Ultraviolet Water Filters

Ultraviolet water filters/purifiers are the latest water filters offering efficient water treatment. They provide clean and pure water by removing all living organisms and other contaminants.

Ultraviolet water purification is an unique and rapid technique to remove a number of microorganisms, like bacteria, virus, algae, mold, etc without the use of heat or any chemicals. It is an effective method of water disinfection for many applications because nothing is added to the water. In addition to excellent disinfection performance, it is a simple, inexpensive process and requires low maintenance. It is more reliable than other methods of water filtration.

Working of Ultraviolet Filters
Ultraviolet water filters purify water by ultraviolet purification, which is a proven technology. It is capable of removing microorganisms, such as bacteria, viruses, algae, and fungi, causing waterborne diseases. When water is passed through the UV chamber, it is treated with concentrated amounts of UV light energy, effectively killing all microbes.

Role of Ultraviolet Light in Water Purification
Ultraviolet light is part of the light spectrum. It is classified into three wavelength ranges: UV-C, from 100 nanometers (nm) to 280 nm; UV-B, from 280 nm to 315 nm; and UV-A, from 315 nm to 400 nm. In all these three, UV-C is responsible for water purification, that's why also known as germicidal ultraviolet. It deactivates the DNA of pathogens, like bacteria, viruses, etc and destroys their ability to grow and cause diseases.

By forming covalent bonds between certain adjacent bases in the DNA, it make damages to the microorganisms. Formation of such bonds restricts the DNA from being unzipped for replication, and so they are unable to reproduce.

Applications of Ultraviolet Filters
The ultraviolet filters/ purifiers cover a wide range of applications as they provide the most efficient water treatment and disinfectant process.

• Bottling Manufacture: They are very usable in water bottling industry, breweries, wineries, soft drink, etc as they insures bacteria free water for various purposes.
  
  
• Pharmaceutical and Cosmetic Industries: In these industries, the bacteria free water is a must as it insures abidance with strict water treatment standards, which is essential for product quality control.
  
  
• Hospitals: The ultra-pure water is required in hospitals and pathology labs for kidney dialysis and post disinfection rinses. The ultraviolet filters provide bacteria free water, which is essential for various types of tests.
  
  
• Food Industries: In food industry pure water is required as an additive to several products. The ultraviolet filters insures bacteria free water.
  
  
• Wastewater Treatment Plants: They offer an excellent post water treatment of secondary effluent, which help reducing bacterial concentrations to safe levels without adding any toxicant.
  
  
• Nurseries: Root rot infection is a common problem in nursery trees and plants, which is caused by diseased water supply. Bacteria free water helps minimizing the losses.
  
  
• Swimming Pools: Helps control bacteria, algae and slime formation. Ultraviolet water purification system helps to reduce the amount of chlorine substantially.
  
  
• Laboratories: Ultraviolet purifiers provide ultra-pure water, which ensures accurate testing and research .
  
  
• Farms and Ranches: Ultraviolet filters provide hygienic water, mainly free from bacteria, which is good for animal drinking. It helps increase the production by eliminating losses due to water-borne infection.
  
  
• Electronics Industry: Insures bacteria free water for use in conjunction with de-ionized and high purity water systems.
  
  
• Aquariums and Hatcheries: The ultraviolet filters have become essential in aquariums and hatcheries. They provide bacteria free water, which prevents disease organisms from spreading or growing without producing any by-products toxic to marine life.

Advantages of Ultraviolet Filtration
Ultraviolet filtration technology is a non-chemical approach to disinfection of water. Neither any chemicals nor any other thing is added in this process thus making it simple and inexpensive. It requires very low maintenance. They use germicidal lamps, which are designed to produce a calculated dosage of ultraviolet (generally at least 16,000 micro-watt seconds per square centimeter).

• The UV filtration is highly effective on wide range of pathogens, like E.coli, Giardia, Cryptosporidium, etc.
• This filtration technology can be easily installed within existing water treatment facilities.
• During the filtration process no harmful disinfection by-products are formed.
• It is effective as a stand-alone or as a part of a multi-barrier treatment strategy.
• No awful taste or odor is added to water during the filtration.
• Inactivation independent of pH and temperature.
• It require less installation and operating costs.
• There are no hazardous risks for operators.
• No chemicals are used.
• Very simple to operate.
