An adapter ring [170] is placed within said recess [102]. The adapter ring [170] has a flange [172] and a barrel [179] extending from the flange [172]. The barrel [179] has an inner wall [180] and an outer wall [182], and is positioned within said aperture [110] such that the outer wall [182] of the barrel [179] is in close proximity with said aperture [110]. The flange [172] comprises an inner surface [173] which abuts the seat surface [101]. The filter plate assembly [1] further comprises a filter cloth assembly [160] comprising a filter cloth [168] having an aperture [168B], and a grommet [168A] fitted within the filter cloth aperture [168B]. The grommet [168A] is configured to align with the adapter ring [170], and comprises a collar [167] having an inner surface [167A] which is bonded or mechanically attached to a first side [188] of the filter cloth [168].
