WATER PURIFICATION SYSTEM
This is the process by which undesired chemical compounds, organic and inorganic materials, and biological contaminants are removed from water. The purification procedure reduces the concentration of contaminants such as suspended particles, parasites, bacteria, algae, viruses and fungi.
ULTRAVIOLET WATER PURIFIER
Ultraviolet water purification is the most effective method for disinfecting bacteria from water. Ultraviolet (UV) rays penetrate harmful pathogens in your home`s water and destroy illness-causing micro-organisms by attacking their genetic core (DNA).
UV WATER PURIFIERS VS. WATER FILTERS
Reverse osmosis systems, ultra-filtration systems, carbon filters and ceramic filters all separate contaminants from water through tiny pores of a filter or a membrane. Unlike water filters, a UV water purifier does not remove particles from water. UV treatment purifies water by exposing living organisms to ultraviolet light, the UV purifier then works alongside water filtration systems to provide clean water.
ADVANTAGES OF USING A UV PURIFIER
- Disinfects without chemicals. Ultraviolet wavelength doesn’t leave by-products in water like chemical disinfectants.
- Adds no tastes and odors. UV disinfection does not chemically alter the water in any way, shape or form.
- Easy to maintain. An annual UV lamp change is the most frequent maintenance used.
- No water wasted. The UV treatment process requires no water to the drain.
- Protection during natural disasters. When city water is compromised, a UV system keeps you drinking water safe.
DISADVANTAGES OF USING A WATER PURUFIER
Doesn’t work during a power outage. A UV system requires electric or solar energy to run.
WHEN TO USE A UV PURIFIER?
UV purification is the best option anytime your water contains bacteria or wants additional protection in the case of a natural disaster. By the time your city water plant issues a Boil Water Advisory, the water has already been contaminated. Having a UV system keeps your water free from harmful viruses and pathogens when the water supply is compromised.
If you own a private well or your water is stored in a storage tank, you`ll need a UV water purifier unless you disinfect your water with chemicals. The well owner is responsible for removing bacteria from water and ultraviolet treatment is the most effective way to do it.
A UV water purifier treats micro-biologically unsafe water with germicidal ultraviolet light. The UV wavelength scrambles the DNA of living organisms in the water, so they can no longer reproduce and make you sick. If you drink bacteria-infested water, the organisms can embed in your digestive tract and replicate. Ultraviolet radiation renders bacteria, viruses, parasites and fungi unable to replicate by damaging the nucleic acids of their DNA.
A UV water purifier exposes living organisms such as bacteria, viruses or cysts like (Cryptosporidium and Giardia) to a germicidal ultraviolet wavelength. With enough energy, UV radiation at the 254-nm wavelength disrupts the DNA in pathogenic micro-organisms so they cannot reproduce. The ultraviolet light prevents bacteria from spreading diseases through drinking water.
UV disinfection de-activates living organisms, but it does not remove particles from water, add chemicals or remove bad tastes and odors.
UV disinfection treats water for;
- Dysentery bacilli
- Mycobacterium tuberculosis
- Hepatitis B
- Some virus
Cryptosporidium is a parasite that enters the intestinal tract and causes illness like Montezuma`s revenge. Crypto is resistant to Chlorine used to disinfect city water. UV water purification protects you from pathogenic organisms like cryptosporidium in water.
UV water treatment is safe, it does not use harmful chemicals or alter the composition of water. A UV sterilizer uses UV-C light to disinfect. UV-C light is harmful to humans just as it is for microscopic living organisms. But unless you touch or look at the UV bulb while it’s on, you`re in no danger of exposure.
Chlorine treatment is an alternative to UV, but ultraviolet treatment is much safer. Ultraviolet light treats water for protozoa that chlorine disinfection is unable to remove. A UV system is much easier to maintain and safer to use than chemical disinfectants. Treating water with chlorine requires a retention tank and precise injections and solutions. Many water waste treatment plants now use UV water purification to eliminate harmful chemical by-products in water from chlorine or chloramine treatment.
UV systems sterilize water quickly and effectively. UV disinfection deactivates 99.99% of living organisms in the water. They are designed to run constantly to guarantee the water you use is always safe. Because UV purifier is not a filter, there`s no waste water or debris left behind to clean out. Every drop of water that enters the UV system is purified.
Ultraviolet water purifiers come in a wide variety. The size of UV system you need depends on the flow rate of your water. Sizing according to flow rate allows water to contact the germicidal wavelength long enough to be effective. Like the size, the price of UV systems varies.
