Abstract
The asbestos waste neutralization device (10) comprises: an acid tank (23), a vat (16) containing a diluted acid solution, in which waste containing asbestos is dipped, with this solution neutralizing the asbestos waste, a filtration unit (21) to separate, at the end of the neutralization reaction, the solid inert waste from the liquid phase of the acid solution, a regeneration unit (22) for the attacking acid solution, which adjusts the hydrogen potential of the extracted liquid phase by adding concentrated acid contained in the acid reservoir, and means for transferring the regenerated solution into the vat.

An asbestos waste neutralization device, that comprises:
- an acid tank,
- a vat containing a diluted acid solution, in which waste containing asbestos is dipped, with this solution neutralizing the asbestos waste,
- a filtration unit to separate, at the end of the neutralization reaction, the solid inert waste from the liquid phase of the acid solution,
- a regeneration unit for the attacking acid solution, which adjusts the hydrogen potential of the extracted liquid phase by adding concentrated acid contained in the acid reservoir, and
- means for transferring the regenerated solution into the vat.
Method for neutralizing asbestos waste, that comprises the following steps:
- dilution of acid and filling of a vat with a diluted acid solution that neutralizes the asbestos waste,
- immersion of waste containing asbestos,
- neutralization of the asbestos waste in the vat,
- filtration to separate the liquid phase after the asbestos waste has been neutralized,
- regeneration of the acid solution, which adjusts the hydrogen potential of the extracted liquid phase by adding acid contained in the acid reservoir, and
- transferring the regenerated acid solution into the vat.
