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 ef...

청구항

A ceramic body for use in treatment of liquor which is biologically active nd which is made by the process comprising the steps of bonding a mixture of ceramic material particles with a binder to form a porous body having pores defined by the boundaries of said particles, said body having at least one surface facing said liquor, physically bonding to said boundaries in a shallow layer of said body defined on one side by said one surface a microscopic layer of biocidal material which inhibits the formation of slime or other organic growth.
