A comprehensive study of SiO2 grown by chemical vapor deposition is conducted on soot coated copper mesh, from which an excellent superhydrophobic-superoleophilic filter mesh is demonstrated using the structure of nano-fibered network. A dynamical model of "flow-guided dehydration" including the microscopic interplay between "flow-induced diffusion" and dehydration is presented. Furthermore, we present a device based on tubular separator to purify oily wastewater that is very much like tap-water delivering in daily life, which does not cause the problem of water blockage.
