Treatment of Wastewater in the City of Tikrit Using Bacteria Pseudomonas Spp

Abstract

The study included the ability of pseudomonas aeruginosa to reduce pollutants in the wastewater of Tikrit under different ventilation conditions (aerobic, anaerobic, facultative) for three treatment periods (2,4,6 hours) and controlled temperature (25 ° C). Physical and chemical measurements of water were performed before and after treatment. The results showed the efficiency of pseudomonsa aeruginosa in the removal of contaminants during the long treatment period (6 hours) in achieving the best results for PO4, NO3, SO4 COD, Zn and Ni in treated wastewater (60.4,43.5,61.4,82.5,87.4, 87.8%). Respectively, with significant differences from other interventions.The results of the study showed the effect of the quality of the bacteria and the different ventilation conditions and the time spent on the treatment in giving the best rates for all studied properties of wastewater and the long period of 6 hours as the best time to reduce all the studied properties.
