Abstract
The invention relates to a method for treating a contaminated slurry comprising subjecting the slurry to a treatment wherein contamination is transferred from a substantially solid phase of the slurry to a substantially liquid phase of the slurry.
Claims7
A method for treating a slurry containing at least one of carbon and organic carbon contaminants, the method comprising:
- subjecting the slurry to an ozone treatment such that the contaminants are solubilized and desorbed from a substantially solid phase of the slurry and partially oxidized, wherein the contaminants are transferred from the substantially solid phase of the slurry to a substantially liquid phase of the slurry;
- and
- supplying an amount of ozone to the slurry for a particular length of time and for a particular quantity of a specific slurry species such that a desorption rate of the slurry is greater than zero.
