Bioremediation of Wastewater by Using Bacteria
An Experimental Study at Tigris River
Keywords:bioremediation, wastewater, bacteria, physico-chemical parameters
The Tigris River holds great importance in the Middle East, as it traverses multiple nations and has played a crucial part in shaping the region's history and progress. The presence of trace elements in water bodies, such as the Tigris River, can substantially impact the bacteria in the environment. Bacteria are essential for nutrient cycling, organic matter decomposition, and the
overall health of ecosystems. Bacteria are essential in wastewater treatment, particularly domestic waste, due to their ability to perform bioremediation. Bacterial samples from dirty water were gathered to study bacterial potential function in wastewater treatment. Hydrogenophaga pseudoflava and Pseudomonas aeruginosa cultures, two of the most abundant and pollutionresistant bacteria, were isolated from these samples and put to use in the BBM. Sewage effluent samples from untreated sewage water facilities were taken from the Tigris River for this research. Both (i) wastewater treated with a culture of H. pseudoflava and P. aeruginosa and (ii) wastewater treated without a culture of H. pseudoflava and P. aeruginosa (Control) were used to investigate the impact of bacteria on wastewater. Every fifth day, samples were taken and tested by accepted procedures to determine physicochemical parameters such pH, phosphate, nitrate, BOD and COD. Nitrate and COD are most effectively removed by H. pseudoflava, whereas P. aeruginosa reduces BOD and phosphate. The bacterial bioremediation of wastewater is the subject of the current study.
