Sulphates content reduction in industrial waste water by means of electrodialysis

Popis výsledku v původním jazyce

High TDS (total dissolved solids) levels in industrial wastewater can pose significant challenges. Nowadays, companies are increasingly pressured by regulations to meet stricter TDS emission limits. The high salt content in wastewater is often caused by the use of acids during production processes (e.g., HCl, H₂SO₄) and their subsequent neutralization. Among the most problematic salts to remove are chlorides and sulfates. Chlorides are highly soluble and cannot be easily removed through precipitation or biological methods. Sulfates, on the other hand, are often present in water as calcium sulfate, introduced during the neutralization of sulfuric acid with lime. Although calcium sulfate has low solubility, its concentration can still be high enough to exceed emission limits. This study focuses on the removal of calcium sulfate from industrial wastewater—where sulfuric acid is used in production—using electrodialysis.
