Treatment methods
|
| Physico-chemical treatment |
Neutralization
|
Precipitation of heavy materials (Pb, Zn,Cu, Ni..)
|
Oxidation reactions( cyanides and nitrites) for de-toxification
|
Reaction of chromium VI reduction for de-toxification
|
Reduction of anions
|
De-emulsification
|
stabilization / solidification
|
Rests on waste fixation and its impermeability to weather conditions when mixed with cement and lime before it is buried in the landfill.
|
| Storage |
1. Devote a collection area of large quantities of reusable materials. |
2. Devote a collection area for collection and storage of quantities of non-reusable wastes in Tunisia to be sent abroad for treatment in specialized institutions (for example those of high temperature incineration).
|
Landfill
|
Water-proof area for underground disposal of treated waste.
|
The methods used for treatment at the facility of Jradou are selected according to the nature of wastes deriving from the various industrial activities in Tunisia as follows :
