UV systems are highly recommended to homeowners who may suspect any E.coli, cryptosporidium, giardia or any other types of bacteria and viruses in the water.
Can chlorine be used to disinfect water?
However, it is not advised to use chlorine or other chemicals to disinfect water like private well owners, because of the toxic byproductsthey create.
Does UV light work?
UV light does not work to eliminate contaminants such as chlorine, heavy metals and VOC’s (Volatile Organic Compounds). UV systems are often paired with Reverse Osmosis Systems to provide a complete purification process for the safest drinking water. Choosing the Right UV Unit Size.
Is UV light harmful to water?
22.5. UV light is a natural process and does not produce harmful chemicals in water. Simply connect at point of entry and plugin in the electricity. It’s a safe, effective and environmentally friendly disinfection method that is widely used for residential and industrial applications around the world.
What is the effective UV dose?
The effective UV dose, expressed in mJ/cm² (millijoules per square centimeter), refers to the necessary UV energy that the micro-organisms (bacteria, viruses, algae in suspension…) must absorb before being destroyed. When this UV dose is reached, the UV-C rays penetrate the micro-organisms’ DNA and eradicate 99,9% of them.#N#The UV dose is a result of an equation between:#N#• the flow rate#N#• the UV exposure time (depending on the device’s design)#N#• the UV-C power emitted by the lamp#N#Other parameters must to be taking into account while calculating the UV dose and notably, the UV transmittance measured as a percentage. It is the UV rays ease to go through water; the easier they are going through, the higher the percentage is.#N#Thanks to our expertise, we are able to offer optimum UV disinfection solutions even with low UV transmittance.

How does UV radiation affect microorganisms?
UV radiation affects microorganisms by altering the DNA in the cells and impeding reproduction. UV treatment does not remove organisms from the water, it merely inactivates them. The effectiveness of this process is related to exposure time and lamp intensity as well as general water quality parameters.
Does UV disinfection change the chemical composition of water?
Furthermore, the UV disinfection does not alter the physicochemical composition of the water. Which means that water going through the UV reactor goes out with the same physical and chemical composition than it has before going in. The process only disinfects by removing viruses, bacteria, microbes, etc.
What is BIO-UV?
There is a wide range of applications for the water disinfection using the UV technology, BIO-UV Group offers solutions for both professionals and individuals. For instance, you can treat surface water, residual water, pool water, industrial process water, drinking water, etc….
What is UV disinfection?
UV disinfection is used in air and water purification, sewage treatment, protection of food and beverages, and many other disinfection and sterilization applications. A major advantage of UV treatment is that it is considered safer and more reliable for disinfection of water than chemical alternatives, while the level of disinfection is much higher.
What are the three types of UV radiation?
UV Types Comparison. Principles of UV Disinfection . UV radiation has three wavelength zones: UV-A, UV-B, and UV-C, and it is this last region, the shortwave UV-C, that has germicidal properties for disinfection. A low-pressure mercury arc lamp resembling a fluorescent lamp produces the UV light in the range of 254 manometers (nm).
What is the radiation range of a UV lamp?
There are UV lamps that produce radiation in the range of 185 nm that are effective on microorganisms and will also reduce the total organic carbon (TOC) content of the water.
Overview
Today, everyone is careful in almost everything. Most especially on what we drink and eat. And the most basic of all is our drinking water. It has to be clean and safe for us and for our family.
What is UV Water Treatment?
Ultraviolet (UV) Water Treatment is a disinfection technology that cleans water by killing many microorganism species by exposing water to high UV light dosage.
How does UV light eliminate the cause of infection and diseases?
Microorganisms exposed to the UV light absorb it, which then destroys the organisms’ nucleic acids, DNA and RNA, both responsible for reproduction and replication. Since these microorganisms cannot reproduce, the risk of infection or disease is thus eliminated.
When was Ultraviolet Light first used in water disinfection?
Since 1916, United States has been using UV Light for water disinfection. It was later on in the 1980s to the 1990s that small-scale UV light water treatment was developed for use in many homes, small and medium scale businesses, and private water supply users.
10 Reasons Why You Need a UV Water Treatment System
UV light kills and eliminates several disease-causing microorganisms and contaminants in the water.
Disadvantages in UV Light Water Treatment
UV light disinfects by only eliminating the microorganisms present in the water. It cannot remove metals, chlorine, salts, oil or other impurities. UV light will work best if paired with other filtration methods to make sure all impurities are removed.
Why would I use UV water treatment over other methods? (using UV instead of Chlorine)
UV light water treatment and Chlorine are both approved by EPA and FDA. But these are some points that you might consider in comparing these two systems:
1 How Do UV Water Filters Work?
The UV water disinfection process utilizes special UV lamps that emit UV light of a particular wavelength. These UV light waves have the ability, based on their length, to disrupt the DNA of microorganisms.
2 Advantages of UV Water Filtration
Municipal water suppliers perform the necessary operations to meet water quality standards, but UV purification systems take water treatment to a higher level—providing a safe solution against chlorine-resistant microorganisms such as Giardia and Cryptosporidium which cause thousands of documented health cases each year.
Disadvantages of UV Water Filtration?
While there are many advantages of UV water disinfection, yet some attention must be paid to the challenges it poses.
5 What are the parts of a UV System?
There are a variety of ultraviolet water purification system makes and models, but most of them have the same basic components. Here is a list of the nine most common components on UV disinfection systems:
What is UV disinfection?
Ultra Violet (UV) light disinfection is one water treatment system that can be used to remove most forms of microbiological contamination from water.
What is the purpose of water treatment?
The Department of Health recommends that all naturally sourced water should be professionally tested and treated before it is used for drinking, bathing, filling swimming and paddling pools, food preparation or cooking. A number of water treatment systems can be used to remove microbiological contaminants that may cause illness.
What happens if water is not filtered?
Water that is not filtered can contain iron, manganese and other particles that can either absorb or scatter UV light reducing the effectiveness of the disinfection system. Microorganisms that are able to pass through protected by shadows created by dirt, debris or other microorganisms may be able to survive treatment.
What is a pre filter?
is equipped with a pre-filter to remove any iron, manganese and other dirt and debri that can either absorb or scatter UV light. has a built in light sensor that can monitor the UV intensity, connected to an alarm system to alert the user in case of low UV level.
