Abstract

Up to now, oil spill pollution is still one of the important issues all over the world, due to its environmental and economical issues. It also, remains a challenge to the environment scientists and technologists. Nowadays, removing of petroleum and nonpetroleum spills by adsorbent materials is the most safety and effective process. However, there are several works that have been conducted on using natural and synthetic adsorbent materials such as kenaf fiber, sugarcane bagasse, crumb rubber, polyurethane foam, polypropylene fiber raw wool and cotton, and silica nanopowder, in the removal of oils from water-oil system. In this study, recycled textile fiber (TF) obtained from used tires has been selected and used as a low cost and recycled adsorbent for petroleum and non-petroleum oily wastewater treatment using the static and dynamic systems. The effect of duration, contact time, and fiber 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 TF in 50 ml water containing 4.62 g of oil using 150 ml glass beakers were found to be 4.33 g/g and 94% for cooking oil , and 4.10 g/g and 88.74 % for crude oil respectively at room temperature. The evaluation of sorbent efficiency for only oil uptake which called “dry system” was also studied and the maximum adsorption capacity was obtained about 17 g/g for used cooking oil, and 14.4 g/g for crude oil which reached duration 24 hr . Compressed textile fiber using physical technique to removal oil from the layer oil system was also studied using static system. 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%and 98.5% for used cooking oil and crude oil respectively, while the sorption capacity at breakpoint was found to be 7.53g/g and 6.5g/g for cooking oil and crude oil respectively with flow rate of 20 ml/min. The column having an ID of about 25 mm, with fiber mass of 2 g, influent initial concentration of 9.06 g/100 ml, and flow rate 20 ml/min could treat 2000 ml and 1840 ml of cooking oily wastewater and crude oily wastewater respectively at breakpoint. Although the compressed TF showed lower sorption capacity than uncompressed fiber which about 2.35 g/g. But at the same time, the compressed TF showed that could be used for the storage and transport of recovered oil and the adsorbed oil not leaches out at room temperature for long time. These results also indicated that textile fiber obtained from used tires can be used without activation and any previous chemical treatment for oil spill cleanup.
