everal methods have been proposed for desalination of saline water which can be classified into two main groups of membrane processes and thermal processes. There are other methods to reduce saline water, the most important of which is bioremediation such as phytoremediation. Halophytes are plants that can tolerate the concentration of elevated salt, which common plants are often not able to survive. In this study, desalination from saline solutions were studied using two halophytes ( Salicornia persica L. and Quinoa Chenopodi um Willd.). Salicornia plant was planted using hydroponic culture system at three levels of salinity (2, 8 and 14 dS/m) with two plant densities (8 and 16 plants) for different periods (10, 20 and 30 days). Three replications were conducted for each salinity level and the Electrical Conductivity (EC) parameters, Calcium, Magnesium, Sodium and Chloride ions and their concentrations were determined before and after treatment. The results indicated that the plants with a density of 8 in solutions with Electrical Conductivity of EC~2 dS/m (Marginal Water), EC~8 dS/m (Brackish Water) and EC~14 dS/m (Saline Water) decreased 14%, 14% and 17%, respectively for duration of 30 days and for plants with a density of 16, the related EC decreased 10%, 17% and 20%, respectively. Also, Calcium, Magnesium, Sodium and Chloride ions decreased up to 43%, 26%, 24% and 23%, respectively depending on the level of salinity and the type of condensation. Quinoa plant was also cultivated using hydroponic system at three levels of salinity concentrations (2, 8 and 14 dS/m) with 15 plant densities for different periods (15 and 30 days) with three replications. The results indicate that the Quinoa plant in saline solution with Electrical Conductivity at levels of EC~2 dS/m (Marginal Water), EC~8 dS/m (Brackish Water) and EC~14 dS/m (Saline Water), decreased up to 5%, 8% and 9%, respectively during 30 days. Also, Calcium, Magnesium, Sodium and Chloride ions decreased up to 10, 8, 6 and 7 percent, respectively depending on the salinity level. According to the results of this study, Salicornia plant has a greater potential for desalination compared to the Quinoa plant and can be used to reduce salt from unconventional waters such as saline water and saline wastewater.
