には適しなかった。また、温水では吸着能力がなくなる
ため水中の塩素の除去ができず、冷水では逆に溶けてい
る有用なミネラルまで吸着してしまう欠点があった。Since the conventional water purifier mainly uses the adsorption and filtration action, there is a limit to the water purification capacity, and the standard amount of water that can be purified is 10 liters per day and 180 liters for half a year. , It was not suitable for treating large amounts of water such as baths and showers. In addition, since hot water loses its adsorptive capacity, chlorine in water cannot be removed, and cold water, on the contrary, also adsorbs useful dissolved minerals.

It is an object of the present invention to provide a water purification pellet suitable for removing chlorine from a large amount of water in water purifiers, baths, showers, pools and the like.

Hereinafter, the above problem is solved by a water purification pellet containing 40% or less of Ca 3 (PO 4 ) 2 . The water purification pellets are mixed with the above components, pressed into powder, and dried and sintered at a temperature of 100 ° to 500 ° C, which is lower than the thermal decomposition temperature of each component substance. Depending on the binder, it can be solidified at room temperature.

Calcium phosphate does not perform a chlorine removing reaction, but acts as a buffer against pH abnormality in water and has a function of returning PH to neutrality.

ぼ原水と同じである。Comparing this example with a commercially available activated carbon adsorption type water purifier, there is no difference in the removal rate of free chlorine at a flow rate of 2 l / min, but the concentrations of calcium and magnesium are the same as the commercially available activated carbon adsorption type water purifier. However, in the present embodiment, it is increasing. Further, when the flow rate is increased to 10 l / min, the removal rate of free chlorine is 80% in this embodiment, while it falls to 60% in the commercially available activated carbon adsorption type water purifier. In particular, in the case of warm water of 45 ° C, the reactivity is improved in this example and the removal rate of free chlorine increases to 98% at 4 l / min. However, in a commercially available activated carbon adsorption type water purifier, the adsorption capacity decreases and free chlorine is reduced. The removal rate has dropped to 10%. The concentration of calcium and magnesium is almost the same as that of raw water because the temperature is high and it does not absorb.
