Treatment Technologies of Hydrocarbon Contaminated

Several industries such as petroleum petrochemical textile primary metal operations metalworking waste collection and transportation etc. generate a large volume of wastewater varying in composition and contaminates concentration. Generally hydrocarbons contaminated water/wastewater mean fuel lubricating oil grease crude petroleum tars animal fats vegetable and mineral oils light and heavy fuel as well as their mixtures which are insoluble or poorly soluble in water. Many technologies are available for the removal of hydrocarbon from water/wastewater such as physical separation dissolved air flotation biological membrane adsorption chemical separation advanced oxidation processes and chemical oxidation. This chapter presents a brief review of different technologies used to remove hydrocarbons from industry wastewater. After that it focuses on adsorption and biological treatment technologies to remove the hydrocarbon from water/wastewater.
