Abstract |
|
|
| Desalination of saline water became an obligation., and the measuring of salinity as electric charge as sodium chloride is interfered. A method based on neutron scattering was proposed for monitoring salinity of water during desalination processes. It is based on the use of a fast neutron source (Pu-Be) and thermal neutron detectors. Due to the reaction of fast neutrons with saline water during the desalination processes, neutrons are thermalized by water. Neutron thermalization depends on salt concentrations in water. High density of thermal neutrons inside the irradiated sample, indicate low concentration of dissolved salts and vice versa. Such a working principal was used for monitoring the removal efficiency of dissolved salts in saline water during desalination processes using microorganisms. Biomaterials (fungal organisms) used in desalination of seawater were extracted using well established procedures. The most efficient extracted product of the fungal organism was used to perform real desalination of seawater. The fungal organism was added to a container containing seawater. It was irradiated by fast neutrons, and backscattered thermal neutrons from a certain position in the container were registered continuously as the desalination process proceeds. Results obtained showed that the neutron scattering methods was effective in monitoring the desalination process. The fungal organism used was very effective in precipitating dissolved salts withing several minutes. |
