What Are Differences Between RO and NANO Technology in Water Filtration System?

Home / What Are Differences Between RO and NANO Technology in Water Filtration System?


Water is an essential matter to maintain the life of human beings. In the major cities and densely populated areas, the demand for water is huge and growing day by day. However, there are plenty of places where the water purification system producing the pure water does not comply with the safety and hygiene standards of the Ministry of Health. It not only affects people’s health but also is the primary cause of diseases.

The water filtration system using RO technology with six membranes ensures the quality of food safety. Not only that, this device is equipped with a system that adds liquid minerals to the treated water.

Therefore, the water after being treated is not only clean and pure but also full of beneficial minerals, which is good for health. So with the best reverse osmosis system, the users can drink the water directly from the tap without boiling.

To help you distinguish the types of water purification that are being sold on the market, I will introduce two technologies being widely used today in the production lines of pure water.

1. The water filtration system using reverse osmosis technology (RO technology)
The reverse osmosis membrane (abbreviated as RO or RO membrane) is approximately 0.0001 microns in size. This device is commonly used in desalination and demineralization to produce the pure and fresh water.
In the past, RO technology was a very limited and small-scale production due to its high cost. Besides, the technology was not accessible so that the reverse osmosis system was only applied in the household filter system. Currently, this technology has been extended thanks to its advantages.
2. The water filtration system using NANO technology
The NANO membrane that is also called Nanofiltration (abbreviated as NF) has lots of tiny pores. These pores are about 0.001 micrometers in size. The NANO technology is capable of removing multivalent ions as well as the single-molecule organic matter in the water. So using the Nano filter for water softening is the best choice.
3. The advantages and disadvantages of two water filtration systems, Reverse Osmosis and Nanofiltration.
Both two water filter systems have their strengths and weaknesses. To help you can choose a suitable water filtration system for your respective units, we would like to give the necessary information that you should not ignore about the advantages and disadvantages of RO and NANO technology.

The advantages

RO technology (Reverse osmosis system): This is the most radical and advanced water filtration technology until the present time. Because the interstices of the membrane are tiny, about 0.001 micrometers in size and the operational mechanism of RO system is similar to the kidney, which produces pure water for using.


NANO technology: Because the interstices of the membrane of NANO technology are larger than the RO one, this device will not completely remove the mineral content in the water. Notwithstanding, these minerals are good or bad for health depending on the water source.

The disadvantages

The reverse osmosis system also takes out completely all the minerals from the water. Meanwhile, without the process of rough handling, the membranes of NANO system can be clogged easily. Besides, the remaining minerals after treated may negatively affect health. Furthermore, the cost is always higher than other types of water filters.

The different filtering processes between the membranes depend on the size of the particles that need to be eliminated. Hence, the various membranes will remove different types of particles in the water source. Based on the above information, you partly understand the fundamental differences between RO and NANO water filtration system. If you are looking to get a good product, the article above will be useful. Thanks to that, you can choose the best solution to pure water for your household. Wish you always use clean water to ensure health for you, your family and the whole community.
