Field feasibility study for biological remediation technique? It is "feasible"
Project managers and site owners are often scared of remediation biological techniques. They have all kinds of uncertainties on time, cost, the final achievement that physical-chemical techniques or thermal technologies don't have.
We are not speaking of Monitored Natural Attenuation, and Source Natural Depletion evaluation that could take place just in particular cases (no receptors at risk, evaluation of lines of evidence). Here we are in the field of ACTIVE remediation, with the so-called enhanced bioremediation.
Enhanced bioremediation is basically to create the best conditions for the right bacteria to do the job for us. Those conditions comprehend pH modifiers, nutrients or co-nutrients, oxygen or air, and humidity just to list the most important ones.
Wonderful? Yes, it is! Microorganisms do the job for us, no impacts of heavy trucks, bulldozer on well-being, and less greenhouse gas emissions, no or less impact on climate change.
Bioremediation does not happen by itself. It should be enhanced as we already told. It is needed a
- Desk study on the basis of available information on geological and hydrogeological conditions and contaminant characteristics and behavior.
- A laboratory test, bringing some soil from the source area in the laboratory and evaluating biodegradation time in controlled condition (temperature, microcosms and so on)
- Field study. That's the bigger problem....how may you evaluate the effectiveness of biological techniques?
One of the possible answers was prepared by TB TESECO BONIFICHE, a small-medium enterprise with its headquarters in Pisa that works worldwide. Its prototype is really a landfarming remediation at a small scale, that could then be scaled up to a bigger dimension. Have a look at the following video in Italian (subtitles in English).
Interesting, isn't it?

4 年Trovo sia un bel sistema tecnologico innovativo, che sfrutta come teoria di base la scienza dell'ecologia microbica applicata alla bonifica-Bioremediation di siti inquinati. Interessante qsta tecnica perche a differenza della decontaminazione di bonifica svolta attraverso soluzioni chimico-fisiche,, qsta tipologia di tecnica Bio, lascia residui zero nel comparto matrice suolo (e dunque, potrebbe nel tempo restituirci di nuovo una matrice suolo da usufruire o meglio adibire per uso agronomico). Ovvio,, andando meglio a studiare come minizzare la pericolosita che potrebbe presentarsi per gli operatori che metteranno in essere qsto tipo d'impianto, nonche' per tutti quelli che casualmente potrebbero averci contatto,, dal subire una contaminazione batterica nociva e impattante per la propria salute fisica (perche sappiamo pure che qste tipologie di microrganismi non tutti sono innoqui per la salute dell'uomo). Grazie, trovo interessante sistema.
