Process for the disposal of acid wastes combining them with asbestos containing materials and/or concrete
An accelerated process for the complete neutralization of acid wastes, the destruction of concrete and/or the denaturation of asbestos-containing materials (ACMs) includes forming a slurry or suspension by submerging in the acid solution the concrete and/or asbestos-containing materials (ACMs); the concrete and/or asbestos-containing materials (ACMs) cause the acid wastes neutralizing chemical reactions in the slurry or suspension and, at the same time, the destruction of concrete and/or the denaturation of asbestos-containing materials (ACMs). Simultaneously to the chemical reactions, the slurry or suspension is subjected to hydrodynamic cavitation, preferably using an apparatus capable of producing and managing three types of simultaneous controlled cavitation acting in the same space volume, accelerating the chemical reactions taking place in the slurry due also to the simultaneous presence of acid, concrete and/or asbestos-containing materials (ACMs). The concrete and/or asbestos-containing materials (ACMs) are preferably ground and polarized prior to be submerged in the acid solution to form the slurry. The polarization take place, for the really first time, with a cold plasma torch. In addition the slurry or suspension is preferably subjected to hydrothermal treatment, preferably using a reactor which ensures the preservation of the constancy of the ideal physical parameters for the reaction in the physical chemical environment. In this reactor are additivated chemicals, hydroxyapatite and biological substances that have binder/chelating power especially on metals contained in asbestos, especially on magnesium, in order to prevent its reformation. Recovering, at the end of the process, inert secondary raw materials (SRMs) that are non-hazardous to the environment and human health. In addition, this process could be used to produce molecules that are important intermediates of the subsequent reactions/processes, leading to the formation of salts/compounds used as dietary supplements and also in important environmental remedies such as polluted water reclamation and the treatment of heavily polluted soils.
PROCESS FOR THE DESTRUCTION OF CEMENT, ASBESTOS-CONTAINING MATERIAL AND/OR OTHER MATRIX MATERIAL BY SIMULTANEOUSLY SUBJECTING THE MATERIAL TO CAVITATION AND ACID-BASED CHEMICAL REACTION
An accelerated process for the complete destruction of a matrix material, such as a matrix material including cement and/or asbestos-containing materials (ACMs), is disclosed. The process comprises forming a slurry or suspension by combining the matrix material with an acid solution (including, for instance, acid waste, which can also be neutralized by the process), causing acid-based chemical reactions in the slurry that cause the destruction of the matrix material. Simultaneously to the chemical reactions, the slurry or suspension is subjected to cavitation, which synergistically cooperates with the chemical reactions to accelerate matrix material destruction. The matrix material can be ground and polarized prior to being submerged in the acid solution to form the slurry. The slurry can be subjected to hydrothermal treatment. Inert secondary raw materials (SRMs) that are non-hazardous to the environment and human health can be obtained from the process.
