A garnet settling/filtration system for use with a plurality of machine tools such as a water jet cutting machine is described. The garnet settling/filtration system comprises a settling tank, which utilizes a removable, disposable settling weir, which is received therein. The settling weir drops into the settling tank and provides an over-under flow system through which the garnet slurry must travel. As the flow of the slurry travels over and under the incorporated series of baffles, the garnet particulate settles out on the bottom of the liner. Once the liner has reached its maximum holding capacity, a series of incorporated, reinforced removal loops located near the top of the liner allow for the easy and quick removal of the liner and the settled-out particulate from the settling tank. The liner can then be discarded and a new one replaced in a matter of minutes, thereby reducing downtime of the machine.
