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 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.

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).
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.
How much radiation does UV light produce?
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. For typical UV system, approximately 95 percent of the radiation passes through a quartz glass sleeve and into the untreated water.
Why is UV light important for disinfection?
UV Dosage. UV dosage is the most critical function of UV disinfection, because the extent of inactivation is proportional to the dose applied to the water. As individual UV lamps emit a set amount of ultraviolet energy, it is important that a system be sized correctly.

Ultrafiltration Costs. Ultrafiltration uses a membrane-style system similar to reverse osmosis to provide extremely filtered water. The water is pushed through the membrane under pressure, until most contaminants, solids, minerals, and other particulates have been filtered out.
What is reverse osmosis water?
Reverse osmosis is one of the most popular types of water purification. It is also one of the strongest, with the ability to remove a wide range of contaminants from water, including dissolved solids, heavy metals, bacteria, waterborne cysts, and some dissolved particulates. This system improves the taste of water the most out of any other and offers some of the best purification. During reverse osmosis, the water is forced through a membrane under pressure. The clean water is stored inside a pressurized tank for drinking later, while the contaminated water and what is left behind on the filter are washed away and disposed of.
What do you need to know before installing a water filter?
Before installing a filter system, you need to know what is in your water that you want to remove.
