Filter media for a drum filter

A system for attaching a filter media to a cylindrical drum filter, the drum filter comprising a plurality of annular frame members, each annular frame member having a circumference with a first circumferential edge and a second opposed circumferential edge, the plurality of annular members being coaxially spaced from one another by a distance, the plurality of annular frame members defining a cylindrical periphery and an inner cylindrical filter space, the filter medial comprising:

• a filter sheet having a length dimension and a width dimension, the length dimension having a first end and a second end, the width dimension having a first side and a second side, the first side defining a first edge and the second side defining a second edge, wherein the width dimension approximates the distance between the annular frame members, and the length dimension approximates the circumference of the annular frame members such that the filter media sheet is configured to span the distance between two coaxially spaced annular frame members to enclose the inner cylindrical filter space;
• a first engagement strip extending along the first side of the filter sheet from the first end to the second end, the first engagement strip having a cord portion located adjacent the first side of the filter sheet and extending outwardly from the first edge, the cord portion having a cross sectional shape, the first engagement strip further defining an attachment tab extending from the cord portion and coextensive therewith, the attachment tab connected to the first side of the filter sheet along the entire length of the first side of the filter sheet;
• a second engagement strip extending along the second side of the filter sheet from the first end to the second end, the second engagement strip having a cord portion located adjacent the second side of the filter sheet and extending outwardly from the second edge, the cord portion having cross sectional shape, the second engagement strip further defining an attachment tab extending from the cord portion and coextensive therewith, the attachment tab connected to the second side of the filter sheet along the entire length of the second side of the filter sheet;
• a first connecting strip receiving the first engagement strip, and a second connecting strip receiving the second engagement strip, wherein the first and second connecting strips each include an outer surface and an inner surface, the inner surface defining a receiving portion configured to receive the cord portion and a body portion configured to engage an annular frame member;
• the receiving portion having a connecting ridge extending upwardly from the inner surface and a terminal end defining a receiving space with a cross sectional shape corresponding to the cross section of the cord portion, the connecting ridge and the terminal end defining a separation space separating the terminal end from the connecting ridge, the separation space receiving a portion of the attachment tab adjacent the cord portion;
• wherein the first connecting strip is configured to be attached along a first circumferential edge of a first annular frame member of the plurality of frame members, and the second connecting strip is configured to be attached along a second circumferential edge of a second annular frame member of the plurality of frame members such that when the first and second engagement strips are fully received in the first and second connecting strips, the filter media extends between the first annular frame member and second annular frame member and along the first and second circumferential edges to enclose a first cylindrical filter space.
