Abstract

PURPOSE:To improve the taste and offensive smell of tap water to a large extend by using a cartridge for a water purifier obtained by forming fibrous activated carbon and a chelate resin and/or an ion exchange resin using a microfibrilated fiber, a heat-fusible fiber or a heat-fusible resin powder as forming agent. CONSTITUTION:A cartridge for a water purifier is constituted by forming fibrous activated carbon and a chelate resin and/or an ion exchange resin using a microfibrilated fiber, a heat-fusible fiber or a heat-fusible resin powder as a forming agent. That is, since the fibrous activated carbon of the cartridge is excellent in the removing properties of free chlorine or a mold smell, the mold smell of tap water can be removed to an extend impossible to feel and the chelate resin or ion exchange resin is excellent in the adsorptivity of a heavy metal ion in tap water. Further, since the microfibrilated fiber, the heat- fusible fiber or the heat-fusible resin powder is used as a binder, the large contact area with tap water is held and pressure loss is lowered.

DISCLOSURE OF THE INVENTION The inventors of the present invention have studied a method of forming an adsorbent of a water purifier cartridge into a compact shape while maintaining high adsorbability.
As a result, when the fibrous activated carbon is molded with the microfibrillated fiber, the heat-sealing fiber, or the heat-sealing resin powder, a molded body in which the particles or the powder of the chelate resin or the ion-exchange resin are included is tap water. Free chlorine contained in
The inventors have found that the adsorptive and removable properties of mold odor and other odors and heavy metal ions are extremely excellent, and based on this, the present invention was reached.

In order to remove free chlorine and heavy metal ions, it is necessary to pass through a layer filled with a free chlorine removing material and a layer of a chelate resin or an ion exchange resin. As the chelate resin or the ion-exchange resin, a resin filled with particles having a diameter of 1 to 2 mm is often used in order not to increase water resistance. However, since the diffusion speed of ions into the resin is slow, a large amount of resin is required to obtain a sufficient amount of treated water as a water purifier, and therefore it is inevitable that the capacity of the water purifier will be considerably large. . On the other hand, consumers are always looking for a compact water purifier that is easy to handle.

A lot of granular activated carbon has been conventionally used in water purifiers, but its ability to remove free chlorine and mold odor is not sufficient. However, if fibrous activated carbon is used, it is relatively easy to treat tap water to the extent that the odor of these impurities is not felt at all.

The chelate resin and ion exchange resin used in the present invention can be widely used as long as they have metal ion removing properties. Further, particles having a particle diameter of 100 μm or less are preferable, and particles having a particle diameter of 3 μm to 100 μm are more preferable. Ten
Particles of 0 μm or larger have a slow removal rate of heavy metal ions, and are therefore insufficient as an adsorbent for water purifiers. The smaller the particle size is, the faster the adsorption rate of heavy metal ions is, which is generally preferable for water purifiers, but it is difficult to fix fine particles of 3 μm or less between the fibers of the fibrous activated carbon with a binder. Therefore, it is necessary to use a large amount of binder at the time of molding, and the water flow resistance increases, so the demerit that the purified water flow rate decreases cannot be ignored. In addition, the chelate resin or the ion-exchange resin may be used alone or in combination.

In order to remove heavy metal ions, a cation exchange resin is usually used in many cases, but when the cation concentration is high, the pH may shift slightly to the acidic side.
In such a case, it is preferable to use a cation exchange resin and an anion exchange resin in combination, or an amphoteric ion exchange resin may be used.

The molding method is not particularly limited, but the following method is excellent as a method for preparing a uniform molded body. That is, the fibrous activated carbon cut into 3 to 5 mm, the chelate resin or ion-exchange resin powder, and the binder are dispersed in water to form a slurry. A water purifier cartridge is molded by pouring this dispersion into a mold such as a wire mesh, draining water and drying. Alternatively, the cartridge can be prepared by a method in which the slurry is used as a raw material for papermaking, and the obtained paper is wound into concentric circles and molded.

Granular activated carbon has been most often used as a water purifying agent for the purpose of removing these substances, and more recently, water purifying agents having various new components have also been used.
However, it is difficult to remove free chlorine or biochemical substances causing mold odor with granular activated carbon to such an extent that the odor is not felt. As described above, fibrous activated carbon has an extremely high adsorption activity, and the decomposition catalytic property of free chlorine is significantly higher than that of granular activated carbon.Therefore, biochemical substances that cause free chlorine and mold odor are removed from those odors. It is relatively easy to remove it to the point where it is not felt.
