Ultrafiltration water treatment (What it is and contaminants removed)

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

After all suspended particles have been removed the membrane allows fresh water and dissolved minerals to pass through.

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. 

The hollow fiber membrane has a pore size of 0.01 micron, so when water goes through the membrane any suspended particles that are larger than 0.025 microns are removed.

To give you an idea of how the system removes all suspended particles from the water on a micro-scale, let’s take an example of human hair, a human hair is typically 75-80 microns in diameter, and the UF membrane pore size is 0.01. This means that an ultrafiltration system removes all suspended particles from the water on a tiny level.

What does Ultrafiltration remove from water?

As said earlier ultrafiltration water treatment uses a UF membrane that helps remove suspended particles from the water that are larger than 0.025 microns.

Such contaminants include inorganic solids, viruses, and bacteria.

What the ultrafiltration membrane does remove is dissolved minerals like the reverse osmosis system.

Types of ultrafiltration water treatment

There are three types of ultrafiltration water treatment. This includes point of use, point of entry, and portable.

Both the point of use and point of entry work the same and use a UF membrane that has a pore size of 0.01 micron. The only difference is the location of the installation.

The point of use system is installed anywhere you need filtered water. Such places include under the sink Read further Under sink ultrafiltration water filter, others are countertop and portable. The system is just for cooking and drinking.

Point of entry is installed on your incoming water line. It is also called the whole house ultrafiltration system. The system treats all water coming to your house, therefore providing clean water for cooking, drinking, bathing, gardening, cleaning, and other home uses.

Ultrafiltration membrane is also used Portable water filters for filtering drinking water direct from rivers, lakes and other outdoor water sources.

Advantages of Ultrafiltration membrane

  • No electricity is required to operate-UF water treatment system 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
