Paper Title
Greener Cleaner: Sheep Wool Fiber as Renewable Sources for Oil Spill Cleanup

Abstract
Up to now, oil spill pollution is still one of the important issues and challenges worldwide, due to its environmental and economic impacts. It also remains a challenge to environment scientists and technologists. Nowadays, natural and synthetic sorbents are applied for oil spills since this technique is effective, rapid and cost saving for cleaning these pollutions and reducing environmental effects. However, there are several works that have been conducted on using natural adsorbents in the removal of petroleum oils such as crude oil and non-petroleum oils like used cooking oil. In this study, sheep wool (SW) fibers has been selected as a natural renewable source for oily wastewater treatment using static and dynamic systems. The effect of duration, contact time, and wool dose on the oil sorption capacity and removal percentage during static system sorption were investigated and maximum adsorption capacity and removal percentage for 1 g sorbent in 100 ml water containing 9.06 g of used oil using 250 ml glass beakers were found to be 8.89g/g and 98.12%, respectively. From the analytical point of view, each experiment was performed three times under the same conditions and the average results were taken. The adsorption capacity of the dry system was also evaluated and the maximum adsorption capacity obtained was about 26.8g, which reached a duration of 72 hr. At the dynamic system, the following results are obtained. The sorption removal of oil from water-oil system was still almost constant until breakpoint was reached, which was 99.2%, while the sorption capacity at breakpoint was found to be 14.8 g/g, when the flow rate value was 20 ml/min. The column having an ID of 3cm and the height of 25cm, with sorbent mass of 2 g, influent initial concentration of 9.06 g/100 ml (10 ml oil: 100 ml water), and flow rate 20 ml/min could treat 1800 ml of oily wastewater at breakthrough. From the economic point of view, the operating design conditions of 20ml/min flow rate and initial influent concentration of 9.06 g/100 ml were selected as the best conditions of adsorption rate for oily wastewater treatment using packed bed column. These results also indicate that sheep wool fiber can be used without activation and any previous chemical treatment for oil spill cleanup. Keywords- Adsorption, sheep wool, static system, used cooking oil, packed bed column
