[Popular Science Article] Direct Drinking Water Options for Campuses

11 Feb.,2025

How to germicidal direct drinking water on campus? It is best that you should choose the UVC LED germicidal method.

 

What can you do to protect your kids' straight water health?
We look at three areas:
Water source sterilization treatment options
Usually the municipal tap water treatment is chlorine disinfection sterilization The advantage of this treatment is to save money, can maximize the water resources to disinfect and sterilize. But it is easy to leave a bad smell, in the long pipeline transportation may cause secondary pollution.
In addition, there are several water sterilization methods on the market:

1 ozone sterilization. Sterilization of low power, start time is long, easy to leak in the process of transportation or use, and its harm to the human body is easy to cause cancer. Ozone has a strong oxidizing properties, can directly destroy the cell wall of bacteria, decomposition of DNA, RNA, proteins and polysaccharides and other macromolecules, so that microorganisms can not normal growth and reproduction, resulting in their death. The effect of good by-products, but can not be in the water long-term residual, and the effect is not persistent.

2 Mercury sterilization. Ultraviolet mercury lamps in the ultraviolet band commonly 254nm, it is the use of low-pressure mercury vapor in the discharge process of ultraviolet radiation, low-pressure mercury vapor mainly produces 254nm and 185nm ultraviolet light, mercury lamps sterilizing effect of the characteristic wavelength is 253.7nm, the radiation power to reach the level of watt (W), which is widely used in the environment of a large area, with a good bactericidal effect. But the traditional ultraviolet mercury lamp germicidal lamp in the sterilization process, once the lamp rupture, mercury will cause serious water pollution, Japan's Minamata disease back then is so caused, to the then people around the world have left a small impression. Interested friends can also go to check. Mercury is a heavy metal substance, commonly known as mercury, mercury can be evaporated at room temperature, mercury vapor and mercury compounds are highly toxic (chronic).

So it has obvious disadvantages:
(1) Bulky shape, large size, and equipped with high voltage electricity;
(2) Start-up time is long, can not do that is open and ready to use;
(3) fragile, short service life, up to 90% of the service life consumed in the frequent switching phase.
3 LED UV sterilization. Is the current stage of the scientific level can achieve no side effects, sterilization effect, sterilization power, the best way to short waiting time.
(1) it has high efficiency sterilization, deep ultraviolet LED issued by the UVC section of the ultraviolet light on the bacterial killing effect is generally within a few seconds, it is through the ultraviolet section of the destruction of bacterial nucleic acid structure, but the traditional water sterilization methods such as the above mentioned sterilization methods, to achieve the efficiency of the deep ultraviolet sterilization generally takes 20 minutes to 1 hour or even longer;; (2) a wide range of bactericidal properties.
(2) Wide range of sterilization. Because bacteria, antigen and other microorganisms are not resistant to ultraviolet light, so the deep ultraviolet light on almost all bacteria and viruses can be killed with high efficiency, and this deep ultraviolet sterilization technology, but also to a certain extent to inhibit the growth of some higher aquatic organisms, such as algae, red worms, grasshoppers, etc.; (3) safe and environmentally friendly, does not contain any harmful substances, but the traditional water sterilization methods such as those mentioned above generally take 20 minutes to hours or even longer.
(3) safe and environmentally friendly, does not contain mercury. Deep ultraviolet LED products relative to the most obvious advantage of mercury ultraviolet germicidal lamps is that its sterilization light source does not contain mercury, there will be no mercury pollution. Traditional UV mercury germicidal lamps in use will be a safety risk, and deep UV LED products are a safe and reliable device, does not contain heavy metals, simple operation, safe and reliable operation.
(4) The product is more energy-saving, long lamp bead service life, low maintenance costs. Deep UV LED power is about one-tenth of the mercury lamp, this ratio greatly saves costs. Through the lamp beads emit UV photons, simple operation.
(5) Small size, flexible design, easy installation. It can be placed into water purification equipment to make it sterilized. Deep UV LED sterilizer, small size, flexible device design, can be applied in the traditional UV mercury lamps can not be applied in the narrow space.
(6) domestic brand Unidux is the exclusive agent of Japan Asahi Kasei, its LED deep ultraviolet sterilization technology has been very mature, the lamp beads raw materials for the U.S. CIS company to provide, life expectancy of up to 12,000 hours, one hour a day, available 32.8 years. Using 265nm band UV sterilization, which is the most efficient value of sterilization.

We need to make improvements in our facilities
Did you know there are faucets with LED UV sterilization?
Did you know that there are faucets with lighted reminders?
Did you know that UV sterilizers can be installed in your water fixtures to add sterilization to the water line?
Did you know how easy it is to use?

As early as 2015, our products were certified by the National Sanitation Foundation (NSF) for five consecutive years
In 2018, we were the first to develop UV germicidal products in China - UV LED lamp beads were exclusively licensed by Asahi Kasei
We have our own laboratory

It is closely related to the health of students' drinking water
We need to try to choose the one with TDS water quality monitoring function.
With cold, hot water, and mixing function of the drinking fountain
We also need to choose the right capacity and power according to the size and demand of the school.
If your home or campus has already installed a large and expensive water dispenser
and do not have uv sterilization function
Don't worry and be anxious
You can contact us
We will create a solution for your existing equipment
See if you can install a LED UVc sterilizer for your equipment.
With the sterilizer adapted to install, optional straight drinking machine equipment type:
Desktop/vertical direct drinking fountains: suitable for school offices, classrooms, corridors, placed on the floor or countertop, easy to move and simple to use.
Wall-mounted direct drinking fountains: suitable for places with limited space, usually installed on the wall to save floor space.
Interconnected straight water dispenser: can be directly connected to the water mains to provide a continuous large amount of water supply, suitable for places with high demand during peak hours.
