TY - JOUR N2 - The present study was to reflect the use of some bacteria in the treatment and removal of pollutants in three selected wastewater sites, including a vegetable oil plant (viz. Al-Etihad Food Industries), the main wastewater treatment station in the city of Hila, and Al-Hila River water from October 2019 to January 2020. The bacterial isolates identified in these three sites were Klebsiella pneumoniae, Escherichia coli, Enterobacteria cloacae, Pseudomonas aeruginosa, Thalasobacillus devorans, Acinetobacter baumannii, and Bacillus subtilis. The molecular study of the bacterial isolates involved the detection of bacterial genera using the polymerase chain reaction (PCR). The results showed that water had a variable nature, depending on the substances in it. It recorded varying chemical and physical property values, ranging between 6.36 and 7.82 for pH and from 2500 to 7100 mg∙dm–3 for total alkalinity. Additional values were 713–2051 μS∙cm–1 for electrical conductivity (EC), 5.90–9.80 mg∙dm–3 for chemical oxygen demand (COD), and 480–960 mg∙dm–3 for total hardness. The given values were also 0.20–0.65 μg∙dm–3, 0.03-0.23 μg∙dm–3, and 0–107 mg∙dm–3 for nitrite (NO2), phosphate (PO4) oils, respectively.
