Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a water treatment system that can produce so-called delicious water without any unusual odor or taste.

(B) Conventional Technology In recent years, rivers and the like have become polluted at an alarming rate, and tap water taken from these rivers has also become sufficiently contaminated.

Therefore, various water treatments such as sterilizing tap water by adding a large amount of chlorine and filtering it with activated carbon are used to make the tap water drinkable and to a certain extent 'f1. Produces water with reduced odor.

However, in high-rise apartments and condominiums, tap water is first supplied to an elevated water tank installed on the rooftop, etc.
Thereafter, water may be supplied branched to each living space or room. In this case, the sterilizing effect of chlorine may be reduced and bacteria may grow in the elevated water tank.

Therefore, there is a sterilizer that sterilizes tap water using ozone, and the water is sterilized by mixing ozone into the tap water.

(C) Problems to be Solved by the Invention However, such prior art still has the following problems to be solved.

■ Although ozone is mixed with tap water to sterilize tap water, there were cases where ozone remained in the water.

In this case, residual ozone in tap water exceeding a certain value □
If it contains, there is a risk that it will have an adverse effect on the human body, and it is impossible to ensure safety for the human body.

■ Residual ozone in tap water that exceeded a certain level actually made the tap water taste bad, making it undrinkable.

■ As mentioned above, even if tap water is treated, scale or iron ions leached into tap water from pipes etc.
There was a strange occurrence of metal in the tap water.

Although such scale can be easily removed by filtering with activated carbon, ions in tap water cannot be easily removed, and therefore, these ions make tap water taste bad.

An object of the present invention is to provide a water treatment system that can solve the above problems.

(d) Means for Solving the Problems The present invention includes a sterilizer that sterilizes tap water using ozone in a waterway from the upstream side to the downstream side, and a cluster treatment device that activates the tap water. , a water treatment system l characterized in that it is equipped with a mineral addition device that elutes mineral components into tap water, a cooling device that cools the tap water, and a deozonation device that removes residual ozone from the tap water;
This is related to.

The present invention is characterized in that an electrolytic dechlorination/deozonation device is used as the deozonation device.

(E) Functions and Effects Since the water treatment system according to the present invention is equipped with an ozone-based sterilization generator, it can be used even if the sterilizing effect of chlorine is reduced and bacteria are multiplied in an elevated water tank installed in a building, etc. Even if there is, the water can be completely sterilized using a sterilizer before being discharged from a drain, ensuring the safety of drinking water.

In particular, when using an ozone sterilizer, it is possible to: ■ reliably kill bacteria and viruses, ■ effectively decompose odor-causing substances and eliminate strange odors, and ■ remove iron and manganese. It suppresses oxidation and prevents the formation of scale. Furthermore, it can decompose various compounds whose carcinogenicity is considered a problem, such as trihalomethane, and reduce the amount of residue left behind.

In addition, in the present invention, if sterilized ozone remains in tap water, the electrolytic dechlorination/deozonation device
By lowering the amount of chlorine and residual ozone in tap water to safe values, safety for the human body can be ensured, and the taste of tap water can be improved.

Furthermore, the cluster treatment equipment activates water molecules in tap water, hydrates iron ions contained in tap water, increases the degree of freedom of water molecules, and produces delicious water with small groups of water molecules. can do.
