Experimental activities for the study of biodegradation
In the recent years GEEG has carried out laboratory and site activities, in collaboration with Contractors and Suppliers of conditioning agents, in order to measure the kinetic of biodegradation due to the microorganisms spread in the environment. Our research activity is aimed at analyzing the influence on the biodegradation of different factors such as temperature, type of bacteria present in the soil, concentration of the chemical agent and soil type. The development of expeditious measures to be applied directly on site is in progress and some of them are already being adopted, experimentally, with reference to real appliances.
In this study we dealt with the analysis of the effect of metallic iron nanoparticles for the pre-treatment of leachate water from conditioned soils, reproduced in the laboratory. Experimental results showed how nanoparticles can be used as a heterogeneous catalyst for the development of a heterogeneous Fenton process, particularly effective for increasing the biodegradation of the treated leachate.
