Bio-fermentation processes under control:
Real–time monitoring in bioreactors
Composting with bioreactors considerably reduces treatment times, thanks to the forced aeration of the organic matrix and the control/regulation of physical quantities. Whether rotating cylinders, silos or biocells are used, in order to obtain a high quality, stable and mature compost the aerobic process must be managed correctly.
How? Through real-time monitoring of the main parameters, such as temperature and air oxygen which passes through the ducts.
However, continuous measurement can sometimes be complex; both as regards the mounting of sensors in confined spaces, and for the ordinary maintenance of the same.
This, in fact, is the main challenge underlying the collaboration with Secit Impianti (Gesenu Group) – a company specialised in the design, construction and management of waste treatment plants – which led LSI LASTEM to make a new ad hoc probe, available in the catalogue, for the continuous monitoring of temperature and oxygen in pipelines.
Timely interventions thanks to the new LSI LASTEM probe
In detail, if the oxygen level in the air is below a certain threshold the new LSI LASTEM solution for real-time monitoring allows prompt intervention in order to restore optimal conditions for a correct bio-fermentation process.


The benefits
- Ultra compact design
- High resistance in highly corrosive environments
- Ease of installation
- High measurement accuracy thanks to the experience and know-how of LSI LASTEM in the field of industrial composting plants
Alessandro Sola of Secit Impianti states: “The data relating to temperature and oxygen represent an extremely important indication of the progress of the composting process for plant managers. However, the conformation of the pipes that lead the air to the matrix does not always allow the installation of standard solutions. In this way, the support of the LSI LASTEM technical team proved invaluable in the co-design of a sensor with reduced dimensions, which could also be installed in the opposite direction to the air flow, without compromising in terms of the quality of measurement.”
