Digester

A digester is a Cuve which produces Biogaz thanks to a process of Méthanisation of the organic matters.

These tanks must be heated so that the Rendement is acceptable. They are digesters Mésophile S most of the time but there exist also engines Thermophile S. the advantages are multiple and in particular on the level of the odors and the bacteria which are destroyed. An engine produces surroundings 50 to 70% of Méthane, 30% of CO₂ and water, the sulphuretted Hydrogène (H₂S) and of the Oxygène. The advantages are numerous.

The principal sizes which characterize an anaerobic engine of digestion are:

the density of volume charge applied: it is about the quantity of DCO introduced into the engine per day and unit of volume of the engine. It makes it possible to compare the quantity of pollution treated by various types of engine.
the hydraulic residence time (TSH) corresponds to the duration of the contact between the effluent and the biomass. It represents the relationship between the volume of the engine and the rate of feed. The TSH makes it possible to know the volume of effluent which one can treat each day in the engine.
quantity and the composition of gas: the quantity of gas can be paid to the quantity of organic matter eliminated (output) or to volume from the engine (productivity). The composition of gas is variable depending on the state of the engine.
