Product Description


Ultrafiltration (UF) System
Ultrafiltration (UF) System is a pressure-driven membrane separation technique situated between microfiltration and nanofiltration, primarily used for the separation, purification, and concentration of macromolecules, colloids, particulates, and pathogens in solutions. The pore size of UF membranes generally ranges from 0.01 to 0.1 micrometers, allowing water, solvents, and small molecular substances to pass through while effectively retaining most microorganisms, proteins, polysaccharides, colloids, and particulate matter.

Components of the Product:
The main components of the ultrafiltration system include: pumps, bag filters, hollow fiber UF membranes, local instruments, dosing systems, fully automatic control systems, and a framework platform.

Product Parameters


Technical Principle:
The working principle of Ultrafiltration (UF) is based mainly on membrane separation technology. It is a physical separation process that uses a semipermeable membrane with specific pore sizes as the filtering medium. Under external pressure, as the mixture flows through the UF membrane, water molecules, solvent molecules, and some small molecular substances smaller than the membrane pores can smoothly pass through, while larger molecules, colloidal particles, microorganisms, and pathogens larger than the pore size are retained on the upstream side of the membrane, thus achieving purification, separation, or concentration of the solution. The specific process is as follows: 
Feed delivery: The liquid to be treated (such as water, solutions, or slurries) enters the UF system at a certain pressure.
Separation process: When the feed contacts the UF membrane, only components smaller than the membrane's pore size are allowed to pass through. For instance, if the pore size is 0.01-0.1 micrometers, then small molecular substances like water molecules and ions can pass through, while bacteria, viruses, large organic molecules, and colloidal particles are blocked.
Permeate and retention: Small molecular substances that pass through the membrane form the permeate, which is typically quite pure; whereas, larger molecules retained by the membrane accumulate on the upstream side, forming a concentrated solution or what is known as the UF retentate.
Cleaning and regeneration: Over time, the UF membrane surface may have material deposition, adsorption, or even scaling, leading to a decrease in membrane flux. Therefore, regular chemical cleaning or physical backwashing is required to restore the membrane's separation performance.

Product Features/Advantages:
The characteristics and advantages of hollow fiber UF membranes mainly include the following aspects:High filtration precision: The pores of hollow fiber UF membranes are extremely small, usually less than 0.1 micrometers, effectively removing microorganisms, colloids, diatoms, and other fine impurities from water, ensuring the quality of the output water.Good hydrophilicity: After special processing, hollow fiber UF membranes have excellent hydrophilicity, enabling high water production rates even under low-pressure environments, and also possess anti-fouling and anti-scaling properties.High mechanical strength: The mechanical strength of hollow fiber UF membranes is better than that of general UF membranes, with a higher resistance to broken filaments, ensuring stable operation and a longer service life of the UF membrane.Strong resistance to chemicals and oxidation: Hollow fiber UF membrane materials have good resistance to chemicals and oxidation, allowing for stable operation in various harsh environments without being easily oxidized or corroded.Good cleanability: If a hollow fiber UF membrane becomes clogged, it can be cleaned using various methods to restore its original performance and extend its service life.Strong adaptability: Hollow fiber UF membranes are suitable for various water quality conditions, especially in the field of industrial wastewater, such as textile wastewater, chemical wastewater, coking wastewater, etc.In summary, hollow fiber UF membranes have the advantages of high filtration precision, good hydrophilicity, high mechanical strength, strong resistance to chemicals and oxidation, good cleanability, and strong adaptability. Therefore, they are widely used in water treatment, beverage processing, wastewater treatment, and other fields.
