The self-service water purifier in the community, is this water reliable?

0 1 The water from the automatic water vending machine in the community is not a project of national economy and people's livelihood, so the water quality safety should be treated with caution.

The author's drinking habit is to buy bottled water directly as drinking water. Recently, because the bottled water merchants can't send it out, I began to consider direct drinking water in the community. Is direct drinking water really healthy and safe? With the convenience of work, the author decided to conduct a comprehensive comparative test of five water sources: self-service water vending machine water, tap water, water purifier water, mineral water and pure water.

Drinking fountains in residential areas are mostly contracted by individuals, not national livelihood projects.

First of all, talk about the self-service water dispenser in the community. Many residents think that this is a national livelihood project, but it is not. This kind of self-service drinking water equipment is basically contracted by individuals, so whether it can meet the standard of pure water depends on the purification ability of the machine itself and the maintenance level of the equipment by the contractor in the later period.

It seems that these self-service drinking water equipment in my community have been used for a long time, and the bottom has begun to rust. As for maintenance, can the equipment still purify water? Ask a question first!

The water purification principle of domestic drinking fountains is similar to that of domestic water purifiers.

There are 10 items on the self-service drinking fountain in the community, but there may be only five kinds of filter elements and purification equipment involved (according to the analysis of the purification process marked by the equipment), probably PP filter element, compressed activated carbon filter element, RO reverse osmosis filter element, resin filter element and UV ultraviolet lamp. The principle is no different from that of domestic RO water purifier.

There is nothing special about the filtering device of the community water vending machine.

The above picture shows the internal structure of the self-service water selling equipment that was dismantled in a community on the network. You can see that there are several filter elements built in, which are much larger than the household water purifier. Judging from the color of the filter element (clean PP filter element is white), it should have been used for a long time (it has reached the scrapping standard from the color point of view), while the filter element of household water purifier generally needs to be used for half a year to one year before the color of PP filter element can reach the color shown in the above picture.

Therefore, the self-service water vending machine in the community is the same as the household water purifier (large household water purifier), which is the * * * water purifier in the popular words now. They are worn products and need regular maintenance and replacement. If it is observed that no one has changed the filter element of the automatic water vending machine for a long time, please don't pick up the water. The water quality may not be as clean as tap water.

Provide weekly water quality test report of automatic water vending machine.

The water quality test report is attached to the automatic water vending machine, and the test items include PH value, conductivity, turbidity and total dissolved solids, and the time for replacing the filter element is marked. Of course, I didn't see the words of any national organization from the test report, so the test report should be the result of independent testing by the contractor and not authoritative.

Five tests have proved that the water quality of the automatic water vending machine in my community is acceptable.
