Preliminary Investigation on Production of Biogas from Domestic Sewage

A review of biogas production methods from wastes and sewage and the explanation of its process

Thousands of tons of urban solid waste and human and animal waste in cities and villages of Iran have endangered the health of the environment and increased the greenhouse gases. On the other hand, the increasing trend of energy consumption has caused energy crisis phenomena in the world. Moreover, the increasing consumption of energy from fossil fuels has caused emissions from these fuels. Hen...

estimation of production potential of biogas and electricity from municipal sewage sludge in the iran

producing biogas is the most common method of energy generation in municipal and industrial wastewater treatment plants in the world. methane production rate depends on degradation rate of organic pollutants in wastewater, temperature and treatment process. typical parameters for assessment of organic wastewater such as bod or cod indicate the potential to produce methane. there is no accurate ...

Biogas Production from Fish Wastes in Co-digestion with Sewage Sludge

Fish wastes have great potential as a source of high valued organic carbon for methane production but also have limitation (high content of ammonia nitrogen). Anaerobic treatment of fish wastes is possible with co-digestion. The main issue for co-digestion process lies in balancing several parameters in the co-substrate mixture: macroand micronutrients, C:N ratio, pH, toxic compounds, biodegrad...

Production of Biogas from Poultry Waste

It is inevitable that with large volume and high density poultry productions, there will be large quantities of poultry waste produced in Kathmandu and throughout Nepal. Poultry waste produced as the daily feeding of chicken both from broilers and layers in the country is largely used as organic manure for agricultural purposes. The poultry industry is growing day by day concentrated within the...
