Biogas production from wastewater and organic waste
The technique consists of a fixed-dome plant consisting of a digester with a fix non-movable gas holder located in the top of the digester. When gas production starts, the slurry is displaced into the compensation tank. Gas pressure increases with the volume of gas stored and the height difference between the slurry level in the digester and the slurry level in the compensation tank. The anaerobic digestion process is a green technology involving the generation of methan rich bio gas via the biological degradation biomass from the organic waste.
The biogas is then obtained from the fermentation of organic waste soluble in wastewater with low levels of suspended solids.
Biogas production units provide a renewable energy source for households for cooking, reducing the use of fossil fuels emitting carbon dioxide. One such unit alone produces the equivalent of five gas pot pipes each month from the fermentation of organic waste. Around 8 –10 m³ biogas plant produces 1.5-2 m³ gas and 100 litres of digested slurry per day using dung from 3-5 cattle. The new biogas production units are also used to produce organic fertilizer that improves the properties of the soil. Bioenergy improves the quality of life through economic and sustainable energy sources with improved hygiene and sanitation conditions for Sustainable Development.
