ABSTRACT:
In order to maintain the uniformity of distribution of pores and consistency of pore sizes in a ceramic body used in treatment of biologically active liquor such as wastewater, there is provided a composite body consisting essentially of porous ceramic material having a thin layer of biocidal materials attached to the boundaries of the exposed particles of ceramic in a shallow layer facing the liquor. The layer of biocidal material is of microscopic thickness so that the porosity of the ceramic is preserved and biofouling which would otherwise prevent efficient operation is inhibited. The apparatus is useful as a bubble diffuser in the aeration of wastewater liquor.
