Environment and risks prevention issues are a major stake in our society. The Rhône-Alpes region has
 
-
understood that very early, especially through the importance of its chemical and nuclear activities.
 
-
Industrial wastewater treatment permits their reuse in industrial use and improve their quality, enabling
 
-
compliance with discharge standards. Various processes are currently implemented to clear the wastewater
 
-
from its contaminants (e.g. biological, membrane liquid-solid separation, physical, chemical and thermal
 
-
processes). One of them is bioremediation.
 
-
It embraces processes that use microorganism metabolism to remove pollutants from a contaminated
 
-
environment. This rather new approach, the less expensive to put in place, is especially interesting in the
 
-
treatment of poorly contaminated effluents.
 
-
<br/> <br/>
 
-
However, these microorganisms must respect a few criteria: <br/>
 
-
- harmlessness towards the environment and human nature,  <br/>
 
-
- easiness of cultivation, <br/>
 
-
- tolerance to treated pollutant(s), <br/>
 
-
- ability to be separated from the treated effluent. <br/>
 
-
 
-
<br/>
 
-
 
-
It is in compliance with this latter requirement that lies our project. In fact, the immobilization of bacteria on
 
-
a solid support makes it possible to retrieve more easily the residue in treated wastewater.
 
-
The activity of modern nuclear power plants with pressurized water reactors generates radioactive
 
-
effluents that contain among other things radioactive cobalt.
 
-
The tubing of the cooling circuit is made of a steel alloy rich in stable cobalt (59Co).
 
-
Undergoing neutron bombardment coming from the reactor, this stable cobalt
 
-
changes into its radioactive isotope, cobalt 60 (60Co).
 
-
The capture of this metal is interesting on a sanitary point of view, because it
 
-
represents a danger under both its radioactive and stable forms (carcinogenic). It
 
-
also represents an advantage on an environmental point of view, in order to avoid
 
-
contamination of waters, soil and groundwater. Even with a short half life,
 
-
cobalt 60 emits high intensity gamma rays, and decays to nickel, which is stable but
 
-
polluting.
 
-
 
-
<br/> <br/>
 
-
Controlled immobilization of radioactive cobalt is both an important sanitary and environmental issue, which
 
-
we intend to solve with an innovative and economical response.
