The Impact and Treatment of Night Soil in Anaerobic Digester: A Review

Antony Daisy and S.Kamaraj

With the aim of improving knowledge about the stability and reliability of anaerobic night soil treatment systems, several researchers have studied the effects of different digester design and operational performance of such digester. In general, anaerobic digesters are affected by changes in external factors, but the severity of the effect is dependent upon the type, magnitude, duration and frequency of the imposed changes. Special attention is paid to the advantages of anaerobic digestion in limiting the emission of greenhouse gases This review summarises the causes, generation rate of night soil , composition of slurry, pathogen and its harmful effects and effects of operation in different digester on anaerobic night soil treatment systems. However, there still remain some unclear technical and scientific aspects that are necessary for the improvement of the stability and reliability of anaerobic processes. An overview of research achievements and future developments is given.
