5 Types of advanced water purification technologies

While shifting to a new apartment and organizing. I had to look for a water purifier that can provide me some clean, fresh and most important pure water, which free from impure and harmful substances. Since the tap water can still be contaminated. It was very hard for me to trust the water we got from the locality so I wanted to get a water purifier as soon as possible. While I looked upon the internet, there were hundreds of choices. But, with my patience, I could list five types of advanced water purification technologies. In this article, I am going to provide you the information which could help you pick a water purifier for pure and clean water.

The five advanced water purification technology:

The new technology used uses a membrane technology for water purification along with a UV lamp filter. Here are some common methods of water filtration for domestic purposes.


RO purification, known as reverse osmosis is commonly used for water purification. The RO uses a membrane technology that can eliminate impurities, germs and dissolved salt from water. If your tap water contains is high in TDS (Total Dissolved Solids). The RO purification should be the first thing on your list. The RO purification has a semi membrane that can separate germs and dissolved chemicals. The membrane has fine pores that allow the purified water to pass through while it collects the microbes, harmful chemicals and dissolved salt to stay suspended in water.

The drawback with RO purifiers is it may remove essential minerals from water.


The UF filtration does a similar kind of job like the RO purification. However, its membrane has bigger pores. The UF filtration doesn’t require electricity and kills bacteria, viruses, cysts and other microbes present in water. It works better with public supply water. Somehow, it fails to remove the dissolved solids and salts from water. It works better with less TDS in water.


The UV purification is also known as e-boiling purification. The UV purification uses a simple process of using a UV light. The UV light kills all the germs, viruses, bacteria, cysts and microbes present in the water.  The simple strategy can kill up to 99.99% of the harmful organisms. The short wave UV radiation produced by the small tiny mercury lamp can destroy the bacteria or virus by penetrating its cells. This stops them from reproduction, as the microbes can multiply, it leads them to die.

The UV purification somehow cannot filter the dead bodies of the germs. So, it needs a separate filter to remove microbes. Generally, it comes with a partnership with RO purifiers below 15000.


The Candle Filter purifier does not need electricity to operate. The candles used in them have minute pores which block any larger size particles from passing by to the cleaner water section. However,

It cannot block the microbes and water still needs to be boiled for use.


The Activated Carbon Filter is a non-electrical purifier; it uses carbon filter for purification; the carbon filter can remove chemicals like chlorine, pesticides, and impurities to a wide extent. The downside is it changes the taste and odor of water and is ineffective in removing microbes.


In my consideration, it is important if you can conduct a water test on the tap water available at your house. This will help you select the water purifier depending on the need.
