WATER PURIFYING DEVICE AND WATER PURIFYING METHOD

PROBLEM TO BE SOLVED: To provide a water purifying device which uses a plurality of cartridges and can easily be adapted to the cartridges of different structures and/or different numbers, and in which water can easily be taken out in the midway of a filtration treatment for an auxiliary treatment and easily be returned to a cartridge assembly after the auxiliary treatment. SOLUTION: The water purifying device 10 uses a plurality of the cartridges 28 which each contains filter media 162 therein and has a water inlet 70 and a water outlet 72 at the upper end thereof, and which are bound to one another making up a filter assembly 20. Manifolds 34, 80 connecting each of the water inlets 70 and the water outlets 72 so that the water flows through the cartridges in series and/or in parallel are detachably fixed onto the filter assembly. Moreover, the manifold 34 has auxiliary ports 40, 42 for performing an auxiliary treatment of the water in the midway of the filtration and again returning the water to the filter assembly. The device can thus easily be adapted to the cartridges of different structures and/or different numbers by simply modifying the structure of the manifold as desired. COPYRIGHT: (C)2011,JPO&INPIT
