Effective Regeneration of Flue Gas Wastewater by One-Step Hydrothermal Removal of High Concentrations of Nitrate and Sulfate
Wet flue-gas purification in non-ferrous smelting facilities consumes large volumes of fresh water and generates wastewater rich in sulfate and nitrate. On-site recirculation of this wastewater is currently limited by progressive nitrate accumulation, because no conventional single-step technology can simultaneously re...
