Water Treatment UV Germicidal Equipment Failure Warning! These 4 types of water quality with UV lamps is equal to “breeding hotbeds of bacteria”.

Have you ever wondered if the UV germicidal equipment in your home is really effective? Many people think that with UV lamps installed, the water must be clean, but is this really the case? Today we will talk about those who may step on the mine situation, especially for some special water quality, with UV equipment is not only useless, and will even “reverse” become a paradise for bacteria!

Why can UV sterilization? Is it reliable or not?
First of all, the principle - ultraviolet (UV-C) is a wavelength between 200-280nm light, this light can directly damage the structure of microbial DNA or RNA, so that they “inactive”. Simply put, it is the bacteria and viruses in one net. Theoretically, as long as the UV lamp power is sufficient, the speed of water flow is appropriate, it is indeed an efficient and environmentally friendly sterilization technology.
But here's the thing: not in all cases, UV lamps work as expected! In fact, if the water quality of your home belongs to the following types, then I'm sorry, you may spend money in vain, but also brings the risk of secondary pollution!

The first type: turbid water UV sterilization of the water itself is very high transparency requirements. If your tap water contains sediment, rust or other suspended particles, these impurities will block the ultraviolet light to penetrate into every drop of water. The blocked area becomes a small playground for bacteria to multiply without fear, while you think you are drinking “pure water”. Therefore, it is important to ensure that there is an efficient filtration system in place to remove these particles before use.

The second category: high hardness water (rich in minerals) If you live in the northern region or well water area, the term “hard water” is certainly not strange. High hardness means that calcium and magnesium ions are more, these ions are easy to adhere to the pipe wall and the UV lamp surface to form a layer of “protective film”, seriously weakening the intensity of ultraviolet radiation. At this time, not only can not kill bacteria, but also provide a comfortable environment for microorganisms.
The solution is simple: install a softener or descaling device to reduce the hardness before using the UV lamp. Tip illustration: Showing a UV lamp covered with scale and a small view of the scale layer harboring bacteria under a microscope.

Category 3: Water containing large amounts of organic matter Agricultural irrigation return flows, lake withdrawals, or impounded rainwater that has been stored for a long time can turn otherwise clear and transparent drinking water into an eutrophic state. In this case, even though it has been treated and looks clean, a large amount of dissolved organic carbon (DOC) may still remain in it. When these organics come into contact with strong ultraviolet light, not only will they not be broken down, but they may also generate carcinogenic by-products like trichloromethane! Therefore, once you find out that the original source of intake is of this particular type, choose your disinfection method carefully.

Category 4: Direct use of deep wells/underground springs without pre-treatment Underground springs may look natural, but in reality they are often mixed with hydrogen sulfide, iron ions or other reducing impurities. These components react directly with UV light, wasting much of the energy that would otherwise be used to inactivate microorganisms. At the same time, due to the long-term closure of underground springs, it is also easy to carry anaerobic environment specific microorganisms, such as sulfate-reducing bacteria, which is not ordinary UV lamps can be completely dealt with Oh. It is recommended to use a multi-stage filtration program to enhance both safety and taste.

How to better utilize the UV equipment?
In order to make the UV equipment at home really play the role of “health guardian”, we need to pay attention to the following points:
-Regular replacement of consumables: for example, the quartz casing on the dirt must be cleaned in a timely manner, otherwise even the most expensive equipment can not function properly.
Match the pre-filter: Make sure that most of the suspended particles and impurities have been filtered out before entering the sterilization process.
-Reasonable control of the flow rate and power matching: too fast flow will lead to part of the area exposure time is not enough, while the power is not enough directly lead to the inactivation effect is weakened.
-Choose professional brands and products with good after-sales service guarantee: don't buy cottage goods casually because the actual use of the effect gap is huge!
Written here, I believe we have understood, although the ultraviolet sterilization sounds very scientific and environmentally friendly, but the specific circumstances to be specifically analyzed. If the water conditions at home do not meet the requirements, and then the senior expensive equipment is just for show. And truly healthy and safe, we need to each link on a more thoughtful and cautious.
