Process and plant for the processing of hazardous waste with Chromium content in six non hazardous waste

摘要

Process and plant for the processing of Hazardous Waste containing Chromium Six as a contaminant in non hazardous waste that can be stored without Special Care and will be degraded in the environment without time limits.The process basically consists in a grinding, Extraction of Chromium Six in Liquid phase and under controlled conditions of agitation, temperature and time, followed by Reduction, transform the Chromium in Chromium Six three and its subsequent precipitation of Chromium as tritoxido For Gasification.The resulting Solid transformation process, can be used as raw material for the production of Refractory bricks or for the manufacture of Bricks used in construction, through a process that is not included in this description.
