Treatment of Oil-Water Emulsion by Adsorption onto Activated Carbon

This is a final year Chemical Engineering project on "treatment of oil-water emulsion by adsorption onto activated carbon" and the main aim of this project is to examine the removal of oil from oil-water emulsions by adsorption powdered activated carbon (PAC). As emulsified oil in wastewater constitutes is a severe problem in the different treatment stages before disposed of in a manner that does not violate environmental criteria. This projects looks into it and will suggest the way to remove oil from oil-water. You can also subscribe to FINAL YEAR PROJECT'S by Email for more such projects and seminar.

Oily wastewater is wastewater with oils and fats, which come from various industries in production processes. Waste oil and any oil containing wastes have a high potential to pollute and degrade the environment especially water and soil. As such, they represent a major environmental problem. To protect the environment, oily wastewater treatment is unavoidable. One commonly used technique for remediation of petroleum contaminated water is adsorption.

This project shows that adsorptive property of the adsorbent is altered by different factors and give information about the ability of the adsorbents to adsorb oil. This project also studies the effect of contact time, the weight of adsorbent and the concentration of adsorbate on the oil adsorption.

Oil removal percentages increase with an increase in contact time and the weight of adsorbent and decrease with increase in the concentration of adsorbate. Equilibrium study shows that the Freunlich isotherm was the best-fit isotherm oil removal by powdered activated carbon.


Adsorption is a separation process in which gas liquid molecules are adsorbed on the surface of an adsorption solid. There is a variety of adsorbents. The most common are Activated Carbon, clay, silica, alumina, and zeolite. Removal of petroleum hydrocarbon polluted groundwater using of activated carbon was investigated, and it was recommended that powdered activated carbon is more effective in the treatment of groundwater then granular activated carbon.

The results of this project shows that the studied adsorbents can efficiently adsorbed the petroleum hydrocarbon from the oil-water emulsion in water. The result of this study clearly demonstrates the importance of choosing the optimum adsorption parameters to obtain high adsorption rate of hydrocarbon, which is essential for any practical application of adsorption process.
