Abstract: Methods and systems for pre-treatment of sludge and biosolids in preparation for electrochemical valorization is disclosed herein. Such methods can include selecting a sludge source; preparing a slurry, where the slurry comprises the sludge source and an electrolyte; adjusting a pH of the slurry, where the adjusting the pH of the slurry results in the slurry having an adjusted pH in a range between approximately 8 and 13; flowing the slurry through a first electrochemical cell, where the first electrochemical cell enables partial oxidation of the sludge via hydroxyl radicals; and flowing the partially oxidized slurry from the first electrochemical cell to a second electrochemical cell for selective conversion, where the second electrochemical cell includes an anode, a cathode, and a catalyst.

Abstract: A process for the treatment of thick fine tailings that include constituents of concern (CoCs) and suspended solids is provided. The process includes subjecting the thick fine tailings to treatments including chemical immobilization of the CoCs, polymer flocculation of the suspended solids, and dewatering. The chemical immobilization can include the addition of compounds enabling the insolubilization of the CoCs. Subjecting the thick fine tailings to chemical immobilization and polymer flocculation can facilitate production of a reclamation-ready material, which can enable disposing of the material as part of a permanent aquatic storage structure (PASS).

Abstract: A method for treating a water-containing substance, including: mixing a water-containing substance with a solvent at a first temperature to obtain a mixture containing a solid substance and a liquid substance; conducting a first separation treatment of the mixture to obtain the solid substance and the liquid substance; and conducting a second separation treatment of the liquid substance obtained by the first separation treatment at a second temperature to obtain an aqueous phase and an organic phase, the organic phase contains the solvent. The mutual solubility of the solvent and water at the first temperature is higher than that of the solvent and water at the second temperature, so that the separation and recovery of water is achieved by liquid-liquid separation without phase transition in the method for treating a water-containing substance, so the energy consumption can be effectively reduced. The invention further relates to a corresponding device.
