dc.description.abstractThere is a great need to keep environment safe from huge threat of contaminants that are spreading at high speed above and below the ground. The main reason evolves from the dramatically increase in the usage of chemicals in many sectors and machinery where oils and fuels are demanding. This paper is based on studying the efficiency of a designed textile sorbent from nonwoven material (made from polypropylene fibers) when it is applied in light oil phase into remediation wells. The following tests were carried: capillary action tests included plain strips, tubular sorbent in oil and weight test (oil only). The absorption and capillary action include test in measuring cylinder (oil on water) and this is last test which reflects nature situation. The trip tests categorized polypropylene materials made of different nonwoven technologies and different properties according to their efficiency in absorbing oil. Two different types of sorbents were compared, completely hydrophobic ECT and ECT U that possesses both hydrophobic and hydrophilic properties. Among each of these sorbents comparison was also done, heavy (high density) against light (low density) samples. The main experimental parameters are the following: time taken for sample to reach maximum capacity, height travelled by oil during capillary action and gram oil per gram textile ratio. It was also interesting to check whether the sorbent sink at the end of experiment. The experimental results showed that ECT and ECT U heavy samples have high oil absorption capacity compared to light samples due to their better retention time. ECT U sorbents have better affinity to oil than to water. In nature simulating tests (test in measuring cylinder) absorption rate is very higher because 200ml oil is absorbed within 5-7 minutes and 396.8 ml within one hour for cylinder with 50mm diameter and 250mm long. The sorbents will not sink if used in nature.cs
