Domestic Biogas Plant Construction Complete Guide 3rd Part
Domestic Biogas Plant Construction Complete Guide
In first part of Gobargas domestic biogas plant construction manual, we discussed it’s contents,
in detail, biogas introduction and development around the world. In 2nd part material required for a home biogas plant, benefits of gobar gas domestic biogas plant, its models, and components were discussed. In this part I will try to
describe its fixing, installation, this is a very important
step, it requires so much care and attention. I divide it into further parts so
that the reader can understand it easily.

Size Selection of Biogas Plant Design
Size selection is the first important step for gobar gas/biogas plant construction. The size of a biogas
plant depends on the daily available quantity of feeding materials/gobar and biogas
requirements. In size selecting preference should be given to the availability of
dung, not the family size or gas demand.
On the basis of size,
fixed biogas plant design is divided into the following four types.
Size of fixed biogas the plant design can be classified on the basis of the quantity of fuelwood saved per
day and the availability of feeding material cattle dung etc.
Construction Site Selection
Construction site
selection is also an important step, the following factors must be kept in mind
during site selection.
- The site should be easy for construction works and guarantee plant safety
- There should be a site of minimum 10*15 feet for a family size biogas plant
- It should be away from the shade of tree or wall.
- It should be away from the water reservoir, and the water table should be a minimum of 15 feet.
- The temperature inside the digester should be 20-35°C, so avoid the damp and cool place, Sunny site is preferable.
- The kitchen should be near as possible.
Quality Standards 0f Construction Materials
Quality standards 0f
construction materials is of supreme importance for the proper functioning of the biodigester.
Thè materials required mainly are cement, sand, gravels, bricks, acrylic
emulsion paint, mild steel bars, main gas pipe, main gas valve, gas stove, gas
pressure gauge and mixing device.
