FupengWater has more than 23 years of experience as a global supplier of ultrafiltration systems, and its products are designed to reliably remove suspended solids, turbidity, bacteria, pathogens and viruses from water. These systems are economical, compact, and offer reduced clogging and higher solids loading. UF membranes ensure the highest filtration performance and high flux, and have excellent chemical resistance and tolerance to temperature changes.
How do UF systems work?
UF systems use a variety of membrane filtration technologies that use hydrostatic pressure to push solvents through very fine membranes. They block larger suspended particles and solids, while allowing water and lower molecular weight solutes to flow through the membrane.
This separation process is used by industry and research to purify and concentrate large molecular (103 - 106 Da) solutions, which are typically protein solutions. UF is similar to microfiltration, nanofiltration, or gas separation, except that the molecular size of the cutoff is different.
To meet stringent discharge standards, UF systems eliminate the need for clarifiers and multimedia water filtration. Highly efficient UF systems use submersible, backwashable, and air-flushed membranes. Spiral-wound UF/MF membranes excel in process water and wastewater purification.
Advantages of Ultrafiltration (UF) Systems
Ultrafiltration (UF) membrane systems are more reliable than conventional multimedia filters, which remove material approximately 10 microns or larger, while UF membranes have pore sizes ranging from 0.01 to 0.10 microns. In addition to superior turbidity removal, UF membranes effectively remove bacteria and most viruses.
Excellent filtration performance with high throughput
Very small nominal pore size (0.03 µm)
Effective removal of bacteria and viruses
Occasional backwashing and air scouring to improve performance and remove fouling layers for extended life
Low fouling membrane elements
UF outside-in or inside-out configurations reduce plugging and increase solids loading
Basic, vertical, modular design allows for low-cost, compact systems
Effective membrane cleaning with high chemical and temperature resistance
What is Ultrafiltration in Water Treatment?
UF systems utilize hollow membrane fibers to remove suspended solids, bacteria, viruses, and pathogens from feed water. A pump delivers treated water into microscopic pores that act as a physical barrier, allowing only the filtrate to pass through. Next, an ultrafiltration filter is used to remove solid matter such as weeds and plastics from the filtered water before it enters the ultrafiltration system. Ultrafiltration equipment has always played an important role in water and wastewater treatment, continuously providing excellent results. The water treated by ultrafiltration can be sent to the reverse osmosis system for further purification, or it can be directly used by the public.
What is ultrafiltration (UF) equipment and why is it important?
Most parts of the world use ultrafiltration equipment to ensure an adequate supply of clean water for public drinking. The water filtration efficiency of the ultrafiltration system is about 250 times higher than that of traditional media filtration systems. These devices are also very suitable for many industries that require ultrapure water. The ultrafiltration membranes used in these devices can reduce turbidity or be used as pretreatment to maintain the effectiveness of the reverse osmosis membrane. These devices are generally considered to be low-cost, easy to operate, no contamination residue, and a fairly high recovery rate.

You can use it to treat wastewater, concentrate proteins, separate chemical processes, separate oil/water emulsions, remove pathogens from milk, and clarify juice.
➣How does the ultrafiltration system work?
Ideally, ultrafiltration is a process that is performed when water needs to be purified immediately.
Ultrafiltration equipment works by using a membrane filtration process that acts as a barrier to separate harmful bacteria, viruses and other contaminants from clean water.
Suspended solids and high molecular weight solutes (such as pathogens, germs, and bacteria) are too large to pass through the membrane and stick to the outer membrane surface, allowing only fresh water and dissolved minerals to pass through.
A carbon filter is installed in the system to remove unpleasant odors and tastes as well as suspended solids.
➣ What is the difference between ultrafiltration and nanofiltration?
Ultimately, they both perform the same function; the main difference between ultrafiltration systems and nanofiltration is the pore size of the membrane.
The pore size of the ultrafiltration system filter is 0.01 microns, which can block everything. In contrast, nanofiltration has a pore size of about 0.001 microns, which cannot remove dissolved compounds and is usually used in industrial pure water manufacturing.
➣ What are the different types of ultrafiltration systems?
There are two types of ultrafiltration systems: point-of-use ultrafiltration systems and point-of-entry ultrafiltration systems.
Point-of-use is used for undercounter drinking water systems to treat all water that flows into your home, while point-of-entry is usually used for running water applications and is installed directly into the water supply pipe where filtered water is not required. They can work together to provide a complete solution for drinking water and whole-house needs.
➣What is the production process of ultrafiltration devices?
A water purification system that uses pressure to separate suspended solids and high molecular weight solutes in water through various membrane filtrations, and retains these solids in the retentate by blocking them. In contrast, water and low molecular weight solutes pass through the membrane filtration and enter the permeate.
It captures and removes physical solids in water through semi-permeable membranes.
It only allows water, minerals and some dissolved solids to pass through the filter and exit through porous and hollow fiber membranes that can hold all unwanted particles.
Ultrafiltration is one of the most popular choices for comprehensive under-sink water filtration.
➣How much does ultrafiltration equipment cost?
