Název v původním jazyce

Increasing the concentration of products from electrodialysis with heterogeneous bipolar membrane

Popis výsledku v původním jazyce

This paper focuses on the description and evaluation of laboratory experiments aimed at searching ways to increase the maximum achievable concentrations of sulfuric acid and sodium hydroxide produced by electrodialysis with bipolar membrane from wastewater containing sodium sulfate. Experiments were performed using a laboratory test unit EDR-Z/10-0.8 (MemBrain, Czech Republic) operated in a standard configuration with monopolar membranes as well as in the arrangement with bipolar membranes. In doing so, the acid and hydroxide solution produced in the three-chamber arrangement were further concentrated using standard electrodialysis and alternatively was tested a four-chamber arrangement with bipolar and protective membrane. Both studied methods allow obtaining products of higher concentration. As shown particularly preferable is to use classical electrodialysis with monopolar membranes. This method allowed up to a twofold increase in the maximum achievable concentrations of both acid and base.
