RO Purifier : Difference between RO and UV

For safe drinking water, there are multiple purifiers available in the market although the two most popular water purifiers options in India happen to be Reverse Osmosis (RO) and Ultraviolet (UV) technique-based purifiers. Most consumers are either unaware of the options available or find it difficult to make a distinction between two purification methods. This is the reason people end up buying the wrong water purifiers.

In this article, we will provide you with information that helps you in selecting the most appropriate purifiers.

What is RO and How does it work?

Reverse Osmosis RO water purification process involves the filtration of water through a semipermeable membrane. RO purifiers are best for water with high TDS content. So if you are staying in an area where the water supply contains a high amount of TDS, it is recommended to buy the RO water purifier for safe drinking water.

The disadvantage of having a RO water purifier: While there are no major drawbacks of an RO purifier, a reverse osmosis system, however, is not as effective in killing microorganisms.

Ultraviolet Water Purifier

UV purifiers have a chamber containing a UV lamp, and when the water passes off through this chamber, UV light does its job in deactivating harmful contaminants.

However, UV purifiers are not effective in lowering the TDS value. If your water supply is of low TDS and is contaminated with microbe only, it is recommended to go for a UV water purifier.

A UV purifier is not effective for water with high TDS content.

Cost variations

UV purifiers are largely inexpensive as the major function of the UV is only to kill microorganisms present in water with low TDS value while the RO purifier due to its multi-scale performance is expensive.

Energy Efficiency and Time To Purify

Almost every electrical appliance comes with an energy-saving feature. Due to the several-stage filtration process, RO purifiers require more energy when compared to UV purifiers. Time matters, even for purifiers, due to the difference in the purification process, UV filters cleanse water in much less time than RO purifiers.

Water wastage

UV purifiers do not require additional water for the purification process, hence zero water wastage. RO filters need additional water for the purification process, and this drained-out water is undrinkable due to the high TDS levels but can be stored with a tank for domestic purposes. Thus wastage of water can be saved with RO if stored properly.

The only way to decide on the correct water purifier for you is to get a LAB test for your water.

Different types of water purification methods

Waterborne diseases cause thousands of fatalities in India every year. While the government provides us with clean water for our daily needs, it is not suitable for drinking purposes. One needs to adopt water purification methods or RO to consume water without fear of diseases, chemicals, odors or noxious elements.

Simple methods such as where one uses a sieve at the valve are not sufficient to filter out clean drinking water.

Boiling water is cost-effective as compared to buying and installing water filters. Boiling water at a high temperature removes bacteria, virus and chemical additions from the water. However, dead micro-organisms and impurities settle at the bottom of the water. To remove these impurities, one must strain the water through a microporous sieve.

As boiling water is a labor and time-intensive process, there is a need to install a water filtration system in the house.

Many filters look similar but have different characteristics. Therefore, it is important to understand the differences to select a water filter most suitable for your needs:

  • There are significant differences in the filtration quality of the water depending on various types and brands of filters available.
  • NSF certification does not guarantee or imply the elimination of any particular contaminant.
  • Some filters use multiple technologies to eradicate contaminants, while others may use a single type of technology.

This blog’s purpose is to introduce the most common types of water filtration processes as detailed below:

RO
  1. Distillation

Distillation involves evaporating water by boiling it to extremely high temperatures. The water vapor that arises from this method is condensed back into filtered, liquid water.

Distillation removes minerals, bacteria, and chemicals that have a high boiling point. However, as the water boils at 100°C (212 °F), this method doesn’t remove the impurities that have a different heating point. Volatile organic chemicals such as herbicides, pesticides, and many more may not be filtered via this process.

  1. Reverse osmosis (RO)

Reverse osmosis filters water through a semi-permeable membrane in order to stop larger impurities and more harmful molecules from entering. The membrane acts as an exceptional filter as the process involves pushing the impure water against its natural direction, which requires more energy. Therefore, the process needs power-driven pumps to function.

Reverse Osmosis can only block molecules that are bigger than water. It is suitable for removing chemical pollutants such as chloride, chromium, copper, sodium and lead. Reverse osmosis systems eliminate more contaminants than carbon, making them a prevalent choice for many consumers. However,  ROsystems do not eradicate dissolved gases like hydrogen sulfide, few insecticides, and herbicides. Carbon filters combined with RO purifier gives better result in cleaning impurities.

  1. Activated Carbon Filter

Activated carbon filtration is great at removing contaminants like chlorine-based compounds, few pesticides and industrial elements. Galvanized carbon used in this process is an absorbent form of carbon, based on charcoal. This process is normally used in many home water filtration systems. Carbon eliminates impurities by chemically bonding to the water that is discharged into the system. It includes using the active absorption aptitudes of carbon in reducing contaminations and also eliminates bad odors and tastes. It is significant to note that carbon filters do not have the ability to eliminate inorganic pollutants such as nitrates, fluoride, sodium and arsenic.

  1. Ion Exchange

Technology works to soften water by using a resin to replace detrimental ions with ones that are less damaging. Ion exchange is frequently used to soften water since it has the ability to exchange calcium and magnesium with sodium. In this process, the ion-exchange filter efficiently splits apart the composites around it.

There is still a need to go through an additional filtration to be able to consume this water. In order for this purification system to work for a prolonged period of time, the resin must be often “invigorated” with harmless replacement ions.

  1. Activated Alumina Water Filter

Activated alumina targets fluoride in drinking water. The filter is built of aluminum oxide (Al2O3), a similar element to sapphire and ruby without any of the coloring impurities. Activated alumina removes fluoride, arsenic, thallium and selenium from drinking water. With several pores on its surface, the alumina can condense up to 99% of fluoride absorptions in the normal fluoridated water.

It is important to acknowledge and understand that a good water filtration system is the first line of defense when it comes to your daily water requirements. Maintenance and service of RO on regular basis is mandotary for healthy drinking water.

How often should you get your RO serviced?

Reverse Osmosis, commonly known as RO is the most common water filtration technique used in Indian households, But, what is RO and what does an RO water purifier actually do?

RO helps remove impurities from unfiltered water. It is a special kind of filtration technology, in which, water is deionized by pushing it under the pressure using a semi-permeable, absorbent membrane. This process sieves large molecules or contagion. The water then moves from the more concerted side (more impurities) to less concerted side (less impurities) to offer uncontaminated and clean drinking water. The clean water processed is known as permeate and the left over water is known as brine or litter. Given the pivotal role that the RO filters and membranes play in the process, timely replacement of RO filters and membranes is vital. To optimize the efficiency of your RO unit, regular servicing is essential.

Why it is essential to change your filters and cartridges?

A filter is like the lungs of your water purifier, filtering detrimental waste product from your drinking water and ensuring only the cleanest and safest water makes its way to you. With regular use, wreckages or fragments can clog the inside of the filter which can damage the filer (or even the RO) permanently. Also, given the filters are carbon-based, they lose their absorbent properties with time and hence need regular replacement. That’s why it is important to maintain to pay close attention to RO and replace your RO filter on time.

How often should RO filters be replaced and serviced?

The pre-filter RO, which is mounted outside the RO water purifier, should be changed within 3 to 4 months, but it depends on the quality and volume of water distilled. The other pre-filters such as, DI cartridge, Carbon and Sediment filter can ideally be replaced within 6 to 12 months, subject to how many gallons of water passes through them, but every filter should be inspected independently. Therefore, to be sure and safe, it is mandatory to get your RO filters changed within 1 year. Whereas, RO membrane should be replaced every 2 years. If RO service is not performed on a regular basis, this could result in pollutants being present in your drinking water, which can be hazardous for health.

While the above acts as a helpful guide, the actual time and frequency of servicing are completely dependent on the amount of water being filtered from your RO, the impurities in your supply tap water, and the service cycle. The bottom line is if you have been using your filter for almost a year now, it is probably time you get it serviced and filters, etc., replaced.
