AGAMA BiogasPro3

AGAMA BiogasPro3

The AGAMA BiogasPro-3 is our latest digester, and was launched in 2012 for testing and to the market in 2013.  It is best suited small households in rural or new development applications, and in formal sewer environments where the application is below-ground with the inlet sewer depth of 330 mm.

The AGAMA BiogasPro3 does the following:

    • mixes the contents for increased gas generation efficiency
    • naturally decomposes biodegradable materials without the additional any chemicals
    • stores the biogas that is generated by this natural decomposition
    • generates an internal pressure which allows the biogas to be piped directly to the point of use
The digester mixing, gas storage and pressurisation are all achieved without any mechanical input at all i.e. no pumps or motors of any kind.
 
It weights 120 kg, has a total volume of 4500 litres, and can store up to 800 litres of biogas.
 
 
The AGAMA BiogasPro3 is shipped in 4 pieces to reduce the transport costs. Watch how to assemble the BiogasPro3 on Youtube here

    Environmental specifications
    Operating temperature: +10°C to +40°C
    COD reduction 50% - 98% ( feedstock and loading conditions dependent)
   
    Loading specifications
    • Feeding rates are feedstock and temperature dependent. A maximum of
500 litres of water can be added daily
    • Expect a difference in gas production between winter and summer
months. Loading should be reduced in winter to account for the slower
biological activity

    • The recommended minimum ratio of fresh feedstock to water is 1:2
   
    Energy specifications
    • Biogas production is proportional to the amount of feedstock and
operating temperature
    • Biogas contains approximately 60% methane (CH4), 39% carbon dioxide (CO2) and 1% hydrogen sulphide (H2S)
    • Each cubic metre of biogas has the heating capacity of
approximately 0.43 kg LPG
    • The nominal daily energy output is equivalent to approximately 0.5 kg LPG
