The “odor” problems
The sheds where the matrices are first sorted and then prepared to be treat in our devices are all in depression.
A double-door system allows the trucks to enter and unload directly into the "mouth" of the abduction systems but, at the same time, inhibit from leaving, thus preventing the dispersion of nasty odors outside.
All the internal air, also in order to keep the depression constant, is sent via pumps to the gasifiers and / or plasma torches.
In the case of treatment in the sewage sludge plant, biological deodorization technology will be adopted by means of a biotrickling filter owned by one of our commercial partners. Thanks to this system, the qualities of the counter-current washing are combined with those of a biological filtering system. The operation is similar to that of a percolating filter in which, however, the percolating agent is not the substance to be purified but the purifying agent.
In fact, this is an aqueous solution activated with special microbial strains which metabolize the odorous molecules by setting up on the large surface of the special support.
Biotrickling filters have the advantage of being able to treat high concentrations of pollutants and allow the application of high specific loads with consequent reduction of the volume of the filter bed and of the surface used.
