The role of microorganisms in the treatment of wastewater from oil and gas companies

In the wastewater of oil and gas enterprises, destructive microorganisms that destroy petroleum, petroleum products, diethylene glycol (DEG), which have a strong negative impact on the environment, have been separated out and, their physiological and chemical properties have been determined. The microorganisms separated out from wastewater belong to the families Pseudomonas, Bacillus and Aspergillus and have been found to be the only source of carbon in petroleum and petroleum products. Due to the constant influx of organic and mineral substances into biological basins, a high rate of microbiological processes was observed. When the-wastewater from the Mubarak Gas Processing Plant was mixed with domestic wastewater, it was found to be rich in organic and mineral substances. In such an environment, there are sufficient conditions for the growth and development of heterotrophic bacteria and bacteria assimilate water-soluble organo-mineral substances during development.
