| Abstract: | Nitrate content has increased in Morocco, especially in underground water of agrarian areas. Several processes including degradation processes and separation processes can remove nitrate from water. Two separating processes were studied to remove nitrate from brackish underground water: adsorption on industrial animal waste and electrodialysis equipped by anion monovalent membrane. The results show that a desired product water quality can easily be obtained by electrodialysis contrary to chemical adsorption which requires a great reactional surface. |
