Many neighborhoods have pure water vending machines installed, which is essentially a slightly larger than the home water purifier reverse osmosis membrane water purifier plus a set of billing system, after the reverse osmosis membrane out of the water is pure water, there are relevant staff to sell the water card and a small bucket, the user in the purchase of a card to pay the money, and then use the water vending machine through the credit card system to get water.
Generally speaking, the company that installed the vending machine will test the water quality and replace the filter cartridge regularly, and will provide relevant operating instructions on the vending machine. If the water quality is not too assured, you can buy a TDS water quality detector, the market price is just ten yuan a, you can carry out the test of total dissolved solids in water, if the measured value is a single-digit number or a dozen or less, that is pure water, if the value of more than a few dozen, that the reverse osmosis membrane is not working properly, you need to replace the core.
Relative to the household reverse osmosis water purifier, water vending machine by professionals to carry out regular after-sales maintenance, to solve the household water purifier to buy a machine and find people to replace the cartridge, out of order to find someone to repair the trouble.
The reverse osmosis membrane water purification system will produce wastewater, if the wastewater produced by the vending machine is connected to the water system for use, it is very complete; but if it is directly when the sewage discharge, it is a bit of a waste, after all, water resources are very valuable, you say right?
Reliable or not, depends on the installation of these water purifiers business, can not change the filter in a timely manner. These large water purifiers and household water purifiers, water purification principle is the same, the tap water through the pp cotton, activated carbon, ro membrane and other cartridges, layer by layer to filter out impurities in the water, to achieve the effect of water purification.
The cost of replacing the cartridge is still relatively high, my water purifier just a few days ago to consult the after-sales service, the five cartridges all replaced, the need for 750 dollars, commercial is undoubtedly more expensive. These large water purifiers installed in the community, due to water consumption is relatively large, to ensure that the water quality standards, you need to replace the filter more frequently, then the maintenance cost will be higher. So many businesses in order to save costs, and will not replace the filter on time. These water purifiers are generally not specialized management, there is no government departments to regulate the water quality standard or not, the drinker can not tell, so can not change in time to change the cartridge, or even change the cartridge, it all depends on the conscience of these businesses!
If it is a newly installed water purifier, or can be used, if installed for a long time, and the machine looks very worn, poor health, usually do not see people to maintain, or use it with caution.
In fact, the municipal tap water boiling, fully able to meet the drinking standards, water purifier purified water, long-term drinking on the human body has no benefit, or a little controversial. If you want to drink safe pure water, it is best to install a water purifier in your own home, compared to the water in the barrel and the neighborhood water purifier to play the water, a lot better.
This is actually a management problem and business accountability.
This kind of water purification equipment in the neighborhood, if you can follow the rules of regular replacement of the equipment filter media, there is no doubt that drinking such water must be safer than tap water.
On the contrary, if like some neighborhoods this kind of water purification equipment since the installation, no one cared about, maintenance, replacement. I think drinking such water is undoubtedly a health hazard.
"Huize world said" thank you friends read, look forward to leaving valuable comments!
Automatic water purifier is through the different levels of absorption filtration of raw water "purification", so that the purified water, although less impurities, but calcium and magnesium and other minerals will be the same content is very low, and some are even close to pure water, such water is not suitable for long-term drinking. Otherwise, there will be a lack of calcium, magnesium phenomenon
In addition to the old equipment, water quality is difficult to distinguish, the state of health is worrying
Automatic water purification vending machine "in a long-term exposed state, the outlet is no one clean, I feel that the installation of their own home home is more reliable, at least to control the replacement of filter cartridges, but also according to the situation of the water purifier itself cleaning and disinfection
The water purifier itself, the water purification machine, the water purification machine is a good idea. The water purifier itself for cleaning and disinfection
Not reliable, we installed the machine in the district after the sale of cards less than a year after the people disappeared, the machine is no one in charge.
Unreliable, the real name to tell you, Cangzhou Haixing City Garden District has this situation, I used 100 yuan in cash to buy 120 yuan water card, less than a year after the end of the use of 200 yuan to buy 260 yuan water card, the results of less than 3 months, the machine can not be used, the beginning of the machine owner will call and say, "in the maintenance, is buying parts, accessories on the way! And so explain", time in the passage of time, and then call on the phone is not available, the cell phone number changed, the property is not in contact with not to manage. The reality is that if the lawsuit can definitely win, but who will go to the trouble for a few hundred dollars, I hope you do not fall for it again, or have a good insurance method.
We can buy a bucket of 7.5 liters of drinking water in our neighborhood, which is cheaper than the barrels of water sold on the market. In this regard, the owners of the neighborhood have both praise and opposition.
According to the property, said the machine has a separate water and electricity meters, and then also through promotional activities to attract owners to do card consumption. "Do card recharge 150 yuan in cash to send 20 yuan, so it is equivalent to only need to spend 1 yuan, you can buy a bucket of 7.5 liters (equivalent to 7.5 kilograms) of straight drinking water, if the owners of their own coin consumption, it will cost about 3 yuan to fill a bucket of 7.5 liters of straight drinking water. Many neighborhoods near my home have this kind of drinking machine, its shape is similar, like a vertical refrigerator, about 2 meters high, coin-operated or swipe the card and then press the water button, there will be water flow. These direct drinking machine manual labeled water production process, showing that the drinking water are filtered by multiple programs. For example, the raw water (tap water) after 5 micron PPF fiber, granular activated carbon, compressed activated carbon, precision 1 micron PPF fiber, after the activated carbon, bactericidal purification devices, such as seven treatment procedures, and finally become a direct drinking water on sale.
The young people in the district are more likely to accept this direct drinking water, feel that the water quality is cleaner and safer. Some of the older owners are worried about the quality of the water straight drinking machine is not guaranteed, before the merchants in the community to engage in promotional activities, some of the elderly also fight with the promoters, do not allow them to set up stalls in the neighborhood sales. Although the direct drinking business promotion has been used to direct drinking machine water and ordinary tap water test comparison, so I believe that the water quality of the direct drinking machine will not be different now. But I don't know whether the filter cartridges of the direct drinking machines are replaced regularly.
Past to today, those who eat well water, river water, rainwater precipitation after the water people, there is no prosecution certification, the normal life of a good, instead of eating tap water, drinking water and the so-called direct drinking water is not normal, it is necessary to reflect on why out of so many various names, the problem is where
I have worked in this kind of plant, assembly workers and after-sales service wherever you understand this kind of water purifier. Water purifier almost never drink this water, if you know exactly the source of water, otherwise it is simply not filtered clean, drinking water or recommended to boil and then drink!
Pure water is also filtered by the cartridge, depending on where to play the pure water, pure water needs to use PP cotton, activated carbon, ultrafiltration membranes and RO membranes to filter, the need for electricity, if the pure water is played through these filters, it is reliable, if the cartridge is not enough less than RO membranes can be drunk, then it is mineral water, do not use electricity, if you use activated carbon filtration, then the water will be outlawed to consider, it can only be Tap water, so unreliable from these aspects to analyze it
