Apparatus and method for treatment of aqueous waste material

Abstract

An apparatus and a method for handling aqueous waste material by boiling are disclosed. An outer vacuum (Vo) is applied in a container (100) outside a single-use waste bag (10) received in the container (100) to hold the waste bag (10) against an inner sidewall (104) of the container (100). An inner vacuum is applied inside the 5 waste bag to lower the boiling point of a waste material therein. The inner vacuum is lower than or equal to the outer vacuum. While applying the inner vacuum, water is vaporized from the waste material to produce a water-reduced waste residual. Vaporizing is accomplished by heating an inner sidewall (104) of the container and by heat transfer from the heated inner sidewall, through the waste bag, and to the 0 waste material in the waste bag. A full waste bag with the waste residual therein is eventually removed from the container.
