Currently on the market of direct drinking water purifiers , there are 3 most interesting water purification technologies : RO (REVERSE OSMOSIS), NANO (NF – NANO FILTRATION) and UF (ULTRA FILTRATION). To have a more specific look at these technologies, let’s find out and compare the advantages and disadvantages of each with Scimitar.
RO water purification technology
RO water purifier technology is actually a reverse osmosis membrane, appearing in the world and present on the Vietnamese market for a long time.
RO (reverse osmosis) technology is the most advanced and thorough water purification technology available today. Because the openings of the RO membrane filter are 0.001 micrometers in size, like the working mechanism of the human kidney, it prevents all kinds of substances, bacteria, viruses, etc., from being discharged. This technology will produce completely pure water (pure water).
Advantages:
Suitable for many water sources: tap water, well water…
Produces 99.9% pure water
Wide range of capacity suitable for small scale family to large scale in industrial production
Various models
Weaknesses:
RO filtration technology will produce pure water, and also completely remove minerals in water (drinking purified water for a long time makes the body lack some essential minerals).
Consume a lot of water, because producing pure water means removing the same amount of wastewater
Need to use electricity
How to fix:
The new technology of the RO water purification system has added the function of adding beneficial minerals to the body, namely adding a fine filter and creating minerals in the final filtration step.
The amount of waste water can be reused for things such as watering plants, washing clothes, cleaning the house, etc.
Nano water purification technology
New to the business market although the technology dates back to the 80’s. Nanotechnology has larger openings than RO but smaller than UF. This will also filter bacteria and viruses, but not completely remove the mineral content. However, whether the remaining substances will be completely beneficial or not, there is no answer because it depends on the input water source.
Advantages:
Compact, no electricity, no waste water
Fewer cores are generated during use
Easy to install and replace by yourself
Weaknesses:
Only suitable for relatively stable quality input water sources such as tap water
Nano technology without a rough treatment system will easily cause membrane blockage, the remaining minerals in the water may not be beneficial to the body, high cost.
How to fix:
With the filtration technology of the Nano water purifier, users must determine the water source in advance to use Nano more effectively.
UF . water purification technology
UF (UltraFiltration) membrane, also known as ultrafiltration membrane, is a filtration technology that uses low-pressure membranes to remove large molecules from water. Under a pressure domestic water purifier machine price in bangladesh of not more than 2.5 bars, water, mineral salts and molecules / ions smaller than the filter hole (0.1 – 0.005 micron) will “pass” through the membrane easily. Larger molecules, harmful viruses and bacteria will be prevented.
Advantages:
Compact, no electricity, no waste water
Fewer cores are generated during use
Easy to install and replace by yourself
The membrane can be discharged during use
Weaknesses:
Only suitable for relatively stable quality input water sources such as tap water
The remaining minerals in the water may not be beneficial to the body
How to fix:
It is necessary to clearly identify the source of input water, the physical and chemical criteria need to meet the standards of domestic water sources of the Ministry of Health (Water Department).
Each water purification technology has its own advantages and disadvantages. The most important thing is to choose the right filter technology for your needs, such as input water quality, usage capacity… See tips on choosing a water purifier according to your needs here .
