Best ultrafiltration water treatment system 2021 (how does it work)

Ultrafiltration water treatment is the water purification process that uses membrane technology to remove suspended particles in the water.

Ultrafiltration membrane

Ultrafiltration water treatment uses a hollow fiber membrane to remove solid particles that are on the water.

Ultrafiltration water treatment is commonly referred to us as UF. 

How does ultrafiltration water treatment work?

Ultrafiltration membrane pore size

Ultrafiltration membrane has a pore size which is less than 0.01 to 0.1 mm. 

Ultrafiltration uses hollow fibers of a semi-permeable membrane that is large.

Water is passed through the hollow fibers and pressure is applied across the membrane.

Suspended particles and large impurities are filtered while water passes through the membrane.

Advantages of Ultrafiltration membrane

  • No electricity is required to operate-UF water purifier doesn’t require electricity to operate you only need pressure from the ordinary tap water.
  • Removes large particles from the water
  • No need for annual maintenance cost- It is easily maintained by manually removing blocked particles from a membrane
  • They are affordable compared to RO and UV water purifier
  • It’s safe because no chemical is required in the process
  • It doesn’t alter the taste or odor of water since no chemical is added.
  • Remove all dead cells from water- when compared with a UV water purifier that kills the microorganism’s bodies but doesn’t remove the dead cells from the water.
  • Suitable for soft water but not hard water.
  • Compatible with another method of purification
  • If you take proper care, it can last up to 10 years
  • A UF membrane is tough and doesn’t break easily so will never provide polluted water.

Disadvantages of Ultrafiltration Water treatment

  • It is not effective on its own. It’s effective when combined with another method of purification.
  • Doesn’t remove dissolved impurities in the water
  • Cannot be used in water containing high TDS level

What ultrafiltration membrane removes

ultrafiltration vs reverse osmosis

The only different UF has large pores of membranes while RO has small pores.

UF purification rejects very tiny particulate or solids while RO removes dissolved minerals in the water.

Ultrafiltration method is best for tap water because this water is already treated by the municipal and mostly doesn’t contain germs, dissolved particles, and total dissolved salt (TDS) level is within the required limit.
