Assessing the efficiency of CPU and use of bacteria in dynamic removal of copper and lead


The faculty of science for women witnessed the discussion of PhD thesis entitled (CPU efficiency assessment in Diyala Company for electrical industries and the use of bacteria in dynamic removal of copper and lead) submitted by the researcher Sahira Hussain Hassan Ali al-Khalidi at the department of biology. The study dealt with evaluating CPU of the residual water treatment unit in Diyala Company for industrial and household electrical industries through the use of three types of bacteria to remove the vitality of copper and lead. The findings indicated that CPU is relatively efficient and that reductive sulfur bacteria (SRB) is more efficient in copper and lead adsorption in case of P.aeruginosa and E.coli bacteria where the former was better than the latter also the optimal conditions were at the temperature of (37 m ᵒ Spa pH 4.5) and contact duration was (2) hours while the heavy element concentration was of (200 parts per million). At the end of the discussion, scientific remarks were presented and the thesis has been accepted since it fulfilled the scientific requirements and the committee wished the researcher excellence in her academic and practical life.
