| Abstract: | Desalination experiments by means of electrodialysis were carried out with a pilot plant of Soviet origin. Brackish water of the Bulgarian Black Sea coast with different fresh-water concentrations and 135… 700 mg/1 salt was used as the salt water. The applied electrode voltages were 100… 400 V. In dependence on other conditions such as flow rate, temperature etc., there were determined the energy demand (referred to the removal of 1 kg salt) and the desalination effect. A mathematical model for calculating the energy consumption is derived from the experimental findings. |
