Rancangan Desain Pemilihan Reaktor Biogas

Biogas technology has been introduced and developed for long time in Indonesia, however application asalternative energy did not spread widely. There were several constrains such as lack of technical expertise,misfunction of the reactor, design is not user friendly, need manually handling and highly investment forconstruction. In the planning of biogas reactors have to consider several aspects, namely the number of cattle,Quality from cattle dung, biogas production locations and costs are available. Also consider the number ofbiogas users.Production of methane gas dependeds on C/N ratio of input material, hydraulic residence time, pH,temperature and toxicity. Temperature of slurry inside digester was around 25–27oC and pH 7–7.8, reactorproduced biogas that contain methane gas content about 77%
