Leveraging the high - precision screening technology of ultrafiltration membranes, ultrafiltration equipment effectively intercepts impurities such as bacteria, colloids, and macromolecular organic matter in water. With the advantages of high - efficiency purification and low - cost operation, it becomes the preferred solution for water treatment in industrial and civil fields.
Ultrafiltration is a membrane separation technology that can purify and separate solutions.The ultrafiltration membrane system is a solution separation device with ultrafiltration membrane silk as the filter medium and the pressure difference on both sides of the membrane as the driving force.It only allows the solvent (such as water molecules),inorganic salts and small molecular organic substances in the solution to pass through,while retaining the macromolecular substances such as suspended solids,colloids,proteins and microorganisms in the solution,so as to achieve the purpose of purification or separation.
Raw Water Inlet: The raw water enters the equipment through the water inlet and is transported to the ultrafiltration membrane module via pipelines.
Pressure - driven Filtration: Under a pressure of 0.1 - 0.3MPa, the raw water flows outside the membrane. Water molecules and small - molecule substances pass through the membrane pores to form produced water, while bacteria, colloids, suspended solids, macromolecular organic matter, and other substances with a particle size larger than 0.01 - 0.1μm are retained on the membrane surface.
Produced Water Collection and Concentrated Water Discharge: The produced water that passes through the ultrafiltration membrane is collected and output through the produced water pipeline, and the concentrated water that fails to pass through is discharged from the concentrated water outlet, carrying impurities.
Backwash Maintenance: After operating for a certain period, the equipment automatically initiates the backwash program. The produced water flushes the membrane surface in the reverse direction, removing attached impurities, restoring membrane flux, and extending the membrane service life.

Can ultrafiltration equipment remove heavy metal ions in water?
Ultrafiltration mainly intercepts macromolecular substances and colloids, and has limited effect on removing heavy metal ions. For heavy metal removal, it is recommended to combine with reverse osmosis or ion exchange equipment.
How often do ultrafiltration membranes need to be replaced?
Under normal conditions, the service life of ultrafiltration membranes is 3 - 5 years. If the raw water quality is poor or the water production significantly decreases, the membrane elements need to be inspected and replaced in a timely manner.
How is the equipment backwash frequency set?
The backwash frequency can be set according to raw water quality and operating time, generally automatically backwashing once every 1 - 3 hours of operation, lasting 30 - 60 seconds each time.
Ultrafiltration equipment has become an important guarantee in the water treatment field, thanks to its micron - level screening filtration technology, efficient and stable operation performance, and wide applicability. Whether it is to ensure the safety of domestic drinking water or meet the high - standard water demand of industrial production, efficient purification can be achieved through customized configurations. In the future, with the improvement of environmental protection requirements and water quality, ultrafiltration equipment will continue to optimize membrane materials and intelligent control technology, providing green and reliable water treatment solutions for more industries.
