Biométhanization
The biomethanization or anaerobic digestion consists of the disintegration – due to the absence of oxygen – of various organic substances which leads, amongst other things, to the production of methane (CH4): the latter is valorised in the form of heat and/or electricity.
This biochemical disintegration is carried out by several consortiums of bacteria, each of them operating at a distinctive stage within the global process. The first stage is the hydrolysis, which is operated by the extra-cellular enzymes that are produced by bacteria. This stage is characterized by a cutting up of the macro-molecules into smaller components, making them easier digestible for the other bacteria populations.
REALCO has been able to demonstrate that this stage of production of enzymes is the limiting stage of the entire process of transformation of the organic material.
The adding of extra enzymes, which on top of that are specifically adapted to the substrate, allows us to considerably accelerate the kinetics of the entire chain of reactions. The implementation of an enzymatic hydrolysis into your anaerobic digester or autoclave offer a multitude of benefits:
- Reduced length of stay and/or an increase of the volume accepted by the digester.
- Improvement of the DCOin/DCOout output: interesting in case your autoclave or digester is saturated.
- Increase of the biogas production (15 to 35%, depending on the substrate)
- Liquefaction (DCOs increase) of certain substrates that might plug up, which allows you to avoid any problems of stoppage or blockage.
The BIOMETHAZYM range has already proved to be effective on several substrates: manure, stable dung, energetic plants, wastewater treatment silt or sediment, greasy residue, vegetable pulp…
Our team of technical commercial staff members is at your disposal for any proposition with respect to this type of treatment: please feel free to call us and, together, we can proceed to an on-site assessment of the feasibility of such an enzymatic hydrolysis.
