ABSTRACT:
An improved media filtration apparatus includes an upper tank for holding dirty liquid and a lower filtrate compartment for receiving liquid from the upper tank through a filter media. A guide roller mounted above the tank guides the filter media downwardly into the tank. A filter media feed mechanism mounting a roll of filter media is mounted adjacent the guide roller. The filter media feed mechanism includes a brake mechanism for stopping and releasing the feed mechanism. A rotatable tension roller movably mounted for generally vertical movement in a range of motion between the feed mechanism and the guide roller is cooperably connected to the brake mechanism for actuating the stopping and subsequent releasing of the feed mechanism and filter media. The brake mechanism is actuable by the rotatable tension roller to release filter media as the tension roller moves upwardly to an upper limit of its range of motion and the brake mechanism is applied as the tension roller moves downwardly to a lower limit of its range of motion.
