Industrial Hollow Fiber Ultrafiltration System for Water Treatment Needs
The hollow fiber ultrafiltration system has become the most mainstream membrane separation device in industrial water treatment, relying on bundled hollow fiber membrane filaments to complete physical purification of raw water and wastewater under low-pressure driving force. Our factory develops and manufactures a full series of industrial liquid filter products based on hollow fiber membrane technology, including standard Hollow Ultrafiltration Equipment, integrated Ultrafiltration UF System, mass-produced products from our Trusted Ultrafiltration Equipment Factory, high-strength High Performance Industrial Ultrafiltration Equipment and recycling-oriented Ultrafiltration Water Reuse Equipment, covering small skid-mounted units to large centralized hollow fiber ultrafiltration systems with processing capacity up to 200m³/h. This paper elaborates the structural composition, cross-flow separation mechanism, unified technical indicators, strict whole-process quality management and diversified industrial application scenarios of hollow fiber ultrafiltration systems. Global purchasers, water treatment integrators and enterprise operation departments can fully grasp the performance advantages, stable delivery capacity and complete after-sales system of our hollow fiber ultrafiltration products, so as to select matched membrane filtration solutions to stabilize effluent quality and reduce long-term water treatment operating costs.
A complete hollow fiber ultrafiltration system takes modified hydrophilic PVDF hollow fiber membrane as the core filtering medium. Countless tiny hollow fiber filaments are assembled into membrane modules, which are fixed on the metal frame together with booster pumps, backwashing pumps, chemical dosing cleaning devices, security filters and PLC automatic control cabinets to form an integrated automatic filtration system. All finished hollow fiber equipment is subjected to hydraulic pressure test and 72-hour full-load running debugging before leaving the factory to realize quick docking and commissioning after arriving at the project site.
We have built a complete product gradient for different project demands. Conventional water purification projects can directly purchase spot Hollow Ultrafiltration Equipment, with low cost and stable basic filtering performance and fast delivery speed. For complete water treatment projects requiring overall matching, customers can choose the integrated packaged Ultrafiltration UF System, with unified design of pipeline layout and automatic program logic. As a professional Trusted Ultrafiltration Equipment Factory, we support bulk wholesale for global engineering merchants and provide stable batch delivery guarantee. For wastewater with high suspended solids and high organic pollution load, the reinforced High Performance Industrial Ultrafiltration Equipment can effectively slow down membrane fouling. In zero-discharge and water recycling projects, the specially optimized Ultrafiltration Water Reuse Equipment improves water recovery rate and maximizes water resource utilization rate.
The frame and pipelines of the hollow fiber ultrafiltration system adopt SUS304 stainless steel as standard configuration; SUS316L material is optional for corrosive wastewater working conditions. The system supports unattended automatic operation, with differential pressure alarm, automatic backwashing and regular chemical cleaning linkage functions, greatly lowering manual operation difficulty for users. As the direct production manufacturer without intermediate links, we provide scheme optimization, long-term membrane replacement supply and full-cycle technical support for all hollow fiber ultrafiltration system customers.
The hollow fiber ultrafiltration system adopts cross-flow filtration mode, uses low water pressure as power, and completes impurity interception through the microporous structure on the wall of hollow fiber filaments. The whole operation is divided into three core working states: normal water production filtration, automatic backwashing, periodic chemical cleaning.
Raw water is boosted by the feed pump and enters the inner cavity of hollow fiber membrane filaments. The pore size of hollow fiber membrane is stably controlled at 0.01~0.1μm. Water molecules and tiny soluble ions penetrate the membrane wall outward to form qualified produced water for subsequent use. Suspended solids, colloids, bacteria, algae and macromolecular organic substances are trapped inside the hollow fiber filaments. Most raw water flows along the inner wall of the fiber at a certain flow rate to form cross-flow scouring, washing away accumulated pollutants and maintaining stable membrane flux during long-term operation.
With the accumulation of intercepted dirt, the pressure difference between the feed side and the produced water side rises continuously. When reaching the set threshold, the PLC system automatically starts the backwashing program. Clean produced water reversely washes the inner wall of hollow fiber filaments to flush off surface pollutants and discharge sewage out of the system. The backwashing process is short and will not interrupt continuous water supply.
Long-term operation will lead to organic dirt, biological slime and inorganic scale inside the hollow fiber membrane pores, which cannot be eliminated by physical backwashing alone. The supporting acid-base dosing system carries out circulating soaking cleaning to thoroughly remove stubborn pollution, restore the initial flux of hollow fiber membranes and extend the service life of core membrane components.
