Types of Water Purifier and Mapping them According To The Type Of Water Sample

Do you know what a water purifier is? Here in this post we will be discussing various kinds of water purifiers in detail so keep reading this article til the end. 

  • Reverse Osmosis (RO) Purifier

To comprehend the working of RO water purifier, one first needs to understand what osmosis is. Generally, in the process of osmosis – the water moves from a space of low solute focus (low TDS level), through a semipermeable membrane, to high solute fixation (high TDS level). The pores of the layer are tiny (around 0.0001 microns), water particles being smaller are permitted to go through, and the small broken up pollution and microbes are caught.

As the name proposes, Reverse Osmosis (RO) does something opposite to Osmosis, which is pushing the water particles from the area of higher TDS level to the area of lower TDS level. It is done by applying outer strain with the assistance of a water siphon to turn around the regular progression of water. Water with pollution or high TDS is pumped at high pressure into the RO chamber – this pushes the water atoms across the semi-penetrable layer to the opposite side while leaving the broken down solids and different contaminations.

Reverse Osmosis Process

RO purifiers are subsequently consistently suggested for cleansing water that has a high TDS level. The TDS level of the drinking water from the RO purifier is extremely low when compa111110red with the input water.

A few Drawbacks of RO Technology

Requires Electricity: A high-pressure electrical water siphon is used to apply outside pressure on the input water. Thus RO purifiers can’t work without power.

Water is Wasted (a lot of it): Water is discharged alongside the filtered and purified contaminations, which causes unnecessary wastage of water but an advanced water purifier recover almost all water lost during the purification process. By and large, RO purifiers produce 3 litres of wastewater for each 1 litre of cleaned water.

  • Ultrafiltration (UF)

Like RO, Ultrafiltration additionally utilizes a semi-penetrable layer to purify water. You might now think if both – RO and UF utilize a similar strategy to purify the water, then what is the difference between RO and UF. Ultrafiltration or UF water purifier uses a film with a lot bigger pores (appx. 0.01 microns) when compared with RO. RO utilizes a film with tiny pores (appx. 0.0001 microns).


The upside of utilizing Ultrafiltration is UF purifiers can work without power because the layer has a lot bigger pores, and water can go through it using gravitational energy. It implies no outer tension or water siphon is required. Likewise, since UF purifiers don’t keep down any water, there is no wastage of water.

Yet, there are a few restrictions on utilizing UF purifiers. Due to the bigger pore size, UF can only eliminate undissolved solids and bigger debasements. It can’t purify the broke up solids or decrease the TDS level. Thus, UF purifiers are not appropriate for the purging of high TDS water or hard water.

3. Ultraviolet (UV) Purification

As the name proposes, Ultraviolet or UV purifiers utilize light beams for the cleaning of water. A UV purifier works by tossing focused UV beams on the water – which kills or inactivates the illness-causing microscopic organisms and infections.

Be that as it may, UV purifiers can’t eliminate any disintegrated or un-dissolved debasements or synthetics from water. On which account, most of the UV purifiers accessible in the market – utilize some kind of external sediment pre-filters to eliminate undissolved contaminations and an enacted carbon channel to remove Chlorine and some disintegrated pollutants.

Subsequently, UV water purifiers are only recommended for regions where the water source has a low degree of TDS.

If the water has a low TDS level but is filled with microbes and infections and seems muddy, then you can utilize a UF+UV water purifier.

4. Tap/Faucet Filters or Gravity Based Purifiers

These types of channels or purifiers are the least complex to use and give the most basic water decontamination. These channels, for the most part, involves – sediment or sediment + activated carbon filters. It can eliminate enormous and un-disintegrated contaminations like mud and sand – alongside certain chemicals and microorganisms. Tap/Faucet Filters are tiny and can be fitted on taps.

Tap/Faucet Filter and Gravity Based Purifier

Gravity-based capacity purifiers are the high-level variant of tap/fixture channels. These purifiers offer marginally progressed filtration and accompany an in-constructed capacity tank to store input water. The majority of the Gravity-based water purifiers accessible in the Indian market presently have two separate stockpiling tanks. One for input and the other for cleansed water.

Tap/Faucet Mounted Filters and Gravity Based Purifiers are reasonable for regions where the TDS level is low. The water isn’t too polluted with natural debasements like microscopic organisms, infections and other illness-causing microorganisms.

Which Water Purifier Should You Choose?

Along these lines, when we talk about purchasing a water purifier, the vast majority thinks that RO water purifiers ought to be bought. But the thing is, the need for a water purifier is dependent on what kind of water you have. Get your water lab-tested before you decide to buy a water purifier – RO UV Purifiers, UF Purifiers or Gravity Based Purifiers.
