Industrial waste coal fly ash, containing hazardous metal oxides, poses potential threats to
the environment and humans. Efficient recycling of such kind of solid state waste is highly
desired yet still challenging. This work addressed waste-to-resource fabrication of a highly
porous whisker-structured mullite ceramic membrane for separation of simulated oil-in-water
emulsion wastewater by recycling of waste fly ash and natural bauxite with addition of WO3.
The formation and characterizations of membranes were systematically studied including …
