Abstract
Systems and methods are disclosed that promote the remediation of contaminated materials that are produced during industrial processes. These systems and methods include heating a material, transferring heat from the material to an industrial process. During this transfer, contaminants may be introduced into the material. These methods may remove the contaminant by treating the material with a surface modified nanoceramic through nanofiltration and/or active sites adsorption/reaction. The surface modified nanoceramic may remove at least part of the contaminant in the material. No cooling required prior to removing the contaminant from the material, which can lead to great energy saving and pollution reduction.
