The Disadvantages of the Ultraviolet Water Purifier
By Tony Cunningham

The ultraviolet water purifier is an outstanding water purification system which uses the help of concentrated ultra violet rays to get rid of all the possible impurities and make the water totally safe for drinking. The ultraviolet water purifier works only with the help of electricity; without electric current (though it requires an extremely low amount of energy) there is nothing that this system can do to have water purified.

The Ultraviolet Water Purifier Has a Few Disadvantages

There are many people who believe that the ultraviolet water purifier is the best there can be in water purification. While it is true that the ultraviolet water purifier is an excellent water cleanser, there are a few drawbacks that force people to have viable stand-by alternatives when using the UV purification method.

1. Total dependency on electricity. This type of water purifier needs electricity in order to function properly. That leaves us with the fact that in case there is no electricity, then there is no water purification either. This would, in the long run, be extremely critical to the potability of the water and the dependability of the ultraviolet water purifier.

2. Cannot remove impurities physically. This type of purifier is able to render the water clean by killing and sterilizing the harmful bacteria, germs and all others micro-organisms. It cannot physically “strain” the water to get it free from all the impurities.
The ultraviolet water purifier works by ‘exterminating' the existing micro-organisms – some good along with those which are bad, which is not a great idea. Human beings need the support and intervention of friendly micro-organisms, and destroying them all is not a very good idea.

3. The ultraviolet water purifier is expensive. The use of the UV lights (electricity) for getting the water treated in a large house can actually be quite expensive. Hence, this is a mode of purification mostly used by people who have both, i.e. time and money.

4. Filters are required as back-up. The ultraviolet water purifier becomes less and less efficient as the amount of contaminants increase; this is when the UV lamp cannot function well because of the presence on metals, chlorine and a number of chemicals. In this case, filters are required to keep the water free of contaminant particles so the UV lamp can do its work. This, in turn increases the cost of the water purification.
