Hollow fiber ultrafiltration equipment takes modified hydrophilic PVDF hollow fiber membrane filaments as the core filtering medium, which is arranged in bundles and sealed inside the membrane housing to form independent ultrafiltration membrane modules. The complete equipment set consists of hollow fiber membrane components, stainless steel support frame, raw water delivery pump, online backwashing assembly, chemical dosing cleaning device, front security filter and PLC automatic control cabinet. As the critical front-end protection equipment for reverse osmosis devices, it intercepts colloids, suspended solids, microorganisms and macromolecular organic pollutants in raw water, effectively lowering the SDI value of RO influent and greatly extending the service life of expensive reverse osmosis membrane elements. All finished hollow fiber ultrafiltration equipment undergoes air tightness inspection and 72-hour full-load continuous operation debugging before factory delivery to guarantee stable long-term field operation.
We provide differentiated matching schemes for hollow fiber ultrafiltration equipment according to customers’ different RO equipment configurations. For mobile field water supply projects such as mines and construction sites, the plug-and-play Standard Containerized RO Unit is matched with modular hollow fiber ultrafiltration devices to realize rapid deployment without complicated civil construction. For chemical factories, metallurgical plants and other outdoor installation environments, corrosion-resistant Outdoor Industrial Reverse Osmosis Equipment works stably with reinforced hollow fiber ultrafiltration assemblies under drastic temperature and humidity changes. For centralized water stations of industrial parks and large pure water workshops, high-volume Large-scale RO Equipment is combined with array-type large-flow hollow fiber ultrafiltration equipment to meet tons-level uninterrupted water production demand. For most conventional factory pure water preparation projects, the mature universal Industrial RO System forms the most cost-effective standard water treatment process with conventional hollow fiber ultrafiltration equipment. For small factories and laboratories with limited indoor installation space, miniaturized Integrated Reverse Osmosis Unit can be perfectly paired with compact small-sized hollow fiber ultrafiltration equipment to save workshop floor space.
The frame and pipeline of hollow fiber ultrafiltration equipment adopt SUS304 stainless steel as standard material; SUS316 stainless steel can be customized for high-salinity and corrosive wastewater working conditions. The built-in PLC control system supports differential pressure real-time monitoring, automatic backwash triggering and remote data access, which largely cuts down daily manual management pressure. As the original manufacturer without intermediate distributors, we provide customers with process scheme calculation, installation technical guidance, long-term membrane element spare parts supply and lifelong free remote technical support services.
Hollow fiber ultrafiltration equipment operates based on the cross-flow physical screening principle, using pressure difference as the driving force to complete impurity separation inside the hollow fiber tube cavity. The complete working cycle is divided into three core working modes: normal water production filtration, automatic backwashing and periodic chemical circulating cleaning.
Raw water is pressurized by the feed pump and flows into the inner cavity of hollow fiber filaments. The fixed pore size of hollow fiber membranes is controlled steadily at 0.01~0.1 μm. Water molecules and tiny soluble substances penetrate the membrane wall outward to form qualified permeate water for subsequent reverse osmosis treatment. Suspended particles, colloids, bacteria and macromolecular organic substances are trapped inside the hollow fiber lumen. The tangential high-speed flow of raw water continuously scours the inner wall of the membrane to slow the accumulation of pollutant filter cake and maintain stable membrane flux during long-term continuous operation.
With the gradual accumulation of intercepted pollutants, the pressure difference between the feed side and the produced water side rises continuously. When the value reaches the preset threshold of the control system, the PLC will automatically open the backwash valve. Clean produced water washes the hollow fiber filaments reversely to peel off surface dirt, and the concentrated wastewater is discharged out of the system. The backwash process takes a short time and will not cause long-term shutdown of the whole water treatment system.
Physical backwashing cannot completely remove organic slime, biological attachments and inorganic scale deposited in membrane pores after long-term operation. The matched acid-base dosing system carries out circulating soaking cleaning to eliminate stubborn pollutants thoroughly, restore the initial flux of hollow fiber membranes, and ensure the high-efficiency and low-energy operation of ultrafiltration equipment for a long time.
