A Low Cost Material for Treatment Wastewater Contained Petroleum Pollution

Abstract

Abstract One of the major problems facing the water environment is the pollution resulting from petroleum, refineries and oil industries which resulting a great danger to humans, aquatic organisms and water resources in the world. In this study, Conocarpus plant was employed as natural adsorbent substance which performed to reduce the concentration of contaminates exiting in the petroleum wastewater. The pollutants that have been removed are phenol, grease and oil. The laboratory experiments using Bach technique. Maximum efficacy of phenols removal was (83.694 %) at pH of (3.7). The highest efficacy of oil and grease removal (99.861 %) achieved at adsorbent mass of (15g), pH (9.77) and time of (120 min.). The Conocarpus plant has been shown to be effective in removing of pollutants (phenols, oil and grease) from wastewater. Efficacy of phenol removing progressed in increasing with adsorbent mass. The acidic pH value contributes greatly to increasing the efficiency of removal for both phenols, oils and grease. Maximum. amount of oil and grease adsorbed in solid phase was (17.369 mg/g). The results demonstrated that Conocarpus plant as natural adsorbent can be efficiently applied in refiners, grease and petroleum industry for eliminating pollution.
