Biodigestion

The preparation of the substrate consists in obtaining the physical-chemical characteristics considered optimal for introduction into the biodigester.

This occurs through the introduction of the matrices, possibly diluted by sludge and / or water, with a correct degree of humidity inside the Empowering Device which will homogenise all the matrices entered and pre-treat the result obtained, also contributing to the increase of the its temperature.

The permanence time of the matrix inside the biodigestor, normally 14/40 days (mesophilic reactors) or 14/26 days (thermophilic reactors), thanks to the pretreatment in the Empowering Device this permanence can be reduced to about one day and therefore reactors can be of extremely smaller dimensions than in the past can be made.

These are fed and, alternatively, emptied in cycles of 6 hours. They are equipped with biogas collection systems. During the pemanence, the material is continuously stirred through an innovative helical device that is moved only by exploiting the rise of the gas from the bottom to the top, without consuming additional electricity.

This allows to avoid the presence of dead zones, to homogenize the temperature and the release of the biogas and to avoid the sedimentation of the mud and the formation of superficial films and above all it facilitates the contact between bacteria and substrate.

The biogas obtained can be either upgraded to biomethane or, once purified, used for the low yield production of thermal or electric energy. It is a gaseous mixture composed mainly of methane and carbon dioxide, but also containing small quantities of hydrogen and occasionally traces of hydrogen sulphide.

The material exiting the biodigester is a liquid sludge (Solid Fraction: 5-25%) not completely stabilized (the organic matter is not completely degraded). It is stabilized through a second passage in the Empowering Device, which remove its bacterial load and accelerates its oxidation; subsequently, excess moisture is drained by means of a belt press.

Any excess nitrogen can be eliminated chemically, via bacteria or naturally with the compost rest. The liquid fraction thus obtained, having already undergone treatment within the Empowering Device, can be used immediately for irrigation purposes or to be returned to the cycle by finding new use in the biodigestor.

The dry fraction is used as a biological fertilizer (high quality compost).

The electricity produced by anaerobic digestion is considered totally green energy because the gas is not released directly into the atmosphere and carbon dioxide derives from an organic source characterized by a short carbon cycle, the biogas with its combustion does not contribute to the increase of atmospheric CO2 concentrations and, therefore, is considered a low environmental impact energy source.

  • Biodigestion
    • Anaerobic digestion

      It is a "cold" treatment, therefore it does not require any kind of combustion and cause few "natural" gaseous emissions which are completely absorbed in the biogas uptake and so in the subsequent filtering process of methane.

    • Biomethane Upgrade

      The biogas Upgrading Unit through amines, designed by us, is located downstream of the membrane unit and is suitable for implementation also on farms as it has a low level of danger, with a practically zero environmental impact, as well as being easily manageable by unskilled operators.

    • How its works

      Our biodigestion plant with methane upgrade involves the following processing steps: The material is added with a fluid matrix (water, other liquid waste, etc.) and sent to the Empowering Device, the biomass model, where all the matrices are homogenized, pretreated and sterilized. The materials are so introduced into the biodigester where them will be continuously remixed using only the inside...

    • BIOZIMMI

      We are talking about an atypical industrial plant which, instead of polluting, will proceed to remove pollution and improve people’s lives.

    • Empowering Device

      Empowering Device has been fully conceived, developed and implemented by our team and is able to simultaneously manage different types of controlled cavitation, of which 5 of a different nature but which coexist harmoniously to the point that no significant vibrations are detected.

    • Gasification

      In nature there is no "waste", everything is recovered and put back into circulation in a virtuous cycle.

    • Mining

      The current evolution of mining passes thorough the abandonment of methods that are dangerous for man and the environment, such as the use of mercury and cyanides, to get to Borax, a modern and harmless method, which also allows a better yield in recovered gold.

    • Plasma

      For Plasma refers to a conductive gas, highly ionized. The torch or the non-transferred arc electrodes are capable of producing plasma at very high temperatures (the highest achieved in controlled industrial processes) and such as to cause thermochemical dissociation of what is being treated.

    • Soil washing

      Most of our specialists and technicians come from the Oil & Gas sector and, therefore, has been taught to everyone of them, since the early beginning, that any spillage in the soil must be avoided. This is not only for obvious environmental problems but also to avoid costly and annoying protests by environmental movements.
