Abstract
A disc filter sector having an improved attachment system includes a sector base and a sector neck. The sector base includes stiffening members that extend through the sector base and include an attachment end, such as a threaded fastener or region, at the neck mating end of the sector base. The sector neck includes a hold down member proximate the base mating end of the sector neck. To attach the sector base to the sector neck, a mating attachment member, such as a bolt extends through the hold down member of the sector neck and engages with the attachment end of the stiffening members. In one embodiment, the stiffening members, attachment end, and mating attachment members are disposed outside of the flow regions in the sector base and sector neck.
