“…Oily wastewater, a type of industrial wastewater, often contains hazardous aqueous pollutants. , Prior to discharge, it is necessary to separate the oil/water mixture and remove the aqueous pollutants from the water. While numerous studies have been conducted on oil/water separation, − only a limited number of researchers have focused on exploring materials and technologies that possess the ability to simultaneously achieve both oil/water separation and pollutant purification. − Two approaches, namely, the filter type and particle type, have been proposed for the removal of aqueous pollutants during oil/water separation. In the filter-type approach, the oil/water mixture is first separated, followed by the decomposition of organic matter in the water using a catalyst. − On the other hand, in the particle-type approach, the organic matter is decomposed using a particle catalyst, and then the oil/water mixture is separated using particles .…”

Oily wastewater, a global environmental concern, demands efficient oil/water separation and pollutant removal. Our compressible separator and catalyst (CSC) balls, prepared through sponge etching and metal nanoparticle synthesis, exhibited efficient degradation of dyes of varying sizes, spanning a molecular weight range from 139 to 696 g/mol during the oil/water separation. Control over the distance between catalysts was achieved by incorporating Ag–Pt–Pd catalysts into the sponge skeleton and by adjusting the compression rates. The dispersion of the catalysts improved degradation efficiency for larger dyes, while concentrating the catalysts proved to be more effective for the smaller ones. By optimizing the compression rates of CSC balls, we successfully achieved the effective removal of emulsions of different sizes and precise control of flux. Our CSC ball-loaded system offers efficient and versatile solutions for concurrent separation and purification of emulsions and pollutants with potential environmental benefits.
