Our equipment finds an optimal location both at the entrance of the biodigestor, after preliminary laboratory characterization on digestate samples taken in order to quantify the specific advantages in the specific case, and at the output to reduce the charge of microorganisms present or, even, in recirculation.
The main benefits are related to the reduction of the size of the organic material, the reduction of the viscosity of the digestate and the consequent ease of mixing inside the digester, in addition to the increase in the homogeneity of the digestate and, therefore, to the better pumpability which result in a overall improvement of the fermentation process.
It should be specified that as the rotation frequency changes, more or less energy can be imparted to the biomass to be treated and therefore greater or lesser treatment efficiency.
- Increases the efficiency of the fermentation processes
- Drastically reduces the production time of biogas
- It reduces the consumption of substrates for the same biogas produced
- Increases the production of biogas with the same amount of fed substrates
- Increases the methane content in the biogas
- Reduces the viscosity of the digestate by facilitating pumping and mixing
- It reduces the energy consumption of the mixing and pumping organs
Furthermore, thanks to the fact that cavitation acts directly on the fibrous component of the matrices, increasing their methanigenous potential, various agro-industrial by-products (straw, pomace, exhausted marc, etc.) can be used which previously could not be adequately valued for energy purposes, thus further reducing the operating costs of the biogas production plant.
Tests conducted on first generation cavitators, capable of a single controlled cavitation, have shown that the peak of methane production is obtained in just 2.5 days from cavitation against the over 25 needed previously in traditional systems. The experimentation conducted on our apparatus further reduced these times to just a few minutes.
