Step 5: Bioremediation treatment
Bioremediation to deal with organic contamination (such as hydrocarbons)
This process consists in activating the micro-organisms that are naturally present in the sediments to break down certain organic compounds.
This operation, which is routinely used to remediate both soil and dredged sediment, takes place in an impermeabilised open-air bioremediation unit.
The creation of windrows, operations to turn over the previously dewatered sediment, and the addition of nutrients boost the process.
These two treatment techniques, i.e., phosphation and bioremediation, can be used alone or combined, according to the type of contamination.
