A filtration system includes a filter medium that has two side edges. The filter medium is moveable in a longitudinal direction, and at least a segment of the filter medium is used to filter a fluid. Seals are used to seal the filter medium segment's side edges, and the seals are moveable with the filter medium in the longitudinal direction. Consequently, the seal may not need to be raised or deflated during indexing of the filter medium. Additionally, the indexing of the filter medium does not create wear on the filter medium and seal and does not cause distortion or tear of the filter medium.

Filtration system and seal assembly

A method and apparatus for sealing the opposed side edges of a fluid treating belt filter () by employing an inflatable elastic tube (). Opposed sealing surfaces are spaced apart from each other defining a gap there between which can be brought into sealing relationship by activation of the tube (). The tube () being tested prior to and during sealing. Fluid that bypasses the seal are collected for rycycle.

Filter bypass monitoring system

An apparatus and method for circulating coolant liquid between machine tools and a coolant filtering unit through an overhead return line. A small stream of clean coolant is diverted to a flush tank and the tank is pressurized, e.g., with compressed air. Periodic release of the pressurized liquid from the flush tank through the overhead return line flushes deposited chips and other sediments from the return line.
