What is Ultraviolet (UV)?

Ultraviolet light is electromagnetic radiation with a wavelength shorter than that of visible light.  The spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the color violet (purple).
 
UV light is typically found as part of the radiation received by the Earth from the Sun. Most humans are aware of the effects of UV through the painful condition of sunburn.

Ultraviolet germicidal irradiation has been studied since the 1930’s and has been used to destroy the microbes that cause indoor air and water pollution. For many years, the medical industry has used UV light to sanitize rooms and equipment. The Centers for Disease Control recommend UV lamps for their germicidal effect.
 
UV can be separated into various ranges, with short range UV (UV-C) considered "germicidal UV." At certain wavelengths UV is mutagenic to bacteria, viruses and other micro-organisms.  Ultraviolet light is part of the light spectrum, with UV-C from 100 nanometers (nm) - 280 nm; UV-B from 280 nm - 315 nm; and UV-A from 315 nm - 400 nm.  Optimum UV germicidal action occurs around 260 nm.

 

How Does UV Disinfection Work?

UV-C light deactivates the DNA of bacteria, viruses and other pathogens, which destroys their ability to multiply and cause disease. As UV light penetrates through the cell wall and cytoplasmic membrane, it causes a molecular rearrangement of the microorganism's DNA, which prevents it from reproducing.  Specifically, UV-C light causes damage to the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA. The formation of such bonds prevent the DNA from being unzipped for replication, and the organism is unable to reproduce. In fact, when the organism tries to replicate, it dies.

 

Common Microorganisms Destroyed by UV Light:

• Bacillus anthracis
• Corynebacterium diphtheriae
• Dysentary bacilli (diarrhea)
• Escherichia coli (diarrhea)
• Legionella pneumophilia
• Mycobacterium tuberculosis
• Pseudomonas aeruginosa
• Salmonella (food poisoning)
• Salmonella paratyphi (enteric fever)
• Salmonella typhosa (typhoid fever)
• Shigella dysentariae (dysentery)
• Shigella flexneri (dysentery)
• Staphylococcus epidermidis
• Streptococcus faecaelis
• Vibro commo (cholera)
• Bacteriophage (E. Coli)
• Hepatitis
• Influenza
• Poliovirus (poliomyelitis)
• Baker's yeast

 

What are the Advantages of UV Disinfection?

• Environmentally friendly, no dangerous chemicals to handle or store, no problems of overdosing.  
• Universally accepted disinfection system for potable and non-potable water systems.  
• Low initial capital cost as well as reduced operating expenses when compared with similar technologies such as ozone, chlorine, etc.  
• Immediate treatment process, no need for holding tanks, long retention times, etc.  
• Extremely economical, hundreds of gallons may be treated for each penny of operating cost.  
• Low power consumption.  
• No chemicals added to the water supply - no by-products (i.e. chlorine + organics = trihalomethanes).   
• Safe to use.  
• No removal of beneficial minerals.  
• No change in taste, odor, pH or conductivity nor the general chemistry of the water.  
• Automatic operation without special attention or measurement, operator friendly.  
• Simplicity and ease of maintenance, TWT Deposit Control System prevents scale formation of quartz sleeve, annual lamp replacement, no moving parts to wear out.  
• No handling of toxic chemicals, no need for specialized storage requirements, no OHSA requirements.  
• Easy installation, only two water connections and a power connection.  
• More effective against viruses than chlorine.  
• Compatible with all other water processes (i.e., RO, filtration, ion exchange, etc.).

Since natural germicidal UV from the sun is screened out by the earth's atmosphere, we must look to alternative means of producing UV light. This is accomplished through the conversion of electrical energy in a low pressure mercury vapor "hard glass" quartz lamp. Electrons flow through the ionized mercury vapor between the electrodes of the lamp, which then creates UV light.

Suspended solids or particulate matter can cause a shielding problem in which a microbe may pass through the UV filter without actually having any direct UV penetration. Iron/Manganese will cause staining on the quartz sleeve that houses the UV bulb, at levels as low as 0.3 PPM of iron and 0.05 PPM of manganese. UV filters are best used AFTER adequate sediment, turbidity, iron, and manganese filtration.   See our Whole House Water Filter here
