Cattail fiber is considered as one of the biomasses for oil sorption purposes. In this work, the unique structure and wetting characteristic, as well as the basic mechanisms governing oil uptake of cattail fibers were investigated. Cattail fibers grow in tufts with down-like structure consisting of root, stem, seed and several fibers. A single cattail fiber(More)
Structured cattail fiber assembly was reported as the filter for removing oils from runoff. The oil-wetted filter was recovered by rotational centrifugation and reused in the next filtration. The cyclic filtration behavior of the assembly was characterized by oil removal efficiency, oil sorption capacity, influence of packing density and number of(More)
Highly porous fibrous assembly made by kapok and hollow PET fibers was prepared by the air-laying-bonding method, and used as the interceptor for oils on static and running water. SEM showed that the vast majority of kapok and PET fibers in the assembly was intact and retained their hollow lumens, with the assembly's porosity high to 98.03%. Oil sorption(More)
A depth filtrating system with rotatable and taper-shaped filter column was reported to highly remove and recover oil from wastewater. In the work, structure filters made of kapok fibers were prepared by air-laying-bonding method. The oil removed from wastewater was then recovered from the oil-loaded filter by rotating the filter column, and the resulted(More)
