Anaerobic Function

Optimum pH for hydrolyse and acidification stage < 7(distillery waste between 4,0 and 6,0)

Optimum pH for hydrolyse and acidification stage < 7(distillery waste between 4,0 and 6,0)

Optimum pH for development of methane bacteria > 7 (7,2 till 7,8)

Optimum pH for development of methane bacteria > 7 (7,2 till 7,8)

In the hydrolyse phasehydrolyse phase, the organic molecular links have to be released through enzymes and be transformed into water soluble elements.

This process still happens in aerobic environment

In the acidification phaseacidification phase, the bacteria (facultative and compulsory anaerobic) develop short chain organic acids, alcohols, H2 and CO2.

Also ammoniac and H2S are released.

In the acetogeneacetogene phasephase, the short chain organic acids, alcohols,are disintegrated into acetic acid.

In the methanogenemethanogene phasephase, methane will be finally formed out of mainly acetic acid and also out of H2

and CO2.

Possible design arrangement

From < 100 m3 until over 2 500 m3

mainly in steel reinforced concrete, may also be in steel as stand up tank From < 100 m3 until over 2 500 m3

Benefit of the system

Simple design, economic and request low maintenance cost

High gas production

High gas quality

Odours emission is kept at a very low level (released substrate is smell neutral)

No floating layer

Sediment if any can be removed from hydrolyse stage very easy without stipping the production

Controllable substrate regular flow without immersed pumps or agitators

Due to the regularity, the fermentation process can be continue controlled through samples tests

Very compact, doesn’t required large area
