UV water treatment system

Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength uv light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. The effectiveness of germicidal UV depends on the length of time a microorganism is exposed to UV, the intensity and wavelength of the UV radiation, the presence of particles that can protect the microorganisms from UV, and a microorganism’s ability to withstand UV during its exposure.

It offers the most cost-effective way of protecting residential drinking water against biological contaminants when compared with the others water systems. Water UV treatment devices can be used for whole house, well water and surface disinfection. Water UV’s disinfection has come a long way since it was first invented.
It’s application to disinfection has been an accepted practice since the mid-20th century. It has been used primarily in medical sanitation and sterile work facilities.

Increasingly it has been employed to sterilize food, air, drinking and wastewater as the holding facilities are enclosed and can be circulated to ensure a higher exposure to the Ultraviolet UV. And although ultraviolet UV is a new idea to some, ultraviolet technology has been used for decades by municipal water suppliers and commercial water bottling plants.

Is this type of filtration safe? While most skin cancers are a result of exposure to UV rays in sunlight, the UV light in water disinfection UV systems do NOT cause cancer. The entire process of exposing the water to the Ultraviolet light takes place in an enclosed container posing no risk to family or pets.

UV disinfection is approved by the EPA and is an environmentally friendly disinfection method as it is a chemical-free process and creates no byproducts.

How Ultraviolet Water Filter Works

Where do you put a UV water filter?

UV system use special lamps that emit Ultraviolet light of a particular wavelength that has the ability, based on their length, to disrupt the DNA of micro-organisms, improving your water quality. These Ultraviolet  light waves are also referred to as the Germicidal Spectrum or Frequency.

  1. The Ultraviolet light source is mounted in front of a flow chamber through which water passes in a fast flow rate.
  2. The water is exposed to the UV lamp as it passes through the chamber.
  3.  Any harmful chemicals and bacteria that are present in the water are rendered sterile by exposure to germicidal radiation.

An ultraviolet water purification system typically consists of a UV lamp  with an output of around 254 nanometers which produces radiation of a significantly greater intensity than the radiation produced by sunlight. The UV light attacks the genetic code of the microorganism and rearranges the DNA /RNA, eliminating the microorganism’s ability to function and reproduce. If a microorganism can no longer reproduce, it cannot replicate, therefore it cannot infect other organisms with which it has contact.

UV radiation is so effective that it can eliminate up to 99.99% of bacteria and viruses, including those associated with water-borne illnesses such as Typhoid, Gastroenteritis, Hepatitis, Flu, and Cholera.

Is UV water filter necessary?

Does UV kill bacteria in water?

Waterborne diseases are conditions caused by pathogenic micro-organisms that are in your water supply. Those diseases can be spread while bathing, washing, drinking water, or by eating food exposed to contaminated water. The most common symptoms are:

  1. Diarrhea and vomiting
  2. Skin, ear, respiratory, or eye problems.

Various forms of waterborne diarrhea disease are the most prominent examples and affect children in developing countries most dramatically.

According to the World Health Organization, waterborne diseases account for an estimated 3.6% of the total DALY (disability-adjusted life year) global burden of disease and cause about 1.5 million human deaths annually.

The World Health Organization estimates that 58% of that burden, or 842,000 deaths per year, is attributable to a lack of safe drinking water supply, sanitation, and hygiene

This process of exposing water to UV bulb is simple but effective, destroying 99.99 percent of harmful microorganisms without adding any chemicals to the water. Concluding you will be getting clean water that is chemical free. It can help decrease the waterborne disease and can keep you safe from:

  • Viruses
  • Bacteria
  • Cysts
  • Coliform
  • Salmonella
  • Giardia
  • E.coli
  • Cryptosporidium
  • Typhoid Fever
  • Flu
  • Polio
  • Dysentery
  • Cholera
  • Meningitis
  • Infectious Hepatitis

Our health must be first in our list of priorities if we don’t have a healthy body all of our life gets harmed.

Does UV kill virus?

The UV purification systems can be used to protect against water-borne viruses, bacteria, molds and pathogenic disease-causing microorganisms such as giardia and cryptosporidium.

Even viruses such as the hepatitis virus, which are known to be highly resistant to chlorine-treated water, can be relatively easily eliminated through UV treatment.

UV water purification can be used to treat water whether it’s from a municipal water supply, a drinking-water well, lake or a spring. Several manufactures sell UV purifiers for residential water treatment purposes. The systems come with varying capabilities and prices and are designed to address a wide variety of residential water treatment needs.

How effective is UV sterilization?

How many does a UV system cost? Does UV lamp remove odor from water? Does it really works?

I bet all of these questions are in your head, to truly understand if UV system is effective, here are some benefits you’re going to get if you choose to give it a try!

  • Once installed, annual service is usually all that is required
  • Reliable – consistently keeping water safe with a great costumer service
  • Lamp & sleeve replaced annually
  • Water flows through the system without need for holding tank
  • Fast flow rate
  • More effective than chlorine or chloramines
  • Conserves water
  • Low energy usage –  Most ultraviolet water treatment systems require only an annual change of lamp.
  • Although the initial cost of some UV applications are a bit more than chlorination, the low operating costs make it pay for itself in no time.

Types of Water Filters: What Do I Need?

There are two steps for you to base your decision.  You can decide the best water filtration method for your home according to:

A) The nature of water filtration that will suit your lifestyle & funds.
If for instance, you want to filter All the household water, then you need a whole house water filter. However, whole-house filters tend to have a higher cost. If cash is short, then a faucet filter would be a good alternative.  Faucet-mounted filters can increase your water quality more economically.
OR
B) The particular contaminants that you are concerned about and want to eliminate. If you are particularly troubled about lead pollution (for instance), then you can pick a filter that concentrates on this problem.

We recommend always going with option B unless events force you contrarily. So, we are going to inform you about contaminants so you can choose a water filter.

Your water is coming out what appears to be clear but in reality it’s not actually “clear” as to what’s in the water coming into your home. And that’s why you need a water treatment system. Americans commonly believe that when we switch on the tap, the water that pours out is safe. Homeowners in Flint, Michigan assumed so up until an examination revealed hazardous degrees of lead in their water.

Similarly, 6 million individuals living in 8 states within the High Levels region were influenced by the outcomes of a study that discovered 2 aquifers included uranium levels considerably greater than the EPA‘s maximum pollutant level.

What exactly are contaminants by definition?

A contaminant is specified by the Safe Alcohol Consumption Water Act (SDWA) as “any kind of physical, chemical, biological, or radiological compound or issue in water.” The EPA says, “Drinking water might reasonably be expected to consist of at least small amounts of some impurities.” It’s a crucial to consider the precise degree of the impurity since according to the EPA, “the presence of impurities does not necessarily suggest that the water positions a wellness risk.”

How does my water supply get contaminated?

The means water becomes polluted depends upon the kind of impurity. Water contaminants like oil are one of the most popular as a result of sea oil spills, yet the pipes in your home can just as quickly be the resource. Due to variables like old pipes, remember that your next-door neighbor’s polluted water does not suggest your water is likewise polluted. Physical pollutants mostly influence the physical appearance or other physical properties of water. Instances of physical contaminants are debris or organic product suspended in the water of lakes, rivers and also streams from soil erosion. These kinds of contaminants are common in city water supply, but as we said before a water filtration system can fix this.

Chemical impurities are components or substances. These contaminants might be naturally happening or man-made. Instances of chemical impurities consist of nitrogen, bleach, salts, pesticides, metals, contaminants produced by microorganisms, and also human or animal medications. Biological impurities are organisms in water. They are likewise described as microbes or microbiological pollutants. Instances of organic or microbial contaminants consist of germs, infections, protozoan, and also bloodsuckers, the UV System can easily get rid of them.

Radiological impurities are chemical aspects with an out of balance number of protons and also neutrons causing unstable atoms that can produce ionizing radiation. Instances of radiological contaminants consist of cesium, plutonium and also uranium. Pollutants like these are typically the result of erosion of natural deposits.

How much does a UV water filter cost?

Water filtration systems come with ranging capabilities and values and are meant to address an extensive variety of household water treatment needs. On average, home UV water purifiers start at just $250 for a moderately small point of use system and top out at around $1400 for a whole house system. The size UV system you need depends on the flow rate of your water. Sizing according to flow rate allows water to contact the germicidal wavelength long enough to be effective. Some models of manufactures in this space include:
You can look for other brands, and most of these merchants sell a variety of systems starting with relatively small point-of-use systems to more substantial, whole-house UV water purifiers.
In general, though, anyone considering a UV water purifier needs to consider certain basics such as the radiation dosage given by a particular model. The system needs to be near to 40,000 nanowatts of UV light. A system’s ultraviolet transmittance capability or the capability of its ultraviolet light to penetrate water is also another important consideration to make.

Does UV light remove odor from water?

The UV disinfection water system itself doesn’t remove odor from water since the odor comes from sulfur and the UV System removes only microorganisms like viruses and bacteria. UV’s systems destroy 99.99% of harmful microorganisms without adding chemicals or changing your water’s taste or odor, as a result, the taste and color of the water remain virtually unaltered. The UV water filter needs to be combined with the other filtration system to remove other chemicals, including the ones that provoke the rotten egg smell.
You can learn more about the odor in the water here.

Which is better UV or RO?

There are so many answers to this question, but essentially it has been proven that RO Purifier System is better than UV when the goal is to filter chemicals and contaminants.

So you can understand it better we are going to give an introduction about Reverse Osmosis (RO) System. The Reverse Osmosis process is a type of filtration that uses a semi-permeable, thin membrane with pores small enough to pass pure water through while rejecting larger molecules such as dissolved salts (ions) and other impurities such as bacteria.
The RO system moves the molecules from a region of higher solute concentration to lower solute concentration by using the pressure of incoming water across the membrane and leaving the impurities behind. Although it may remove bacteria because of the osmosis process, those bacteria that were removed can become attached to the membrane and use it to multiply, that’s the reason why Reverse Osmosis Water Filters are not licensed for the proposal to remove viruses and bacteria.

On the other hand, the UV Water filter kills 99,99% of microorganisms that can live in your water, but it doesn’t filtrate contaminants and chemicals. Concluding, the better filter depends on what is your goal, if you already have good water that comes without contaminants and chemicals directly from your supplier, you should get a UV filter. That way you can get 99,99% free of contaminants water, with a relatively inexpensive filtration, no customer service required, an environmentally friendly system and supply clean water to your whole house water supply.

But if you want water with the best taste and odor, and free of chemicals and contaminants, then Reverse Osmosis is your guy! You should only do a quick research about all the pros and cons of this water filter, it has a very slow rate and wastes a lot of water, besides its high cost. You can read all about it in our Reverse Osmosis Filter page!

How long do UV water filters last?

UV water purifiers can last several years, but the lamp lasts about 9000 hours. UV’s systems are uncomplicated to manage and designed to run continuously, that’s why to last this long they require maintenance like any other water treatment system. While most UV systems share many associations, there are often some differences in keeping a particular system.  Strictly follow the manufacturer’s preservation schedule and instructions to avoid jeopardizing the system.

Replace the UV lamp once a year – It’s very crucial to replace the lamp every year on schedule

A UV Lamp is the heart of the UV treatment system, it uses mercury vapor as fuel to ignite the UV wavelength. The lamp needs to operate properly to ensure water is safe. Unlike regular light bulbs, UV Lamps do not burn out – they solarize, the mercury inside the lamp dissipates. This means that over time they reduce in their light wave intensity to about 60% of what a new UV lamp provides. A UV lamp endures about 9,000 hours or 375 days (if you run it all the time). But after that year of use, it’s the capacity to kill bacteria will gradually decrease.

UV Sleeve Cleaning & Replacement – Change Every Two Years

Water running through a UV system often carries minerals, sediment, and other debris. These contaminants will eventually build up on the UV quartz sleeve that shields the UV lamp. Check the quartz sleeve when you change the lamp to make sure it’s clear. This build-up will cloud the sleeve and inhibit the UV light from entering the water, permitting microorganisms to pass by without being destroyed.

Pre-filtration Monitoring and Periodic Changes

As we said before, UV will not clean your water from chemicals, debris, and minerals. If you choose to use it, you need to be conscious that it’s highly probable that a separate prefilter (and even a water softener) may be demanded in extension to the ultraviolet system. Be alert to correctly maintain any pre filtration systems (such as sediment filters, carbon filters, water softener, and other systems) and regularly confirm they are working as expected. This will involve periodic changing of filters and the addition of chemicals or other solutions, as needed.
