The study was made to determine the mathematical model for the desalination reactor that depends on algae biological action. The equation proved to obtain removal efficiency of total dissolved solids from saline water by the means of the green algae Scenedesmus species through a continuous flow treatment system. Algae were added to two consecutive reactors in which a 7 days retention time was applied in each. The experiment in the continuous flow was repeated for 4 runs and the average values were taken into consideration. Physico-chemical analysis of growth media was daily determined. Total dissolved solids removal efficiencies measured in the output of both first and second reactors reached around 88% for each and 97% for the overall plant. The results were used to produce the simulated equation for the action taking into consideration the effective parameters. The equation verification was done with error range than field results + 10%. This shows the success of the equation to simulate the system which is a new promising technique to produce suitable potable water from sea water.[Full Text Article]
