Three fifths of the daily water intake for office workers comes from drinking directly from the office, which plays a crucial role in human health. Therefore, office workers need to pay attention to water quality when drinking water. So what are the drawbacks of the common drinking water dispenser and bottled water in the office?

Once bottled water is loaded onto the water dispenser, bacteria in the air enter the sealed bucket with the air, and during the process of draining, air is constantly replenished, which can also cause a large number of microorganisms in the qualified bottled water to multiply, leading to pollution of the water body and water dispenser.

Disease control experts conducted follow-up tests on bottled water: 5 days after opening, the hygiene condition of bottled water sharply declined, with a pass rate of only 20% on the 7th day. By the 10th day, all tested bottled water had exceeded the total bacterial count. So, what are the drawbacks of bottled water?

1. Secondary pollution of bottled water is inevitable

Experts say that the common "secondary pollution" in bottled water is unavoidable. Water delivery is always done by hiring bicycles or tricycles, and the entire process is highly susceptible to "secondary pollution" due to factors such as time, climate, environment, and personnel quality. Bottled water still commonly suffers from the problem of "thousand roll water". When bottled water is repeatedly heated in a water dispenser, it forms "thousand roll water", which appears clean but is actually a concentrated solution of harmful substances such as heavy metals and arsenides.

2. Exceeding the service period, the water bucket becomes a breeding ground for bacteria

According to industry insiders, according to regulations, each water bucket must be scrapped after 100 repeated uses. Experts say that scrapped barrels are often a "paradise" for bacterial growth. Some small and medium-sized bottled water manufacturers do not carefully disinfect the recycled empty buckets, and only rinse them with tap water before use, resulting in a large number of bacteria breeding in the buckets. With this type of bottled water, even the best water will definitely be contaminated. The "black bucket" has not completely exited the market, and the phenomenon of water buckets exceeding their service life is serious. The waste buckets that should have been eliminated are still being used in large quantities, which causes great pollution to bottled water.

3. Black hearted water, black hearted bucket: harmful to health with infinite toxicity

Black hearted water "refers to bottled water directly filled by illegal vendors with tap water. The high molecular weight polymers in the industrial waste of" black hearted buckets "will seep out in the water environment, which is an organic pollutant that can easily cause cancer in the human body. People who drink water from a 'black hearted bucket' will not immediately feel it, but rather, like chronic poisoning, the harm will only manifest years later. Long term consumption of these inferior bottled water can also harm the human digestive and nervous systems, leading to dizziness, stomach pain, and even cancer.

4. The issue of "stagnant water"

The shelf life of bottled water should not exceed 2 days, as drinking aged water can affect health. It is understood that the aging rate of water is very fast. Water molecules have a long chain like structure. If water is not frequently subjected to strong impacts, this chain like structure continues to expand and extend, becoming aged water, commonly known as "stagnant water". There are few personnel in the office, and it takes 7 to 10 days to use a bucket of water. This' stagnant water 'poses a great threat to health! In recent years, the incidence rate of esophageal cancer and gastric cancer is increasing in many areas. Experts believe that it is related to the "stagnant water" that has been stored for a long time.

5. Bacterial contamination of the water dispenser prevents the water from boiling

The special electric structure of the water dispenser makes it very susceptible to bacterial contamination. Firstly, the heating temperature of the water dispenser is 86 degrees Celsius and the cooling temperature is 5 degrees Celsius, which cannot kill bacteria at all. Instead, it is very suitable for bacterial reproduction. Over time, bacteria form a biofilm, which is difficult to remove, forming a bacterial stronghold. After passing through such a water dispenser, clean water carries thousands of bacteria. The water dispenser has a heating temperature of 86 degrees and cannot be boiled, making it unsuitable for brewing tea.

6. High cost

If a company or institution uses bottled water and has 100 employees, the average annual water consumption is about 10000 yuan, which is a considerable expense. It varies depending on the specific situation of each unit.

7. Not convenient

During peak water usage periods, users often make phone calls three or five times but are unable to deliver water to their doorstep. They spend long periods of time waiting for water dispensers to drink. The after-sales service is not up to par. Some manufacturers stop supplying water after customers order it, and users hold water tickets without water to drink.

As the drawbacks of bottled water are exposed, people are beginning to seek more suitable and healthy ways of drinking water, and office drinking methods are constantly changing.

Water is the source of human life, and the purification of direct drinking water removes harmful impurities from the water quality, fully ensuring the cleanliness, peace of mind, and deliciousness of drinking water. The source of direct drinking water comes from tap water, which is ready to drink and convenient for health.
