Advantages of UV Purification

Nov. 03, 2021

UV water purification is the most effective way to disinfect bacteria in water. Ultraviolet (UV) rays penetrate harmful pathogens in the water in your home and destroy disease-causing microorganisms by attacking their genetic core (DNA). This is very effective in eliminating their ability to reproduce. Disinfecting water with UV light is simple, effective and environmentally friendly. UV systems can destroy 99.99% of harmful microorganisms without adding chemicals or changing the taste or smell of the water. UV water purification is often used in conjunction with other forms of filtration, such as reverse osmosis systems or carbon block filters.


UV is a natural process and does not produce harmful chemicals in the water. It simply needs to be connected and plugged in at the inlet. It is a safe, effective and environmentally friendly method of disinfection and is widely used in residential and industrial applications around the world.


UV Purification > Chemical Disinfectants

UV systems are an effective means of disinfecting water at the entrance to a home and help to disinfect the entire home. UV systems are strongly recommended for homeowners who may suspect the presence of E. coli, Cryptosporidium, Giardia or any other type of bacteria and viruses in their water. Other methods of killing bacteria or viruses in the water are the addition of chemical disinfectants. 

However, the use of chlorine or other chemicals to disinfect water, as is done by private well owners, is not recommended as they can produce toxic by-products. It is important to avoid drinking any water that may be contaminated with bacteria to protect yourself from any waterborne bacterial diseases.

Advantages of UV purification

No chemicals: UV purification does not use any chemicals such as chlorine or leave any harmful by-products.

Tasteless and odourless: UV light does not impart any chemical taste or odour to the water.

Extremely effective: one of the most effective ways to kill disease-causing microorganisms by destroying 99.99%.

Requires very little energy: uses about the same amount of energy as running a 60 watt light bulb.

Low maintenance: set and forget the type of system, only the UV bulb needs to be replaced annually.


How does UV water disinfection work?

In theory, UV disinfection is a simple process. The 254nm energy from the UV lamp is needed to reach the target microorganisms in the water supply. However, many obstacles can affect the performance of UV light. These barriers include


Suspended matter, including visible and non-visible particulate matter (turbidity);Limescale, fouling caused by physical scale deposits of iron, manganese or calcium carbonate that cover the quartz sleeve.


UV-absorbing compounds, where UV absorption in water is almost entirely caused by dissolved substances. Certain organic substances, such as humic or fumaric acid (tannic acid), and certain inorganic substances, such as iron and manganese, absorb UV light. These contaminants must be addressed for UV treatment to be effective.


Choosing the right UV unit size

If you take your water from a private water supply, it is recommended that your entire home is treated. To ensure maximum satisfaction, choose a UV system of the right size (gpm) to match the peak demand flow in your household. If all outlets are open at the same time, this is only a measure of the amount of water that can flow through the mains.
