الملخص EN
A government-sponsored initiative in Indonesia to design and implement low-cost anaerobic digestion systems resulted in 21 full-scale systems with the aim to satisfy the cooking fuel demands of rural households owning at least one cow.
The full-scale design consisted of a 0.3 m diameter PVC pipe, which was operated as a conventional plug-flow system.
The system generated enough methane to power a cooking stove for ∼1 h.
However, eventual clogging from solids accumulation inside the bioreactor proved to be a major drawback.
Here, we improved the digester configuration to remedy clogging while maintaining system performance.
Controlled experiments were performed using four 9-L laboratory-scale digesters operated at a temperature of 27 ± 1 °C, a volatile solids loading rate of 2.0 g VS·L−1·day−1, and a 21-day hydraulic retention time.
Two of the digesters were replicates of the original design (control digesters), while the other two digesters included internal mixing or effluent recycle (experimental digesters).
The performance of each digester was compared based on methane yields, VS removal efficiencies, and steady-state solids concentrations during an operating period of 311 days.
Statistical analyses revealed that internal mixing and effluent recycling resulted in reduced solids accumulation compared to the controls without diminishing methane yields or solids removal efficiencies.
