Buyer's Guide: Types of Water Purifiers – RO, UV, UF, and Gravity Filters

You must remember there were days when we had to boil water before drinking it; Still we do it for small kids as they are more prone to viruses. In north part of India many house families buy packaged water for daily drinking. However very few invest in water purifiers and water filters. The water purifiers are a bit expensive but consumers are opting for it because it is considered to be the best bet against unsafe or contaminated water. The market for water purifiers – ranging from simple filters and gravity-based purifiers to those with latest technologies such as Reverse Osmosis (RO), Ultrafiltration (UF) and Ultraviolet (UV) and their combinations – is growing tremendously and various brands are available in each category.

View the below image which will demonstrate why to you need a Water Purifier.

Let’s look into the Types of Purification Methods

1) RO PURIFIERS OR REVERSE OSMOSIS PURIFIERS

RO technology pushes the water molecules from a region of higher TDS level to one of lower TDS level by applying external pressure with the help of a water pump to reverse the natural flow of water. Water with impurities or high TDS is pumped at high pressure into the RO chamber, and this pushes the water molecules across the semi-permeable membrane to the other side while leaving the dissolved solids and other impurities behind. All the dissolved solids and impurities along with some input water, also known as RO wastewater, are discharged through a separate outlet.

Reverse Osmosis

The Bureau of Indian Standards (BIS) has specified the maximum TDS limit for safe drinking water as 500 ppm (500 milligrams per litre). There is absolutely no need to use an RO purifier if the TDS level is below 300 ppm. If your water source has low TDS, then the RO purifier will further reduce it to a very low TDS level. This means the purified water will then be devoid of essential minerals like calcium and magnesium which are required for our good health. Very low TDS may also not be acceptable to consumers due to its insipid taste.

RO purifiers are therefore recommended for purifying water that has high TDS level. However, there is also the fact that a significant part of the input water is discharged along with the dissolved impurities, which results in unnecessary wastage of water. On an average, RO purifiers produce 3 litres of wastewater for every 1 litre of purified water.

2) UV WATER PURIFIERS OR ULTRAVIOLET PURIFICATION

This technology uses ultraviolet rays for the purification of water. A UV purifier works by throwing high-intensity UV rays on the water which kills or inactivates the disease-causing bacteria and viruses. However, UV purifiers cannot remove any dissolved or undissolved impurities or chemicals from water. Because of this, most of the UV purifiers that are available in the market use some form of external sediment pre-filters to remove undissolved impurities and an activated carbon filter to remove chlorine and some dissolved impurities.

UV water purifiers are only recommended for areas where the water source has low level of TDS. If the water has low TDS level but is contaminated with bacteria and viruses and appears muddy, then you can use a UF+UV water purifier.

3) UF WATER FILTERS OR ULTRAFILTRATION (UF)

Ultra-filtration uses a semi-permeable membrane with much larger pores (approximately 0.01 microns) as compared to an RO (which has very small pores, of approximately 0.0001 microns).

The advantage of UF purifiers is it can work without electricity because the membrane has much larger pores and water can pass through it naturally using the force of gravity. This means no external pressure or water pump is required. Since UF purifiers do not hold back any water, there is no wastage of water.

There are some limitations, though. Because of the larger pore size, UF can only remove undissolved solids and larger impurities. It cannot remove the dissolved solids or reduce the TDS level. So, UF purifiers are not suitable for purification of high TDS water or hard water.

4) Gravity Filters

These types of purifiers are very common and mostly seen in villages and it is the simplest and most basic water purification. These filters generally comprise of sediment or sediment + activated carbon filters which can remove large and un-dissolved impurities like mud and sand along with some chemicals and microorganisms. Tap/Faucet Filters are very small in size and can be directly fitted on taps.

Pre checks before you buy a Water Purifier!

1) Water Quality:

The first thing to consider when buying a water purifier is the quality of the water supply you get in your home. The quality of the water supply depends on the water source. If the water supply in your home is supplied by municipalities and it comes from natural resources like lakes, rivers, and rainwater harvesting techniques, then you’re getting soft water. If the water supply in your home comes from underground sources like borewells, tube wells, hand-pumps, and wells then you’re getting hard water. The amount of total dissolved solids (TDS) is comparatively higher in hard water than soft water. However, if you are receiving hard water, opt for an RO water purifier. In case if the water quality is soft then opt for a UV water purifier. In case of hard water and as well as highly contaminated water, then go for RO+UV water purifiers.

2) Types Of Water Purifiers:

Which we have already discussed in our above section. (RO, UV, UF and Gravity Filters)

3) Installation:

A few water purifiers are designed to be used as a countertop kitchen appliance while some brands also manufacture water purifiers that can be hung on the wall to keep the countertop clutter-free. Decide upon a suitable place for your water purifier – countertop or wall and then make a final decision.

4) Storage Capacity:

If your family size is big or you reside in an area that has frequent power cuts or unreliable water supply; Then go for a water purifier that has a larger storage capacity. This will ensure a continuous supply of pure and contamination-free drinking water.

5) Certification of Purity:

Another point to consider when purchasing a water purifier is a certification of purity. Most brands these days usually give a certificate of purity with the water purifier. This certificate is a mark of the authenticity of the brand. It also ensures that the water dispensed from the water purifier is of high quality and therefore safe to drink. Water purifiers usually have one or two of the following certifications.

IS 16240: 2015 standard covers Reverse Osmosis (RO) based point of use water treatment system.

IS 7402:1986 /2011 standard certifies that the ceramic filters used in the purifier can arrest impurities to the finest range possible, including particulate and bacterial impurities.

NSF, WQA, ISI, and CE are some of the other certifications to look for when selecting a water purifier.

IS 14724: 1999 indicates that the purification process is carried out through a combination of UV film and rays.

IS 10500:2012 gives an assurance that the end product is free from coliform, pesticide residues and other chemical contaminants.

6) After Sales Services:

The saddest part of water purifiers is that it requires frequent servicing. Poor after-sales services can cause a lot of problems and the customers have to wait for a longer time to get their problems solved. Therefore, before making any final decision on which water purifier to purchase, do enquire about the after-sales services offered by the brand.

7) Digital Display:

Most water purifiers come with basic display for purifier on/off, a tank full, etc. Some advanced purifiers also come with an LED display that shows fault alert, membrane change, UV fail, TDS level indicator, purity indicator, etc.

8) Mineral Fortification Technology:

Some advanced water purifiers come with a mineral fortification technology that adds essential minerals which enhances the taste, quality and also balances the pH of purified water.

9) In-built TDS controller:

A few advanced water purifiers come with an in-built TDS controller that controls the TDS (Total Dissolved Solids) levels of water. When the TDS levels of input water are not so high, the TDS Controller can be used to increase the TDS of purified water to a healthy level.

10) Purification Capacity:

Purification capacity is the flow rate at which water is purified in an hour. A higher flow rate can result in an unsuccessful purification of water while a slower flow rate takes a lot of time to give you one liter of clean water. Therefore, go through the water purifier specifications carefully and look out for the purification capacity. Ideally, a purifier should give you anywhere between 10-14 liters/hour.

Frequently Asked Questions on Water Purifiers (FAQ)

There are two forms of impurities found in drinking water, suspended and dissolved:

a) Suspended impurities such as mud, dust, sand, bacteria, viruses, etc
b) Dissolved impurities that are soluble in water such as; pesticides, arsenic & fluoride and heavy metals salts like mercury, lead, copper, cadmium.

Please follow the steps and our Buyer’s Guide mentioned above which will surely help you in finding you your best water purifier.

Yes, All Water Purifiers require occasional attention and many require replacement filters & membranes. Follow the manufacturer’s recommended service and maintenance instructions.

No, It is not true and it is a misconception!

RO Water Purifiers do not reduce any essential minerals in your drinking water. It has a mineral modulator, specially designed to produce electromagnetic vibrations in the water. This helps prevent the mineral scale formation inside the UV chamber and helps in retaining the essential minerals in the water.

As per BIS (The Bureau of Indian Standards), the desirable quality of drinking water should have TDS (Total Dissolved Salts) content of 500 ppm (parts of the salt present in a million parts of water) or less. If at all, such quality is not available, the compromise level is water with up to 2000 ppm.

Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water fit for specific purposes.

Distilled water is water that has been boiled into vapor and condensed back into liquid in a separate container. Impurities in the original water that do not boil below or near the boiling point of water remain in the original container.
