Bioremediation of Oilfield Produced Water using Rotary Bio-Reactors Cultured Bacteria and Fungi: A Case Study of a Niger Delta Oilfield

  • Abstract:
  • Physicochemical analysis and quantification of oilfield produced waters generated at the studied location in Port Harcourt, Nigeria, reveal an array of oilfield effluents. The water samples studied were originally acidic until first neutralisation at the API Separator Station before being discharged to the Bioremediation unit. The concentrations of heavy metals in the samples were generally too low to detect. For example, Arsenic, Mercury, and Vanadium were not detected in the water. Hydrocarbon concentrations were low, except in the water samples collected after skimming from the API Separator Station in the fourth, seventh, and eighth weeks. This resulted in high Oil and Grease values of 65, 30, and 25 mg/l, respectively. The mean oil and grease value recorded after bioremediation was 2.28 mg/l. Total Dissolved Solids (TDS) in the water samples were low, correlating with their low ionic content. The conductivity values followed the same trend as the TDS values. Phenol, MEA, Sulphide, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Ammonia and Cyanides were all converted or degraded by almost 100% through bioremediation.
