FIXED DOME BIODIGESTER


Advantages of fixed dome type of biogas plant

  • Requires only locally and easily available materials for construction.
  • Inexpensive.
  • Easy to construct.

FLOATING DRUM BIODIGESTER

This is illustratyed by the diagram below;

Advantages Floating drum biodigester:

  • simple, easily understood operation
  • The volume of stored gas is directly visible.
  • The gas pressure is constant, determined by the weight of the gas holder.
  • The construction is relatively easy, construction mistakes do not lead to major problems in operation and gas yield.

TUBULAR BIODIGESTER

This is illustrated by the picture below;

Advantages of a Tubular Biodigester;

  • Simple
  • Easy to construct
  • Inexpensive
  • Good in gas storage

PLASTIC BIODIGESTERS

This is illustrated by the diagram below;

The sketch below illustrates how the plastic tanks are linked up in a floating dome plastic biogas digester;

The advantages of a plastic biodigester are;

  • The plastic biodigester is simple and easy to construct from readily available materials and its operation does not require special skills.
  • Farmers can do the set up by themselves.
  • Biodigester technology enhances energy supply decentralization, for instance rural communities having difficulties or no access to commercial fuels can produce biogas to meet their fuel needs, thereby increasing reliability of fuel supply and enhancing energy security to the rural areas.
  • Plastic biodigesters can be used for treating the waste water in livestock units
  • Reducing the work of women in the household.
