ABSTRACT:
A modular table filter for a circular horizontal rotating table filter includes a number of sections which may be assembled on the support frame thereof. The sections are annular-sector-shaped and, when assembled, form an annulus on the table filter. Each section, in turn, may be broken down into an outer subsection and an inner subsection. Filtration fabric, or textile, may be placed on top of the outer subsection, and secured therein by the inner subsection, which is designed to lock thereinto. Alternatively, each section may be an integral annular-sector-shaped frame having a peripheral groove or channel. Filtration textile may be placed on top of the frame, and over the groove or channel, and wedges driven thereinto to hold the fabric tautly across the frame. The modular table filter greatly simplifies the replacement of the filtration fabric, as the sections holding fabric needing replacement may be removed easily and replaced by ones having fresh filtration textiles without the need for isolating the table filter for an inordinately long time.
