How do I choose the right UV light treatment system?
A UV system is primarily used for removing viruses and bacteria from water. An ultraviolet water disinfection system cannot remove sediment, hardness, iron, lead or chlorine. That's why pre-filters are often installed before a UV system. UV light can only eliminate microorganisms such as viruses and bacteria.

What are the components of UV treatment?
UV treatment systems are relatively simple — which is why they are so compact — and only consist of a few key components: lamps, a stainless steel reactor vessel, sensors, and a power module.
What is UV sensor?
Sensors are vital components for monitoring the effectiveness of the system over time and gauging when maintenance needs to be done. The UV sensor measures the intensity of the lamp output to ensure proper dosing. UVT sensors measure transmittance, which is essentially how effectively UV light is penetrating the solution. If transmittance decreases, it could be an indication of turbid water or lamp fouling. There isn’t much variation in options for these system components other than the vendor.

As hard water can physically stain the quartz sleeve component of a UV, it is recommended that the water hardness be less than 7 gpg. Tannins should be less than 0.1 ppm or 0.1 mg/l. Turbidity should be less than 1 NTU. Iron should be less than 0.3 ppm (0.3 mg/l) and manganese should be less than 0.05 ppm (0.05 mg/l).
Why do tannins stain water?
Tannins colour the water with a yellow hue and can cause staining on fixtures and affect the aesthetic quality of drinks. In relation to UV tannins interfere with the UV's ability to penetrate into the water due to the tannins absorption capabilities.
What is the right UV dose?
The right UV dose can be a difficult question and is directly dependant on the application. Many industrial applications are pathogen specific, meaning equipment and UV dose is chosen based on the dose requirements of a specific pathogen or group of pathogens.
How much UV light does E. coli need?
For the average home owner, the target pathogens typically require low UV dosages to be eradicated. As an example, E.coli, requires a UV dose of 6 mJ/cm² for a 4-log or 99.99% kill. Currently, three different UV dose levels exist in the market; 16, 30 and 40 mJ/cm².
Where is UV disinfection installed?
The UV system is installed on the cold water line in your home . The disinfection occurs by the ultraviolet lamp contained inside the stainless steel reactor chamber. Although the UV energy itself gives off no heat, the low pressure mercury vapour lamp ("light bulb") does emit energy in the form of heat.
What happens when a microbe is exposed to UV light?
In simple terms, when a microbe is directly exposed to the UV light, the DNA (its fundamental building block) of the cell is damaged thus preventing replication. If a cell cannot reproduce, then the cell cannot cause infection.

What is reverse osmosis in water treatment?
Some water treatment systems rely on reverse osmosis, a process in which dissolved inorganic solids (such as salts) are removed from a solution (such as water).
What is hard water?
Hard water has a high level of minerals making it unpleasant to drink or use. Water softeners remove certain minerals, including calcium and magnesium, to soften the water. Water conditioners. The term “water conditioners” applies to a wide variety of products that remove impurities from water.
Why is water treatment important?
Water treatment systems are used to improve the quality of the water in a household, business, restaurant or elsewhere. If a municipality’s water treatment system is not sufficient, or if a consumer is relying on water from a well source, then a home water treatment system becomes a viable option for cleaner, safer water.
Why is it important to maintain a UV water filter?
The most important aspect of maintaining a UV water filter system is changing the lamp regularly. A UV Lamp is the heart of the UV sterilizer system and it needs to be well maintained to ensure the UV system can keep harmful viruses and bacteria out of your water.
What happens when water runs through a UV light?
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 protects the UV lamp. This build up will cloud the sleeve and inhibit the UV light from penetrating the water – allowing microorganisms to pass by without being killed.
How often should I replace a UV lamp?
It is EXTREMELY IMPORTANT to replace the lamp every year on schedule. New lamps will generate a UV light dosage of nearly 60 mJ/cm2. Over a year’s period the UV light dosage will drop to about 30 mJ/cm2-- the minimum dosage needed to effectively kill bacteria. At this point, the UV lamp should be replaced. Almost all UV systems are meant ...

Some of the most important potential contaminants to test for in your well water include coliform bacteria, calcium and magnesium, lead, arsenic, iron, sulfate, nitrates, sediment, fertilizers, pesticides and herbicides, and VOCs. Varying levels of each of these impurities will cause various issues in your homes and require different forms ...
Why isn't my well water filter removing microorganisms?
Most water filters for wells aren’t capable of removing microorganisms because they’re small enough to fit through the filter pores. Ultraviolet light, however, doesn’t filter these pathogens out of water – instead, it damages their DNA, killing them and preventing them from being able to duplicate.
