UV disinfection has been used in the medical industry for many years and it is now becoming more popular for disinfecting drinking water, swimming pools, and other recreational areas.

But what are the pros & cons of this type of disinfection?

In this article, we will discuss how UV disinfection works and some of its advantages as well as disadvantages.

The Pros of UV Disinfection

UV disinfection is the process of using a beam of ultraviolet light to kill microorganisms in drinking water and other fluids. It is typically accomplished by the use of high-intensity lamps that emit photons at wavelengths from 200-260 nm with peak efficiency between 257-262 nm.

Here are the pros of using one:

UV Disinfection Is Easy to Use and are Non-Toxic

One thing that makes UV disinfection one of the best is that it is so easy to use. You just need a UV light and that&#;s all you have to do. Anything else like chemical treatment or boiling takes more time, energy, money, and manpower

UV disinfection also does not require chemicals to work which means there are no side effects from the process. It is very safe for humans as well as animals in general because for this reason

If you&#;re constantly on the go with your family then this might be one of those things that can help make life easier for you since they don&#;t take up much space at all either.

You&#;ll surely find it fitting to be able to use UV disinfection in your home if you want a water purification method that is not only safe but also easy.

UV Disinfection Is Adjustable

If you plan to disinfect a wide range of areas, then you&#;ll be satisfied with how easy it is to adjust UV disinfection. You can either have a small appliance that you carry around with you or attach one to your faucet.

And the best part about this type of system is that it has no moving parts, which in turn makes them very reliable and durable for long-term use.

You Can Use UV Disinfection Anywhere

UV disinfection is not only applicable for water but it can also be used on any fluids that need to be sterilized. This includes urine, blood, and other body fluids.

Its use in hospitals has become more popular over the years with its ability to quickly kill bacteria without letting them grow back while being able to touch anything else which might have come into contact with it too long ago

With this in mind, you can clearly see that UV disinfection is one of the most versatile and reliable types out there.

Cons of UV Disinfection

Just like all other disinfection products out there, UV disinfection has its share of cons too and we have highlighted the ones you need to know:

UV Disinfection Must Be Used Frequently

If you want to maintain the effectiveness of UV disinfection in your drinking water, then you need a system that will be used often. It&#;s not really enough if it is just being left on for a few hours because microorganisms can still grow back as long as they have some time

UV lamps also require frequent maintenance and replacements, so this might prove costly over time

It does not do well with high concentrations of minerals either which may clog up the lamp or even cause them to stop working altogether since there are no chemicals involved. This could make it ineffective at times especially when cleaning things like pools

There is always an upfront investment needed if you decide to use UV disinfection!

Disinfection With UV Light Can Be Expensive

UV disinfection is not cheap, as you&#;ll need to invest in lamps and this only gets higher if you plan on using it for more than just your home.

It can get very expensive when used at larger scales too since the amount of UV light required will be much greater which means that there&#;s a chance that electricity costs might go up with this one.

UV Disinfection Takes Time

UV disinfection machines take time to work, which can be a hassle if you&#;re trying to clean something that is already dirty

It does not kill all the microbes in one go and some do get missed so it&#;s best used when combined with other methods.

UV disinfection also needs time for the water to pass through it before the process can be completed, so this might not work well with a sink that is constantly running.

Conclusion

The post discussed the pros and cons of UV disinfection for water purification. This is an important topic so it&#;s worth looking into what you need to know about it.

Understanding Ultraviolet (UV) Light and Its Types

 


UV Light: Unveiling the Invisible Spectrum


UV, short for Ultraviolet, also known as black light or UV light, is a form of electromagnetic radiation that lies just beyond the range of the human eye's perception. With wavelengths ranging between 100 and 400 nm (nanometers), ultraviolet radiation possesses a shorter wavelength than visible light, resulting in a higher energy content. This heightened energy level enables UV to reach the ionization potential of organic molecules and initiate chemical reactions.


Distinguishing the Variants of UV


When considering the impact of ultraviolet light on both living organisms and the environment, it is important to differentiate between three distinct types: UV A, UV B, and UV C. Each type of UV radiation has its unique characteristics:


  1. UV A: Often referred to as "long waves," UV A exhibits a wavelength ranging approximately from 315 to 400 nm.

  2. UV B: Occupying a wavelength between 280 and 315 nm, UV B falls within a shorter range compared to UV A.

  3. UV C: Known as "short-wave radiation," UV C encompasses wavelengths between 100 and 280 nm. UV C is specifically utilized in disinfection and sterilization applications.


Understanding these divisions allows for a comprehensive comprehension of the diverse effects and applications of ultraviolet light.

 

How does UV disinfection work?

UV C disinfection is based on the absorption of UV C radiation by, for example, micro-organisms. With the rapid absorption of the UV-C, the DNA and RNA becomes damaged in the micro-organisms, so that the microorganisms can no longer reproduce. Just like with a normal lamp, the power is expressed in UV lamps in Watts (W). The more Watts the UV lamp has, the more power and effect for disinfection or sterilization this lamp will have.

Benefits of UV disinfection?

  • UV has no addition of chemicals that may affect taste, odor and color or that are there have to be purified again later on.
  • UV is environmentally friendly. In principle, no harmful intermediates arise and only cost energy.
  • UV does not create carcinogenic disinfection by-products
  • UV light has many application areas and is an effective disinfection method.
  • UV light works quick, safe and is easy to use and maintain.
  • Ability to inactivate protozoa like cryptosporidium and giardia.
  • UV light has low energy costs .

Disadvantages of UV disinfection?

  • UV light needs the right amount of energy to be effective.
  • UV light is effective for microorganisms not for chemicals.
  • Photochemical damage caused by UV may be repaired by some organisms.
  • UV light does not delete, but only "breaks".

What can be removed via UV disinfection?

With UV disinfection and sterilization microorganisms, such as bacteria, viruses, fungi and traces on or in all kinds of materials or substances are killed or greatly reduced in number. Pathogenic organisms like cholera, polio, typhoid, hepatitis and other bacteria are also inactivated with great efficacy. The sterilization and disinfection of air and water is mainly done with use of UV light. Ultraviolet light is often combined with peroxide for organic waste and makes organic micro-pollutants harmless.It is more about breaking down than removing with UV light.

UV light for room disinfection

UV-C is very effective in disinfection or sanitizing rooms and spaces by killing viruses and bacteria that are present in that room. If you have UV light with enough Watt, and you have for example the corona-virus exposed to it for multiple seconds, then it can be killed or significantly reduced in number. Various sources say that around 6 seconds of exposure to UV light can kill about 99% of Covid-19 (the amount of watt was not mentioned here). This is one of the reasons that UV is used for disinfection of the air and surfaces in rooms.
