Seawater desalination is a process of obtaining fresh water from seawater. Research on seawater desalination process by using electrodialysis membrane has been done. The aim of this research was to determine the ion transport kinetics in seawater desalination process with electrodialysis membrane. The research of seawater desalination was done in batch process.  The seawater used as raw material has 25000-35000 ppm TDS concentration. Time, temperature, and feed flow rate variation were used as variables. The value of k obtained was 0.315 10-6 m for 5 cm/sec flow rate at 35C temperature and 25000 ppm concentration, and 0.45 10-6 m at 35C temperature and 35000 ppm concentration. The value of kinetics of ion transport in electrodialysis membranes is strongly influenced by the value of ilim. The value of i is strongly influenced by temperature. The results value of k showed that the higher temperature will increase the value of k as well; the concentration had significant influence on the value of ilim; the higher concentration of salt solution will increase the value of ilim and also increase the value of k.
 

Key words: Seawater, ion transport kinetics, membrane electrodialysis
