What is UF filter technology? Working principle and application

When learning about water purifiers, there are many models that are integrated with UF filter technology and are “praised” by the company for many health benefits that you are particularly impressed with but do not understand what this technology is? Let’s find out quickly with Tnhelearning.edu.vn.

What is UF filter technology?

UF (Ultra Filtration or Ultrafiltration) technology is a technology that separates contaminants from water by using UF membranes.

Ultrafiltration membrane is composed of hollow fiber membrane with pore size from 0.01 – 0.1 m white tubular (as small as 1/5000 of the size of a hair with a thickness of 50 – 70 m) when water goes from the outside to the bottom. Pressure from the filter membrane of mud, impurities, suspended solids, bacteria, viruses will be retained while the clean water will go deep in the filter membrane, giving the filtered water a cleaner, more pure.

The UF membrane differs from the RO membrane in one prominent point that while the RO can filter very small particles, the UF can filter larger particles.

Working principle

There are 2 operating principles of UF filter technology: the principle of operation from outside to inside and from inside to outside, specifically as follows:

– Principle of operation from outside to inside : The membrane position is inside, the filter layer is outside, the water flow is pushed from the outside to the inside, impurities, dirt, bacteria are kept outside while the water is clean. enters and collects on the inside of the ultrafiltration membrane.

– Principle of operation from the inside out: The membrane is outside, the filter layer is inside, the water flows in the direction from the inside of the membrane, impurities, dirt, bacteria are kept inside and only clean water flow out.

Advantages and disadvantages of UF . filter technology

Advantage

– Filtering operation takes place under normal temperature conditions from 0 ~ 35°C, low pressure conditions from 1 ~ 5 bar, low power consumption or no electricity needed to minimize costs for users.

– Use UF filter to filter dirt, do not use chemicals.

– Does not generate as much wastewater as RO membranes.

– Homogeneous structure and materials do not change the chemical properties of water.

– The material is insoluble, does not mix with water.

– The system is compact, does not take up space, is easy to install, simple to operate, and saves labor costs.

Defect

– UF filter does not filter well for hard water because it does not remove dissolved solids, if you want to use it with hard water, you need to use additional filtering equipment to ensure safer water for health.

Applications of UF . filtration technology

Currently, this filter technology is used in many different fields, which can list some prominent common areas of use:

– Water purifier in family, company, factory.

– Used to produce bottled water, juice, energy drinks.

– Food and beverage production lines.

– Disinfect industrial water, remove dirt, colloids, suspended solids.

– Industrial fermentation, application in pharmaceutical technology concentration, purification, cleaning.

– Filtering water for aquaculture.

– Treatment of industrial wastewater, reuse of water.

– Sterilization, removal of turbidity in the wine production process.

Can water filtered through UF filter technology be drunk directly?

The structure and materials that make up the filter membrane are made uniformly filtered by mechanical methods, the materials do not penetrate – dissolve into the water source, do not affect to change the water properties after filtration and at the same time when the water has undergone The filtration process from UF filtration technology, the mud, impurities, bacteria, viruses present in the water have been retained, the water that comes out is of high purity, the user can completely drink it directly without having to boil. boil again.
