Over 100 years ago, German scientists discovered that the top of the water in a lake was sterile by exposure to sunlight. Research led to the discovery of ultraviolet light. Ultraviolet (UV) light in the electromagnetic spectrum is located between X-rays and visible light. Ultraviolet (UV) light has many beneficial properties. UV light is divided into four main categories, UV-A, UV-B, UV-C and vacuum UV. The UV-C spectrum (200-280 nm) is the most lethal wavelength range for micro-organisms. This range, with 254 nanometers as the highest germicidal wavelength, is known as the germicidal spectrum.
UV-C light can cause permanent damage to a wide range of harmful microorganisms in the water. Certain kinds of micro-organisms have or develop an adaptive immunity to conventional disinfection techniques, such as chlorine.
Each type of microorganism requires a specific exposure to UV-C radiation to be destroyed successfully. The targeted micro-organism and should be long enough to be directly exposed to the UV-C radiation to penetrate. The radiation through the cell wall However, it takes only a few seconds of UV-C light rays to inactivate the microorganisms through their
to break the cell wall and disrupt the DNA. This destroys the organism is often complete, that will reduce the ability to reproduce. At least prejudice
• Can significantly reduce the concentration of chlorine and other chemicals
• UV is effective against all micro-organisms (including the very dangerous Cryptosporidium parvum and Giardia lamblia which are not treated by chlorine)
• Greatly improved water quality and a more pleasant swimming environment
• No red eye and skin irritation
• No problems for people with asthma or allergies
• Crystal clear water and clean air,
• Breaks down chloramines and other organic substances into
• Less use of other chemicals for water treatment
• There is no chemical byproducts from the UV system
• Fully automatic, no risk of overdose
• Lower cost of chemicals, electricity and maintenance
• UV is a harmless green technology
