Question

We wish to desalinate 400 L/min of brackish water containing 1.5 g/L salt to 0.5 g/L salt in an electrodialysis system. The system has 200 cells and the efficiencies are estimated as: ηs = 0.98, ηw = 0.99, and ηm = 0.99. The average resistance of each cell is 0.03 ohms. Determine, (a) The current and voltage (b) The energy required in (cal/L) water (c) The power in kilowatts

Step 1

Salt removed per minute = (Initial concentration - Final concentration) * Flow rate Salt removed per minute = (1.5 g/L - 0.5 g/L) * 400 L/min Salt removed per minute = 1 g/L * 400 L/min Salt removed per minute = 400 g/min Now, we need to find the equivalent Show more…
