Efficiency Study of the Bioremediation Treatment System of Produced Water in Palouge Field

Abstract

This study aims to evaluate the efficiency of the palouge bioremediation system as biological method for the produced water treatment from the oil. The evaluation depends upon measuring of some properties of both the inlet to & outlet from the system & then compares them by the Environmental regulations in Sudan 2002.The study also aims to examine the availability of the optimum Environmental conditions necessary for the microbial growth (mainly bacteria). From the results it has been found that the system has high efficiency according to the oil &phenol (toxic pollutant) content in the outlet which conform to the Environmental regulations in Sudan 2002 for the surface disposal of the waste water. In accordance to the environmental conditions required for optimum microbial growth, it has been found that the average value of both temperature& pH were within the optimum range for the microbial growth, but for the dissolved oxygen value at the inlet sample conform the minimum value necessary for the oil biodegradation by the microbes, but for the dissolved oxygen value at the inlet sample conform the minimum value necessary for the oil biodegradation by the microbes, but for the outlet sample the dissolved oxygen value is very small so it is not enough for the biodegradation process in the front reed beds.BOD & COD values conform the environmental regulations in Sudan and also the decreasing manner in these values indicate the progressing of the treatment system. For the soil moisture content it has been found that the moisture content was within the optimum range for biodegradation. Also from the study it has been found that sodium content present in high quantities at the outlet sample which will cause in the long term bad effect to the soil structure. For the cations (Ca, Fe, and Mg)
