摘要

PURPOSE: A water purifying filter with a serially connected hollow fiber membrane filter unit is provided to delay the replacing timing of a hollow fiber membrane filter and increasing the purifying amount of water.;CONSTITUTION: A filter housing(14) includes an inlet(11), an outlet(12), and a housing cap(13). A hollow fiber membrane filter unit(15) is composed of U-shaped hollow fiber. Hollow fiber membrane cartridges(18a to 18c) are serially arranged in the filter housing, and the hollow fiber membrane filter unit is connected to the upper inner side of the hollow fiber membrane cartridges based on a potting material(16). A hollow fiber membrane guide(19) fixes the uppermost hollow fiber membrane cartridge to the filter housing. Water purifying guides(22, 22a) prevent the mixture of purified water and feed water by being composed of a body part(20) and a purified water transferring path(21).;COPYRIGHT KIPO 2012
