【 摘 要 】

The goal of this work was to develop a homemade device to desalinate brackish water, using biological material like seeds from different plant species of the semi arid regions. Umbu seeds (Spondias tuberosa Arruda Câmara) were found to be the most appropriate material, removing a higher quantity of salt from the water compared to the other tested materials. The salt content in 1 L of brackish water typical of the region can be removed with only 1 g of the material, if the water is heated to 50 °C and it may also lower the water hardness, achieving drinking water standards.
