Abstract
A filtration system having an in-line filter cartridge with the inlet at one end of the filter cartridge and the outlet at the opposite end of the cartridge. The filter cartridge is connected to the cartridge mounting on the fluid conduits via quick-disconnect couplers with built-in automatic water shutoff capability which enables the filter cartridge to be installed and removed in a horizontal movement. A recirculating bypass is provided in the system which includes a pair of bypass branch lines to recirculate the fluid and prevent trapped stagnant water in the bypass lines. In a shown preferred usage, the filtration system utilizes a filtration cartridge and mount to allow filter cartridges to be easily mounted upon and removed from automatic beverage dispensers.
