ABSTRACT:
An ion exchange water purification apparatus in a unitary housing which makes use of gravity and a manometer effect to flow water through the water treatment beds. The apparatus has an untreated water reservoir at the top, untreated water flows by gravity and the manometer effect through a series of three water treatment beds containing carbon, cation exchange resin and anion exchange resin, respectively. The media in each water treatment chamber is in cartridge form and may be easily removed through the removable top of each water treatment chamber. Treated water from the final water treatment chamber is collected in a reservoir within the housing below the untreated water reservoir. The three water treatment chambers are located within the treated water reservoir to economize on space. The pressure in the water treatment chambers and the treated water reservoir is equalized with the pressure in the untreated reservoir by manometer vent tubes so that as long as there is water in the untreated water reservoir, the treated water reservoir will remain full due to gravity and the manometer effect.
