Abstract: A process for cleaning of waste water from calcium nitrate (CN) production is described in this study. Electrodialysis (ED) was used in the process. A pilot ED module was tested with real waste water containing CN. Tests were carried out both in batch and in feed&bleed mode. Concentration at the beginning of the batch test was 20 g/L of CN and a dependence of salt removal on concentration was obtained from results. Concentration of the treated solution in feed&bleed was in the range 0.8 – 80 g/L of CN and it demonstrated to achieve concentrate stream with concentration higher than 240 g/L of CN. All results from the pilot tests were useful for a design of an industrial ED technology in capacity of 200 m3/d.
