Environmental Study For The Role Of Some Bacterial Species In Wastewater Treatment

Abstract

1. aureus, bacillus sp, P. putida, P. aeruginosa, and Micrococcus luteus are among the bacterial isolates that will be examined in this research for their potential to lower the levels of certain pollutants in wastewater collected from the final settling ponds regarding the central wastewater treatment plant (Almamierh) in Hilla city. According to the findings, pH values found in this work fell between 6.8 to 7.6, which is within typical limits. A few species recorded somewhat lower oxygen concentrations, but overall, the values have been similar to those in the control. While all of the bacterial species in the presented research performed exceptionally well in reducing the alkalinity values, some of them did better than the control in terms of electrical conductivity as well as dissolved solids removal. In comparison with control, several bacterial species showed a slight effectiveness in removing chloride and a better removal rate of magnesium and total hardness, yet were ineffective at lowering calcium values. Bacillus sp. had the highest rate of nitrate removal, while phosphate had a slightly lower removal percentage.
