What is Ultrafiltration ? Advantages of UF water purifier

UF water purifier

Ultrafiltration is a type of membrane filtration which is used to separate the suspended particles and impurities from the water. The process is very effective in removing bacteria, virus, cyst, microorganisms, & natural organic impurities and deliver pure and clean drinking water. UF water purifier uses a membrane which is similar to RO membrane, but the pore size is slightly larger than RO membrane. The biggest advantage of UF water purifier is that it does not require electricity to operate.  Therefore, such water purifier can be easily used in any areas where there is a regular issue with a power cut. Besides this, the filtration process is very simple & clean and it does not use any chemicals for the purification of the water. This ensures that the taste of water remains unaltered.

Advantages of UF water Purifier

Ultrafiltration water purifier has many advantages and these are mentioned below:

  • Works without electricity so you don’t need to worry about the power cut issue.
  • Remove a large number of suspended particles and can purify dirty & muddy water effectively
  • No chemicals are used so it does not change the taste of water
  • It provides pure drinking water which is better than boiled water because it washes out all germs, dirt, and cyst
  • No annual maintenance contract needed. UF membrane can run for a long time as compared to other purifiers. It can be easily cleaned by flushing blocked impurities on its own which saves your money
  • Durability is another advantage of UF water purifiers. The membrane is extremely strong, which cannot be cracked and this means that it will deliver longer service life.
  • Unlike UV water purifier, it physically removes all the germs and bacteria from the water. UV water purifier only kills the germs but their dead bodies still remain in the water. On the other side, ultrafiltration process stops those deadly microorganisms by blocking them to reach to the purified water.
  • Affordable price, which means that you can easily purchase at the price range of Rs.2000-6000, which is very less as compared to RO and UV purifier
  • Can be as good as RO purifier if the dissolved salt content is very less in water.
  • During RO water purification process a lot of water gets wasted, but UF water purifier does not waste a single drop water. You get the same output of water that you have poured for filtration.

Disadvantages of UF water Purifier

The only issue with UF water purifier is that it is not capable of removing dissolved salts from the drinking water. If the TDS level of the water is very high then UF water purifiers won’t be able to purify the supplied water. So it is very important to check the TDS level of your water before buying UF water purifier


How Does UF water purifier work?

UF water purifiers work on a principle of gravity which means that you pour impure water in the top section and it gets filtered and falls to the bottom section. This process can be done without applying any external pressure and it does not require any electricity for filtration. It can work with normal tap water pressure as well. The pore size of the membrane is small enough to restrict suspended particles and other microorganisms from passing through it. It delivers pure water which is free of the impurities.
