3.1 – 9.3 m3 /hr 77 m² PVDF Dow Ultrafiltration Membrane Modules SFP-2880 / SFD-2880
The UF2880 hollow ultrafiltration membrane of the United States is a membrane separation technology. Its process is a solution separation process based on the principle of mechanical screening and driven by the pressure difference on both sides of the membrane. In addition to screening, the interception of substances also includes physical and chemical effects such as adsorption, repulsion, and bridging. In the field of water treatment, it can be used to remove particles, colloids, bacteria, viruses, heat sources, proteins and high molecular organic matter from water to purify water.
Application of UF2880 hollow ultrafiltration membrane of the United States:
Drinking water preparation: The current situation of water shortage and increased surface water pollution threatens the source of human cloud water. DowTM SFP series ultrafiltration products have high filtration accuracy and extremely high removal efficiency for microorganisms. Through the sanitary inspection of relevant national departments, it provides economical and reliable protection for your drinking water safety.
Reverse osmosis pretreatment: UF2880 hollow ultrafiltration membrane of the United States provides a more stable and high-quality water source for the reverse osmosis system, protects the reverse osmosis system from pollution and blockage, and greatly extends the life of the reverse osmosis system. DowTM SFP series ultrafiltration products are widely used in reverse osmosis pretreatment systems in my country's power, petrochemical, petroleum, electronics and other fields, with a daily water treatment capacity of more than 600,000 tons.
Reuse of industrial wastewater and municipal sewage:
UF2880 hollow ultrafiltration membranes from the United States can remove suspended solids, colloids, organic matter and other impurities in industrial wastewater and municipal sewage, providing pretreatment guarantees for the deep treatment and reuse of wastewater and sewage. DowTM SFP series ultrafiltration products, 8-inch diameter components have a large dirt holding capacity, and the tough PVDF membrane fibers withstand more frequent water, gas, and chemical cleaning, while ensuring high-throughput filtration efficiency. Suitable for industrial wastewater, municipal sewage reuse, etc.
Seawater filtration
The excellent performance of the UF2880 hollow ultrafiltration membrane from the United States completely replaces the traditional treatment methods of coagulation, sedimentation and multi-media filtration. In many reverse osmosis seawater desalination systems at home and abroad, it provides high-quality and stable water inlet for seawater desalination reverse osmosis systems, and establishes the application of seawater resources.

Ensuring that the UF system is properly started is critical to preparing the membrane for operation and preventing potential membrane damage. Following the correct startup sequence is essential to maintaining system parameters within design specifications, helping to achieve water quality and productivity goals.
Before beginning the startup procedure, membrane preconditioning, membrane module installation, instrumentation calibration, and system checks must be completed per the guidelines outlined in the product technical manual.
To prevent membrane damage, sudden pressure changes during startup, shutdown, cleaning, or other sequences should be avoided. Before startup, flush the UF system thoroughly to eliminate any remaining shipping solution. In addition, purge any residual air from the system before commencing operation.
Start the unit manually, with the goal of achieving an initial permeate flow rate of 60% of the design capacity. Depending on the application, it may be necessary to discard the permeate obtained during initial operation. Refer to the product technical manual for detailed instructions.
General information
If operating limits and guidelines given in this bulletin are not strictly followed, the limited warranty (Form No. 795-00027) will be null and void.
To prevent biological growth during system shutdowns, it is recommended that preservative solution be injected into the membrane modules.
Regulatory note NSF/ANSI 61 certified drinking water modules require specific conditioning procedures prior to producing potable water. Please refer to the product technical manual flushing section for specific procedures. Drinking water modules may be subjected to additional regulatory restrictions in some countries. Please check local regulatory guidelines and application status before use and sale.
