do you want to continue to buy the water it still? (hen after)

* Still it continues to buy the water even with this? As for the person who is not viewed yet, please view from front volume.

The gold town filter plant which makes the water of the downtown

It continues to buy the water still even now? So, it followed to the first volume, it went to the observation of the filter plant in order to verify the degree of safety of the tap water.

As for this time visiting, there is the Tokyo Katsushika Ku, the “gold town filter plant”
If you mentioned the gold town filter plant, it was about like pronoun of the filter plant which makes the “unpalatable water” before the generation.As for the main criminal that Tokyo water is unpalatable, the extent that, the water is unpalatable in around 47 of high growth period, it was the gold town filter plant, you say that you could move aside the complaint that mainly, it is musty.

Technology of the clean water being immature of course there is that that time, but by the fact that processing of the sewage is insufficient, the blue-green algae propagating in the rivers, the raw water is terribly polluted, the vicious circle that occurred also the clean water becomes bad.As for the especially gold town filter plant in order most to be located to the estuary, as for the soiling of the raw water you say that they were suitable ones.

The such an ill repute high filter plant is born changes now completely and, it is to be designed in such a way that the safe water is made tastily in the extent which produces the water with the brand, “Tokyo water”.

that make the water purification plant in tokyo11there are places, asaka them second only to2making the amount of water is often in the second kanamachijosuijo. amount of water purification is1the sun25mabout the pool3,000cups. mainly tokyo23the downtown district that covers the water.

much of the water in tokyo, it will be a thing of the tama river water system to that of the tone river system, kanamachijosuijo tone river system will have to intake water from the edogawa. if you compare the raw water, the water quality is not good because of the tone river system better than the tama river water system, advanced water treatment facilities have been introduced to make better-tasting safe water.

tokyo water purification has evolved so next page

mechanism of the water purification plant

uptake water from the intake tower, the soil and sand is precipitated in a pond called settling basin. further to remove the turbidity from the supernatant portion of this, inject a coagulating agent. coagulant poly-aluminum chloride is used here (PAC) it is called, material closer to say the most familiar and alum. the course is safe to human body, will be tied to a big chunk smaller turbidity substance is injected in this process, and is not intended that the water itself because tokedashi to be removed all at high speed sedimentation pond.

after thus precipitate the turbidity, will continue to advanced water treatment portion supernatant. in advanced water treatment facilities are, oxidative decomposition of the material from which the cause of the odor substances and trihalomethane contact of water with ozone.

to decompose and remove pollutants through activated carbon layer in the pond biological activated carbon adsorption and then.

this advanced water treatment facilities, heisei city agency for the first time in tokyo4which was introduced in the year kanamachijosuijo, about65%advanced processing, processing is usually35%has been processed at a rate of. kanamachijosuijo is currently in the first3construction of advanced water treatment facilities of the period have been carried out, 2after year100%water will become advanced treatment.

strange as it was also before, tap water, but has established stringent national safety standards, water purification facilities in tokyo is that it provided a safety standard goes further on to the national standard. tap water is so far it has evolved.

tasting the water purification

in the tour was actually made in kanamachijosuijo, i was allowed to be tasting the fresh water. this water from the same thing with water as tap water will flow normally, as noted in the first part, chlorine has been added. than that of water going to each home through a water pipe as it were, would say is chlorine concentration is too dark. is, looking at emergency drinking….

even if taste chlorine taste and smell and i do not feel seem. that it should also, large amount of chlorine without the need for water purification in water treatment facilities have a high degree, i do not have added that only a minimal amount permitted by law. drinking this water, really tap water is bad or chlorine smell i think people would really do.

please try to make sure to drink tap water taste

we dare, after introducing a state of kanamachijosuijo of downtown would be ringleader of water seems to have been bad, and tokyo, honestly i was surprised that the water purification technology has been developed only this.

different water treatment plant land also differences, i think different method of water purification come. in any case desuga, now has become a beautiful river and raw water due to improved technology of sewage treatment, has become dramatically better technology of water purification.

in the same way as old, from prejudice tap water is bad chlorine smell those who are considered the, please try to drink water from the faucet as it is normally at a time. surely kke so delicious? you will be able to review and tap water.
