Reverse Osmosis versus Ultraviolet Technology

Why UV technology out-weighs RO water purification methods

Water is a precious and scarce commodity. The preservation of water and making sure it is clean is this year’s top priority. Therefore, we need to ask the question whether we are using this scarce commodity to its fullest potential. Are we using purification method that is giving us optimal results regarding cleaner water? Do we get the optimal quantity of water once it the water has been purified?

The leading methods in water purification are Reverse Osmosis and UV water purification. Let’s have a look at these two methods, their differences and furthermore why UV technology is the more efficient and viable option.

What is Reverse Osmosis?

Reverse Osmosis is a process in which dissolved inorganic solids (such as salts) are removed from a solution (such as water). This is accomplished by household water pressure pushing the tap water through a semipermeable membrane.

What is UV water purification system?

An ultraviolet water purification system typically consists of a UV light source with an output of around 254 nanometres which produces radiation of a significantly greater intensity than the radiation produced by sunlight.

How does UV water purification differ from RO water purification?

– RO purification produces lots of wastewater. With UV water purification, there is no wastewater generated in the process.
– RO takes more time to purify than UV water purification.
– For a capable RO system, it requires electricity to boost the water pressure whereas, with a UV system, regular tap water pressure would work.

Why UV water purification out-weighs RO water purification?

Both Reverse Osmosis and UV water treatment have their drawbacks, i.e. the need for electricity and the fact that UV cannot remove dissolved water. However, UV water purifications out-weighs reverse osmosis in that it is more affordable to use UV technology and furthermore there is no wastewater when using UV water purification methods.
UV water purification is a very cost-effective way to kill a majority of harmful microbes associated with most common water-borne illnesses. Viruses such as the hepatitis virus, which is known to be highly resistant to chlorine-treated water, are quickly eliminated through UV treatment.

UV water filters do not introduce chemicals in the water. As a result, the taste and colour of the water remain virtually unaltered, and there is also no danger of any harmful by-products resulting from the use of UV filters. Also, UV water purifiers are easy to install, are easy to maintain and do not damage septic tanks or plumbing.
