Water Purifier Types And Their Usage

Since many types of water purifiers are available in the market, we feel a compulsion to choose the best one according to our needs. Since the need for a specific water purifier service varies according to the amount of impurity in water, we look for options.

So, consumers should check out the source of their drinking water. Our source water contains many impurities, such as dust, debris, slits, hard metals, microorganisms like bacteria and viruses, dissolved solids, and other suspended solids. Therefore, let’s have a clear idea of different water purifier types which can be used to combat these impurities.

Water Purifier Types

So let’s get started with the types and their functionality.

  1. RO Water Purifier

Suppose, after thorough research, you have found out that your source water has high TDS (above 500ppm). Therefore, drinking water has become hard water, which is dangerous to health. In that situation, you can install an RO water purifier that works as a water softener.

As the name suggests, an RO ( Reverse Osmosis) water purifier differs from the normal osmosis process. It pushes the molecules of water from the higher TDS level to the Lower TDS level. With the help of a water pump, it applies external pressure and reverses the natural water flow. Therefore, with such high water pressure, it gets pumped straight to the RO Chamber. In this process, the semipermeable membrane of RO filters the dissolved impurities. Thereafter, all the impurities get discharged through a separate outlet.

Here Are Some Of The Components Of The RO Water Purifier

  • Sediment Pre-filter
  • Carbon Pre-filter
  • RO or UF membrane
  • UV filter
  • Carbon Post-filter
  • Storage tank

Therefore, as a water softener, an RO purifier is recommended mostly. The TDS level of the filtered water of RO is much better compared to other water purifiers. 

  1. Ultrafiltration or UF

Ultrafiltration is another filter used to purify water. Like RO, this filter uses semi-permeable membranes to purify and offer clean water; however, at first glance, it may seem that RO and UF are similar in their method of purification.

However, the membrane or pores of a UF technology has much larger pores than an RO membrane, which has much smaller pores. Therefore, a UF water purifier service cannot offer completely purified water.

The TDS or total dissolved solids are comparatively lesser through RO filtration. However, due to the larger pores of a UF system, those dissolved solids can pass through.

Though, there’s an advantage of using a UF purifier, as it can work without the need for electricity, as the membranes have larger pores. Therefore water can pass through the filter naturally with the gravitational force. In other words, there’s no need for external pressure or using any water pumps. Since the UF purifier doesn’t hold the water, there’s no possible wastage of water as well.

However, a UF purifier cannot filter total dissolved solids from water due to those problems above. It works well to filter hard particles and suspended solids.

  1. UV or UltraViolet Purification

This is another example of a water purifier. An ultraviolet water purifier uses UV rays to kill the biological pollutants in the water directly. It uses ultraviolet rays at a high intensity and completely changes the DNA compound of the microorganisms, such as bacteria, viruses. 

However, UV purifiers cannot eliminate total dissolved solids or suspended solids and other hard metals or rusts from the water. Therefore, most of the UV water purifiers in the market uses some sort of external features or sediment filters to filter out the un-dissolved solids, such as sand, slits, rusts, debris, and other metallic junks. In addition, there is a carbon filter that removes the chlorine contained in water as well as other forms of impurities,

Therefore, we only recommend UV water purifiers if the source water has a lower level of TDS. in addition, if there’s a chance of biological contaminants, and has a muddy appearance, then UV purifiers work really well.

  1. Gravity Based Purifiers

These water purifiers are perhaps the most basic and give only a basic level of water purifying service. Generally, these filters comprise of the sediment, or sediment + carbon filters. Those can be used to remove any large and suspended impurities, like rough dust, mud, sand, slits, and other chemical wastes and microorganisms.

Generally, faucet filters are very tiny in size. Therefore they can be easily installed onto the tap. Also, gravity-based purifiers are the better versions of the tap filters. Those have an in-built storage tank for water input.

These water purifiers are great for those areas where the TDS level is relatively less. Moreover, make sure that source water isn’t contaminated with biological impurities. Otherwise, it might not work as smoothly as expected.

Conclusion 

In the end, choosing the correct water purifier depends on your use and the impurities of your source water. If the source water has a higher TDS level ( hard water), then using RO service can benefit. In addition, if the hard water has biological contaminants, you can use a mix of RO+UV or RO+UV+UF purifiers. 

If the TDS level is relatively less and the water has the chance of getting contaminated with biological impurities, then a UV water purifier can be used. Moreover, if the source water has soft water ( lower TDS level), then UF or UV+UF water purifier is beneficial to your kitchen. Therefore, it all depends on the source of water and your own needs. There are many types of water purifiers in the market, so choosing the right one is necessary.
