Treatment of Petroleum and Flowstation Wastewater Using Combined Coagulants

Abstract

Performance and effectiveness of single and combined coagulants in the treatment of petroleum and flow station wastewater has been studied. In this study, samples of petroleum and flowsation were treated separated with Barium Chloride, Iron (ii) sulphate, Magnesium Oxide and then with mixtures of different chemicals.  Standard methods  for examination of water and  wastewater was used in the analysis of some important physico-chemical parameters.  The results of the  analysis of all the parameters in the petroleum  and flow station wastewater samples treated with six different types of coagulants  shows significant changes and variations in the level of virtually all the parameters in the treated samples when compared with that of the blank.The combined chemical coagulants exhibited a high capacity to reduce the pollutants to recommended effluent limits with  the mixture of Magnesium Hydroxide and Iron (ii) Sulphate been the most effective coagulants. The result revealed that average value of all selected parameters showed variation from points A to F. However, these variations are not statistically significant with F (0.068019) being less than Fcritical Keywords : Petroleum, Flow station, Wastewater, Coagulants, ANOVA DOI : 10.7176/CPER/62-04 Publication date: January 31 st 2020
