Embodiment
[0284] Next, refer to Figure 9 , an example of the activated carbon 56 as the molded activated carbon described in the second embodiment will be described.
[0285] Figure 9 , showing the graphs of the first example, the second example, the first comparative example and the second comparative example of the shaped activated carbon when the vertical axis is the removal rate (%) and the horizontal axis is the water flow rate (L). The respective conditions of the first example, the second example, the first comparative example, and the second comparative example are shown in the table below. In addition, the removal rate refers to the value obtained by obtaining the chlorine content on the inlet side of the water purification box 4 and the chlorine content on the outlet side of the water purification box 4, and multiplying (inlet side-exit side) / inlet side×100(%) . In addition, the amount of passing water refers to an integrated value of the amount of water passing through s...
no. 1 Embodiment
[0288] In the first embodiment, the ratio (%) of fibrous activated carbon: granular activated carbon: binder is set to 90:5:5 respectively, and the density after filling (hereinafter referred to simply as packing density) is set to 0.22g / ml, at this time, the water flow rate from the start of water flow until the removal rate, which is the normal exchange target, drops to 80% is 800 (L). In the case of general household use, this is equivalent to the amount of water that can be used for about 2.5 months.
[0289] Next, in the 2nd embodiment, the proportioning (%) of fibrous activated carbon: granular activated carbon: binding agent is set to 95:0:5 respectively, and the packing density is set to 0.20g / ml. The amount of water passing until the removal rate of the normal exchange target falls to 80% is 800 (L). Similar to the first embodiment, this is equivalent to the amount of water that can be used for about 2.5 months in the case of general household use.
no. 3 Embodiment
[0300] In the 3rd embodiment, the proportioning (mass %) of powdered activated carbon: binder is set to 99:1 respectively, and the average particle diameter of activated carbon is set to 100 μ m. The amount of water passed until the removal rate of derivative methane (THM) (in other words, the adsorption rate) is as low as 80% is 800 (L). In the case of general household use, this is equivalent to the amount of water that can be used for about 2.5 months.
[0301] Next, in the 4th embodiment, the proportioning (mass %) of powdered activated carbon: binder is set to 98:2 respectively, and the average particle diameter of activated carbon is set to 60 μ m. The amount of water passed until the removal rate of the derived methane of the exchange target was as low as 80% was 850 (L). In the case of general household use, this is equivalent to the amount of water that can be used for about 2.5 months.
