Performance study for anaerobic digestion of municipal solid waste in a single phase reactor
Anaerobic Digestion (AD) has been up to now essentially applied to wastewater. However, anaerobic treatment of organic solid waste fits well with the new requirements for waste management. A batch study of vegetable market waste composed at various solid concentrations was studied in a single phase anaerobic reactor. Prior to this, studies were also carried out in aspirator bottles of different capacity to select essential factors influencing the Single Stage High Solid (SSHS) approach with emphasis on C/N ratio. Initially, the maximum total solid concentration was optimised, which gives maximum biogas yield and at maximum total solid concentration, further experiments were carried out with varying C/N ratio to arrive at optimum C/N ratio leading to maximum biogas yield. This paper describes the performance of AD of municipal solid waste in a laboratory-scale reactor for varying solid concentration and C/N ratio.
