ABSTRACT:
An improved media filtration apparatus includes an upper tank and lower filtrate compartment, filter media interposed between the upper tank and filtrate compartment for filtering dirty liquid as it is communicated from the upper tank into the filtrate compartment, a conveyor for indexing the filter media in the upper tank and a take-up mechanism including a rotatable idler roller assembly including an idler roller for guiding the filter media and being vertically movable in a range of motion actuates a control to start the take-up mechanism when the idler roller reaches a lower limit of its vertical range of motion and stops the take-up mechanism when the idler roller reaches an upper limit of its vertical range of motion.
