal solid wastes, i.e. vegetable and fruit wastes, was evaluated at mesophilic conditions. An anaerobic digester which required 5 L of fresh cow manure, 5 L of solid waste feed, 5 L each of leachate from the solid waste, and 1 L of anaerobic seeding had been constructed. The volume of the feed solids after digestion has significantly reduced after the operation. The total accumulated methane for a solids retention time (SRT) of 20 days contained useful heat energy amounting to 330.27 KJ.
