Ultraviolet (UV) disinfection and chlorination are both effective methods for disinfecting water. However, there are several benefits of UV disinfection over chlorination. Here are some of the advantages of UV disinfection:
1. Chemical-free disinfection: UV disinfection does not require the use of chemicals like chlorine. This means that there are no harmful disinfection by-products produced during the process. Chlorination, on the other hand, can potentially form disinfection by-products, such as trihalomethanes (THMs), which may have adverse health effects.
2. Effective against a wide range of microorganisms: UV disinfection is effective against a broad spectrum of microorganisms, including bacteria, viruses, and protozoa. It inactivates these microorganisms by damaging their DNA, preventing them from reproducing and causing infections. Chlorine is also effective against many microorganisms, but some pathogens may be more resistant to its disinfecting effects.
3. Rapid disinfection: UV disinfection provides almost instantaneous disinfection. As soon as the water passes through the UV light, the microorganisms are inactivated. Chlorination, on the other hand, may require contact time for the chlorine to effectively kill the microorganisms. This means that UV disinfection can provide immediate protection against harmful pathogens.
4. No residual taste or odor: UV disinfection does not alter the taste, color, or odor of the water. Chlorination, on the other hand, can leave a residual taste and odor in the water, which some people may find unpleasant.
5. Environmentally friendly: UV disinfection is considered environmentally friendly since it does not introduce any chemicals into the water or produce harmful by-products. It does not contribute to the formation of disinfection by-products in the water supply or the release of chlorine into the environment.
6. Low maintenance: UV disinfection systems require minimal maintenance compared to chlorination systems. UV lamps need periodic replacement, but there are no chemical storage or handling requirements associated with UV disinfection.
While UV disinfection has many advantages, it is important to note that it is primarily used for point-of-use or point-of-entry water treatment, such as in residential homes or small-scale systems. Chlorination, on the other hand, has a long history of use in large-scale water treatment facilities and is effective in providing residual disinfection throughout the distribution system. The choice between UV disinfection and chlorination is one that a homeowner on municipal system or a well can decided for him or herself. Chlorine can be removed and Ultraviolet disinfection can be installed. Call us to day for details and be on your way to a healthier life.
