Drinking pure water should not be a luxury; it is a basic necessity. In recent times, the most advanced water purification technologies include ultraviolet (UV) purifiers, ultrafiltration (UF) purifiers, and reverse osmosis (RO) purifiers. Each has its benefits and downsides. But do you know the differences between these three? How well can they work individually, and how well do they work together? Let’s find out more about them in this article!
Key Points of Difference between the three: RO, UV & UF
- While RO and UV water purifiers required electricity to operate, UF water purifiers do not. This is also the reason RO and UV purifiers are costlier than UF purifiers and also consume more energy.
- RO and UF technologies remove all bacteria and viruses (and any other microbes) from water, whereas UV purifiers kill microbes, leaving their dead bodies inside the water. It has to be combined with a filtering technology to extract the water free of dead microbial bodies after it has been purified.
- RO water purifiers require electricity to boost the pressure of tap water. UV and UF water purifiers, on the other hand, work under the normal pressure of tap water.
- RO water purifiers can remove dissolved salts from water. This is the only kind of water purifier that can remove dissolved salts. UV and UF varieties, unfortunately, cannot remove dissolved salts from water.
- RO water purifiers below 10000 have a pre-filtration system that makes them possible to work with dirty water. UF purifiers can work with turbid water as well. But UV purifiers need clear water to work.
Reverse Osmosis (RO) vs. Ultraviolet (UV) Water Purifiers:
RO technology removes germs, microorganisms, and certain harmful pathogens, but they cannot remove all kinds of disease-causing organisms. UV purifiers kill pathogens that can cause typhoid diarrhea or dysentery. But the dead bodies of the germs remain inside the water. The biggest con of RO purifiers is that it wastes two-thirds of the water that it processes. UV purifiers do not waste any water.
Reverse Osmosis (RO) vs. Ultra Filtration Water Purifiers:
Ultrafiltration purifiers have membranes with larger pores compared to those of RO purifiers. They can easily handle viruses, bacteria, and other germs, but fail to eliminate TDS. Unlike RO, UF purifiers are low maintenance and are not as expensive. They also do not use electricity to operate. They differ from UV purifiers in the aspect that they do not use ultraviolet radiation for the removal of impurities.
No matter how advanced, each of these water purification technologies Ham one downside or the other. None of them is completely flawless. Hence, a combination of the three technologies RO, UV, and UF, is used along with TDS controllers. TDS stands for total dissolved solids. For the perfect water purifier in your home, make sure that your water purifier has a combination of these three technologies. Hope this article was helpful to you!
