EXPERIMENTAL TESTING
EXPERIMENTAL TESTING IN SUPPORT OF ENVIRONMENTAL DECONTAMINATION PROCESSES
TESTS ON DECONTAMINATION PROCESSES OF PHYSICAL-CHEMICAL NATURE (ISCO TEST, PROVE DI HEAT DESORPTION, ETC.)

BIOREMEDIATION TESTS.
Aerobic and anaerobic tests on different matrices (waters, soils, mud, etc.) and for different types of pollutants, by means of micro-scale simulation of the bioremediation processes associated with decontamination technologies in-situ and ex-situ. The tests are carried out using consolidated technical scientific protocols of provisional character on the implementation of simulated processes through chemical and microbiological analyses, elaborated in a detailed final report.
  • Feasibility test: assessment of the capacity of the autochthonous bacteria component to reduce the presence of organic pollutants, removal rates and times envisaged in aerobic and anaerobic conditions.
  • Bio-stimulation testing of the autochthonous bacterial component by adding nutrients, oxygen, electron accepters and donors in aerobic and anaerobic conditions.
  • Bio-magnification tests with addition of specific micro-organisms and stimulation of bacterial growth (oxygen, nutrients, electron accepters and donors) in aerobic and anaerobic conditions. Experimental testing for the optimization of industrial processes.
MONITORING OF THE EMISSIONS OF BIOGAS IN DUMPS FOR HAZARDOUS AND NON HAZARDOUS WASTE DUMPS
ACCUMULATION CHAMBER TECHNIQUE.
The investigation methodology is based on monitoring the emissions of biogas into the atmosphere, for the purpose of rationalizing the management of operating and post mortem waste dumps. In particular the objective is to elaborate maps of Methan and Carbon Dioxide isoflux that enable the identification of the areas with greater emissions referable to the areas of week surface cover. The work enables us to:
  • rationalize the monitoring of emissions of biogas around the dump and verify the possibility of emissions also from surrounding areas, as required by Leg. Decr. 36/2003;
  • reduce costs for installation of wells that can be made following the isoflux, also optimizing the capturing of the biogas.
  • considerably reduce the quantity of biogas released in the atmosphere.
Description of the method:
Measuring of the flux is obtained by using a portable flux meter (“accumulation chamber”) equipped with infrared detector that enables you to measure the concentrations of CO2 and CH4 up to the order of ppms. From a regular flux measurement, in relation to the pressure and the temperature we can determine the volume of the biogas emitted in 2sq.m. and consequently the total volume of all the dump on a daily basis. The measuring points will be geo-referenced through the use of a GPS and subsequently copied on cartography. The data collected will be re-elaborated in statistics for the purpose of obtaining an aerial representation of the flux. Subsequently the:
  • maps of the distribution of o2 and CH4 fluxes by means of dedicated software;
  • technical report
