The Phipps & Bird Column Filtration System (CFS) is used to simulate the process of a direct-filtration water treatment plant. The device is an accessory piece of equipment for the traditional Phipps & Bird JarTest Stirrer with Square B-KER²s (not included).

After water samples are agitated through the flash and flocculation stages, the samples are allowed to gravity drain through filter columns producing a simulated "clean" water test sample. A water line from the plant's service line can be connected to the device to backwash the filter columns when loading the granular media or when cleaning the media after a test procedure.

The device consists of a number (4 or 6) of filter columns (2" ID clear PVC) and sets of valves to control the flow of water samples from the sample B-KER²s and service water during the backwash process. All components are mounted on a portable rack with casters. The CFS mounted on the portable rack can be used in the lab or moved to a more convenient location within the treatment plant.
