Patent ID: 10626023

Abstract:
There is disclosed a method and an apparatus for reducing the amount of waste, requiring special handling and possible destruction, in a process involving vaporization, in an evaporator apparatus (1-6, V1-V6), of a water solution containing environmentally hazardous substances. A considerable amount of the water content of said water solution is vaporized in a reusable vaporization chamber (2a). At a certain time, the vaporization process is stopped, so that the remaining water content is 70% to 5% of the initial water content. Thereafter, in a second step, the remaining water solution in the reusable vaporization chamber (2a) is transferred into a separate waste isolating container (6), where the remaining water is subjected to at least one further water-reducing process. The remaining waste, including the environmentally hazardous substances, is left in the waste container for separate handling and possible destruction.
