Best Water Purifier – Buying Guide
What is the indicator of life on any planet?
When we say, we are exploring possibilities of life on Mars, what is it that astronomers and scientists are searching for? The answer to both the questions is ‘Water’.
Yes, water is as essential to life as air. One cannot imagine any life form without water. Fortunately, our Earth is blessed with sufficient water to take care of life in the present as well as the future generations.
Having said that, are we ensuring that the future generation has access to clean and pure water to drink?
The answer to this question is a NO as well as a YES. NO, because the release of human and industrial waste is the primary cause of water pollution in the world.
Different sources of water
Sources of water pollution
The rivers are pristine when they descend from the melting snow caps. As they find their way to the plains, these rivers gather salts and minerals from the rocks and sand.
All these impurities find their way into the human settlements thereby causing water-borne diseases like cholera, dysentery, etc. Therefore, there is an urgent need to purify the water resources before consuming them.
This is the concept behind the functioning of the various water purifiers. You have different methods of purification based on the level of impurities and TDS in water. We shall discuss each type of filter for the benefit of all.
Types of impurities in drinking water
As discussed earlier, you have various kinds of natural salts finding their way into your kitchen through the water resources. Similarly, groundwater also contains a lot of minerals and salts in its natural form.
Eliminating these wastes requires the use of modern technology like Reverse Osmosis (RO), Ultraviolet purification (UV), and Ultra-filtration methods (UF). The modern water purifiers employ any or all of these methods of purification.
The acceptable TDS levels
We have seen the concept of TDS in water. We know how it manages to find its way into the water resources. In a way, our body needs some of these minerals and salts for its healthy growth.
Hence, one should ensure not to eliminate them completely from the drinking water. Now, the question arises as to what the acceptable TDS levels are.
Note that these levels are purely indicative. In the normal course, you will find ground level as well as other water sources having TDS levels below 900.
As per the above table, it should be fair for consumption directly. Is it true? Unfortunately, the answer is NO. The level of concentration of individual elements of TDS is more important than the general TDS value.
It can happen that you might have water with TDS levels in the range of 300. But, the water can have a high concentration of arsenic or mercury and a lower concentration of other salts.
Under such circumstances, is the water safe? You have the answer at the tip of your tongue. This water is certainly not palatable. Hence, you need water purifiers to eliminate these impurities completely.
Water purification technology explained in brief
This is a universally popular method.
You are also able to eliminate TDS up to 90% using this process. The RO water filters work on a 5 or 6-stage purification depending on the configuration of the water purifier.
The sediment filter
This is an optional arrangement. Usually, you have this filter fitted outside the machine. This filter takes care of the visible suspended particles and larger impurities. This filter enhances the life of the RO membrane as it eliminates the larger particles and does not allow them to enter the machine.
You need not use this sediment filter when the input source of water is clear, especially the water treated by the municipalities before distribution to the households.
Pre-activated carbon filters
The pre-activated carbon filter removes organic and the other volatile compounds from the water that usually give the water its bad odour.
Reverse Osmosis mechanism
The next stage of filtration is the RO filtration. In the normal course, the water does not have a tendency to move from a higher concentration to lower concentration when passing through a semipermeable membrane.
Hence, you need to use a pump to push the water through the RO membrane. This is the principle of reverse osmosis. The RO membrane removes all kinds of impurities in the water such as TDS, pesticide residue, heavy metal impurities like mercury, lead, arsenic, and biological impurities like bacteria, viruses, and microorganisms.
This water is separated into two parts, the impure part that goes down the drain and the pure and filtered water that passes through the UV chamber for the next stage of filtration.
The pure water obtained through RO filtration contains traces of bacteria and viruses. This is because the RO membrane cannot filter out impurities with molecular weight less than 20. It cannot eliminate monovalent ions like sodium, etc. Hence, this water now passes through the UV chamber where the ultraviolet radiation kills all microorganisms and bacteria thereby making the water 100% safe to drink.
The resultant water now passes through an Ultrafiltration membrane to remove traces of residual impurities. This filtration membrane contains minute pores that trap any impurities that might have escaped elimination in the RO process.
The Post-activated Carbon filter
This filter is responsible for removing the volatile organic compounds that cause the bad odour of the pure water flowing out of the RO water purifier. This improves the taste of water.
The TDS Controller
The water that comes out of the RO water purifier is pure and healthy. But, the RO mechanism eliminates almost all the TDS from the water. In fact, it removes more than 90% of TDS from the input source. This includes the good and healthy salts like calcium and magnesium, etc. These salts and minerals are necessary for the overall growth of the body.
The TDS controller solves this issue by separating the input water into two parts, A and B. Part A goes through the RO membrane whereas Part B passes through the UV / UF membrane that does not remove the TDS but kills the microorganisms.
The TDS controller then selectively mixes this water with the RO purified water thereby increasing the TDS levels and increasing the pH value of the water.
The disadvantage of the TDS controller is that it releases a part of the input water into the RO purified water thereby providing an opportunity for contaminating the RO purified water.
The mineralizer releases the appropriate minerals lost during the RO purification process alone. This replenishes the mineral content of the water and thus improves the quality of output water.
Which filter to buy?
You have seen the functions of different types of water filters, but the principal question remains unanswered. Which type of filter is best suited for your home? This depends on the quality of water you have as the water source.
Let us now look at the various sources of water and see the normal kinds of impurities associated with the particular source. This will enable you to decide which water purifier to choose.
|TDS Levels||Is the water muddy||presence of biological impurities||Ideal choice of water purifier|
|Below 300 ppm (Soft water)||No||No||Gravity based purifiers|
|Below 300 ppm (Soft water)||No||Yes||UV/UF water purifiers|
|Below 300 ppm (Soft water with impurities)||Yes||Yes||UV/UF Water Purifiers|
|Over 300 ppm (Hard water)||No||No||RO Water Purifier with TDS Controller|
|Over 300 ppm (Hard water with impurities)||Yes||Yes||RO + UV/UF water purifier with TDS Controller or Mineralizer|
Factors to consider while buying water purifiers
Now, you have a clear idea about the nature of impurities in the water. You have an as to which water purifier to choose to tackle the kind of impurities.
You should always conduct the test of the water source at your house before deciding the type of water purifier to opt for.
1. Do the TDS evaluation test to determine the amount of TDS in water.
2. If you live in an area inhabited by industries, it is better to conduct a chemical test of the water source to determine the level of industrial pollutants.
3. If in doubt, you can always go for the best, i.e. the RO + UV + UF water filters. However, remember these filters are comparatively expensive as compared to the other water filters.
4. Your budget plays a very big role in deciding the kind of water purifier you choose. While determining the budget, you should also factor the cost of maintenance and replacement of filters.
Understand the drawbacks of the RO water purifiers
The RO water purifiers employ the best water purification techniques. However, they have a major drawback in the sense that they waste a lot of water. In fact, they waste more than 50% of the input water. In this era of water shortage, this is a criminal wastage.
You have uses for the RO wastewater. However, the water that comes out as the wastewater contains a high proportion of TDS.
Therefore, there is a need to dilute the water before using it to water your plants, cleaning the floors, etc. Also, Have a look at 12 simple ways you can save water in everyday life.
