Abstract

Biodesalination of water is a promising method for treating the salty water due to its environmental friendliness and ability to get rid of the recalcitrant salts. In this study, two types of microorganisms Rhodococcus erythropolis (ATCC 25544, PTCC 1767) and Acidithiobacillus ferrooxidans (ATCC 23270, PTCC 1646) medium supplemented with MG- Sulfur Free Medium (SFM) and the medium PTCC 105. A monitoring for the physicochemical properties of the reaction medium has been shown. A modeling based on the monitored behaviors has been developed based on Artificial Intelligence for both microorganisms. It was found that the optimum operation conditions have been designed by using Definitive method such as mixing speed, temperature, surfactant dose, Oil Water Ration (OWR), pH. Biodesalinatio was shown in this utilization of current objective by setting the minimization of total content of salts as the main objective in the Response Surface Method (RSM). Also, a pathway optimization was designed based on the proposed model and controlling the products of bioreactions. It was found that this theoretical and applied methods can lead to a high efficiency in the treatment of oil.
