Kapok oil absorbent fiber as
A natural vegetable fiber kapok (Ceiba petandra ) , assessed its viability as a filter to separate mixed liquids such as mixtures of oil / water. Two types of oils , namely diesel and hydraulic investigated. Several simulation oily water prepared by mixing tap water with one of these oils to produce a binary mixture of oil / water of various percentages of oil , such as 5 % , 10 % and 15% by weight . Packing density filter effect on the dynamics of the separation of oil / water during the filtration process and the quality of the filtrate under investigation . Due to the characteristics of the hydrophobic surface – oleopholic kapok fiber , the water can be filtered through a filter while the oil is maintained , causing the separation of oil from water. Filtration efficiency for removing diesel and hydraulic oil from oily water each achieved more than 100 % and 99.4 % , respectively , indicating excellent performance of cotton in removing oil from oily water . Hydraulic conductivity of the filter to decrease with the progress of the front of kapok oil was found . Filtration rate both water and hydrocarbons decreases with increasing the packing density and oil content filter influential . The kapok filter performs equally well in terms of the total filtrate collected before groundbreaking for two different oils , but could rate dependent viscosity filter . A packing density of 0.07 g/cm3 is optimal for removing diesel and hydraulic oil. In advance , / water , oil / air three stages in the filter layer is a function of the concentration of influent oil , oil type, and packing density filters .
