Integration of electrodialysis with bipolar membrane into technology of treatment of extra wastewater containing sodium sulfate

Popis výsledku v původním jazyce

Sodium sulfate is a common waste material which can be produced in many chemical processes. Typical source of sodium sulfate wastewater is the process of beneficiation of uranium ore. At present, the sodium sulfate wastewater generated in this process isdominantly treated by combination of evaporation and crystallization eventually with integrated membrane processes such as electrodialysisand reverse osmosis. However electrodialysis with bipolar membrane is a modern alternative which is capable to improve the efficiency and environmental sustainability of the process. The process allows to recovery sodium hydroxide and sulfuric acid from corresponding waste salt. This work is focused on analyzing the possibility of reusing the products of electrodialysis with bipolar membrane back into the technology of benefication of uranium ore. It was found that the efficiency of the process is dependent on considered reuse location in the leaching technology with different requirements for their
