METHOD AND STATIONARY OR MOVABLE DEVICE FOR NEUTRALIZING AND RECYCLING ASBESTOS WASTE
An asbestos waste neutralization device, that includes an acid tank and a vat containing a diluted acid solution, in which waste containing asbestos is dipped, the diluted acid solution neutralizing the waste containing asbestos during a neutralization reaction. The device further includes a filtration unit to separate, at the end of the neutralization reaction, solid inert waste from a liquid phase of the acid solution, and a regeneration unit for the liquid phase of the acid solution, which adjusts the hydrogen potential of the liquid phase of the acid solution by adding concentrated acid contained in the acid tank. In addition, the device includes an attenuation sensor for regenerated liquid phase of the acid solution from the regeneration unit, and a selective precipitation unit for the regenerated liquid phase of the acid solution, depending on the degree of attenuation the attenuation sensor senses.
