This specification establishes the criteria for acceptance, prior to installation, of vitrified clay filter block used in trickling filters for the treatment of sewage and industrial wastes. Filter block shall be formed from fire clay, shale, surface clay, or a combination of these materials. Chemical properties such as acid resistance; and physical properties such as compressive strength, and absorption; are detailed.
