Abstract

PURPOSE:To observe the contamination degree of a hollow yarn membrane by arranging the hollow yarn membrane and activated carbon in a cartridge and setting the upper end part of the hollow yarn membrane to an inlet side and forming the part directly thereabove from a transparent cap. CONSTITUTION:A hollow yarn membrane case 9 having hollow yarn membranes 6 received therein is received in a cartridge 5 and activated carbon 7 is received in said cartridge 5. When a change-over valve 4 is set to a raw water side, raw water can be directly taken out to the outside from a water stopcock 3 through a raw water emitting passage 1c. When the change-over valve 4 is set to a purified water side, the raw water enters the water passing inlet 5a of the cartridge 5 from the water stopcock 3 through an inlet passage 1d and applies water pressure to a check valve 8 to float the same and passes through the activated carbon 7 to adsorb a chlorine smell and a contaminant by the activated carbon 7 while the treated water is allowed to flow through the hollow yarn membranes 6 from the upper end parts thereof to remove various bacteria. By this method, the cartridge can be made inexpensive.

The body 1 is detachably attached to a faucet 3 via a connecting portion 2. The body 1 has a central passage 1a, in which a switching valve 4 is housed, and the faucet communication passage 1b is switched to communicate with a raw water discharge passage 1c and an inlet passage 1d. The cartridge 5 is detachably attached to the body 1. The cartridge 5 has a water flow port 5a and a water flow outlet 5b on the bottom surface.
It has This water flow port 5a is communicated with the inlet passage 1d of the body 1, and the water flow outlet 5b is communicated with the purified water outlet passage 1e of the body 1. A hollow fiber membrane case 9 housing a hollow fiber membrane 6 is housed in the cartridge 5, and granular coconut shell activated carbon 7 is housed around the hollow fiber membrane case 9. Perforated plates 10 and 11 are arranged to form upper and lower end surfaces of activated carbon 7. A check valve 8 is arranged between the activated carbon 7 and the water flow volume 5a. The check valve 8 has a water flow rate of 5a due to its own weight.
When water pressure is applied, it floats upward and water reaches the activated carbon 7 through the gaps around it. The upper ends of the hollow fiber membrane 6 and the activated carbon 7 almost coincide with each other, and are communicated with each other via the upper space 5c. Therefore, the upper end of the hollow fiber membrane 6 is on the water inlet side. A transparent cap 5d is attached to the earthen wall of the cartridge 5. This cap 5d has a concave shape. The hollow fiber membrane 6 is formed by bending its upper end. Press the cartridge 5 against the body 1 side.
A cover 12 is detachably attached to the body 1.
