Abstract
Recently modern methodologies allowed the improvement of conventional bioventing strategies in an engineering technology known as smart passive bioventing (S-PBv). The latter is an increasingly used application to reduce the concentrations of organic contaminants below the relative value of contamination threshold concentration (CSC). The S-PBv exploits the natural fluctuations of atmospheric pressure, which allow air to enter into the subsoil, to facilitate natural remediation processes. In this way, the efforts in terms of economics resources in the remediation process are minimised, the risk of pollutants volatilization is drastically reduced, and the degradation favoured by microorganisms is promoted. Our study aims to provide the essential information to plan a series of in situ tests (pilot test) to verify the applicability of this remediation technology, through the use of intelligent sensors designed and engineered using open-source hardware and software.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
