Subject: Biogas in Mbarara (Uganda)

Two large tanks were bought (one slightly smaller).

The tanks were marked with Chalk prior to cutting

Note: The digester being constructed here is

a “Floating Drum” type digester and is“semi continuous” in that it will be fed

plantain peelings and other waste on a daily

basis. Some inoculum may be needed tointroduce the right microbes to generate

methane.

It is estimated that a unit such as this would

take 2 people 4-6 hours to construct.

One of the tanks' (the digester) was cut out to match the smaller gas holder tank.


3/10

The Gas holder is made by removing the entire top

A hot metal pipe is used to make the inlet and outlet holes (on opposite sides)

Inlet (left, also acts as drain for emptying digester) and outlet (right) pipes are pre assembled

Outlet pipe is fitted

Fitting the inlet pipe

Outlet pipe is finished


6/10

The Digester is ready (from inlet side)

Time to rest inside the digester (from top, showing inlet pipe)


7/10

Bricks used to support the gas holder as it falls back (replaced by sand filled bottles below).

Plastic bottles were used to support the inlet pipe, instead of clay burnt bricks!

Filling the bottles

Gas holder goes onto the digester

Dr GW loved the job (here you ca see the inlet (right) and outlet (left). Gasholder not visible

prior to filling.

Sketch of supports for Inlet and Outlet pipes, held by a strap (use your imagination here!).

Detail of the gas outlet, on the gas holder.

Time to have a photo! It was a great job. I will test the gas after 14 days

Share with a friend,

Cheers
