Hollow Fiber Ultrafiltration Membrane Equipment for Industrial Water Purification

Hollow fiber ultrafiltration membrane equipment is a mainstream membrane separation device adopting PVDF hollow fiber membrane filaments, widely deployed in raw water purification, wastewater reuse and desalination pretreatment across industrial and municipal sectors. It can work alongside Tubular Ultrafiltration Membrane for Heavy Polluted Water Treatment to build multi-stage separation workflows, and match Desalination Ultrafiltration System to provide stable pretreatment feedwater for seawater reverse osmosis units. Featuring high packing density, compact structure and automatic operation, this equipment efficiently intercepts suspended solids, colloids and microorganisms. It remains one of the most cost-effective membrane filtration solutions favored by global water treatment contractors and factory operators.

Product Description

Hollow fiber ultrafiltration membrane equipment refers to the complete automated water treatment system centered on hollow fiber ultrafiltration membrane modules. The core component, hollow fiber membrane, consists of countless tiny polymer fiber tubes with uniform micropores on the wall. Compared with plate and tubular membrane forms, hollow fiber designs deliver higher membrane area within limited space, significantly improving unit space water production capacity. The full set includes hollow fiber membrane assemblies, raw water lift pumps, backwashing pipelines, chemical cleaning dosing units, online water quality sensors and PLC control cabinet.

End users can select standalone skid-mounted hollow fiber ultrafiltration membrane equipment for medium-small water treatment stations. For complex wastewater containing high viscosity pollutants, projects can add supporting Tubular Ultrafiltration Membrane for Heavy Polluted Water Treatment to handle fluid that cannot be processed directly by hollow fiber systems. For coastal desalination facilities, multiple sets of this equipment can be configured to form complete Desalination Ultrafiltration System, stabilizing SDI and turbidity of seawater before reverse osmosis desalination. This equipment is compatible with surface water, groundwater and secondary sewage effluent. It serves as reliable pretreatment equipment for pure water systems, circulating water replenishment and industrial wastewater recycling projects in food, pharmacy, chemical and municipal environmental protection industries.

Working Principle

Hollow fiber ultrafiltration membrane equipment operates on low-pressure cross-flow membrane separation technology. Raw water enters the membrane module and flows outside or inside hollow fiber filaments under stable operating pressure ranging from 0.1 MPa to 0.3 MPa. Water molecules and soluble small ions pass through membrane wall micropores and converge as clean permeate water.

Suspended particles, algae, colloids, bacteria and macromolecular organic substances larger than membrane pore sizes are trapped on the membrane surface, and discharged continuously through concentrated water pipelines. Continuous cross-flow scouring reduces pollutant accumulation and prevents rapid membrane fouling. The system executes timed automatic backwashing to flush surface contaminants, and periodic chemical cleaning recovers membrane flux once obvious attenuation occurs. For high-pollution complex wastewater, pre-matching Tubular Ultrafiltration Membrane for Heavy Polluted Water Treatment removes large particles in advance to protect hollow fiber membrane components. In seawater desalination projects, multiple groups of hollow fiber membrane equipment are combined into a complete Desalination Ultrafiltration System, ensuring long-term stable pretreatment water quality for reverse osmosis desalination membranes.
