Ultraviolet Water Purification (UV)
What are the beneficial uses of germicidal ultraviolet?
Ultraviolet technology is a non-chemical approach to the disinfection of water, air, and surfaces. In this method of disinfection, nothing is added, which makes this process simple, inexpensive, and requires little maintenance. How does this work? Ultraviolet systems use UV light to produce purified water for the entire house. Without adding or taking anything away from water, UV disinfection is cost-effective and environmentally-friendly. It can remove up to 99.99% of harmful waterborne microorganisms.
What microorganisms are deactivated by germicidal ultraviolet light?
As water passes through a UV water treatment system, living organisms in water are exposed to UV light, which attacks the genetic code of the microorganism and rearranges the DNA /RNA, eliminating the microorganism’s ability to function and reproduce, critical for healthcare industries. If a microorganism can no longer reproduce, it cannot replicate; therefore, it cannot infect other organisms with which it has contact. This process of exposing water to UV light is simple but effective. It can destroy up to 99.99% of harmful microorganisms without adding any chemicals to the water. Here’s a list below:
Viruses
Cysts
Salmonella
E. Coli
Typhoid Fever
Polio
Cholera
Infectious Hepatitis
Bacteria
Coliform
How do ultraviolet purifiers work?
Watershield UV Water Purification systems use unique lamps that emit UV light of a particular wavelength that has the ability, based on their length, to disrupt the DNA of micro-organisms. These purifier units contain one or more germicidal ultraviolet lamps. Germicidal Lamps are shortwave, low-pressure tubes that produce ultraviolet wavelengths lethal to micro-organisms killing at 254 nanometers (nm). Water or air that passes through the chamber is exposed to the germicidal UV light, and the genetic material of the micro-organism is deactivated, which prevents them from reproduction and rendering them harmless.
What is germicidal ultraviolet?
UV-C light is germicidal – i.e., it deactivates the DNA of bacteria, viruses, and other pathogens and thus destroys their ability to multiply and cause disease. This short-wave ultraviolet light disrupts DNA base pairing causing the formation of pyrimidine dimers and leads to the inactivation of bacteria, viruses, and protozoa. It can also be used to produce ozone for water disinfection.
How do I size a water purifier?
Proper sizing of water treatment equipment is critical for effective water treatment. In some cases, such as ultraviolet water disinfection, under-sizing a system or not planning for peak flows can result in untreated water passing through the system and contaminating the water already in the pipes and equipment. Our water purifiers are based on the peak flow rate. To give you a reference point, most single-family dwellings use 8-12 gallons per minute.
