A filtration membrane is provided. It comprises a porous support substrate and a porous active layer on top of the support substrate, wherein the active layer is formed of a network of interconnected, randomly arranged ceramic splats with ceramic particles occupying interstices between the splats, and wherein free spaces between the particles define a network of interconnected pores extending through the thickness of the active layer. There are also provided a method of filtering a feed using the membrane and a method of manufacturing the membrane by suspension plasma spraying.
