Abstract:
1. A method comprising: a) assembling a plurality of ceramic filters having square or rectangular cross-sectional shapes, four outer surfaces and common lengths into an array wherein two or more of the outer surfaces of each filter are located adjacent to outer surfaces of other ceramic filters with removable spacers located between the adjacent surfaces of ceramic filters such that the spaces between the adjacent surfaces are uniform on a work surface; b) removing sequentially one or more of the ceramic filters or horizontal rows of the ceramic filters and removing the spacers between adjacent surfaces until a single ceramic filter remains; c) applying a layer of a cement to the outer surface of the single ceramic filter on the work surface; d) replacing the next adjacent ceramic filter or horizontal row of ceramic filters in the location the ceramic filter or horizontal rows of ceramic filters were removed from, which location or locations place surfaces of the ceramic filters in contact with the cement layer or layers applied to the adjacent surfaces of the ceramic filters; e) sequentially applying layers of cement to the outer surface of a ceramic filter or outer surfaces of a horizontal row of ceramic filters and replacing the next adjacent ceramic filter or horizontal row of ceramic filters in the location or locations the ceramic filter or horizontal rows of ceramic filters were removed from, which location or locations place surfaces of the ceramic filter or ceramic filters in contact with the cement layer or layers applied to the adjacent surfaces of the ceramic filters until all of the ceramic filters are replaced in the same position on the work surface with uniform cement layers located between all adjacent surfaces of the ceramic filters, wherein the work surface moves to a plurality of locations where the system removes or replace the ceramic filters.
