Industrial Ultrafiltration Membrane Filter Equipment for Water Treatment
Ultrafiltration membrane filter equipment is a mainstream membrane separation device that uses porous ultrafiltration membranes to intercept colloids, suspended solids and microorganisms in water, widely applied in raw water pretreatment, wastewater reuse and liquid purification in all industries.

Ultrafiltration membrane filter equipment takes modified hydrophilic PVDF hollow fiber membrane as the core filter medium. The complete system consists of ultrafiltration membrane modules, stainless steel support frame, raw water feed pump, backwashing assembly, chemical cleaning dosing device, security pre-filter and PLC automatic control cabinet. It can automatically complete water production, online backwashing and regular chemical cleaning without frequent manual operation. All finished equipment will pass air tightness test and 72 hours full-load continuous operation debugging before delivery to guarantee long-term stable operation on site.
We build a gradient product system to satisfy different project demands. For simple small-scale water purification demands, customers can choose economical Hollow Ultrafiltration Equipment to complete basic impurity removal work. For overall water treatment station construction projects, the assembled Ultrafiltration UF System realizes unified pipeline layout and automatic program linkage control. For printing and dyeing, chemical wastewater with high organic content, upgraded High Performance Industrial Ultrafiltration Equipment effectively slows down membrane fouling rate and reduces cleaning frequency. In enterprise energy-saving and water-saving reconstruction projects, optimized Ultrafiltration Water Reuse Equipment improves system water recovery rate and maximizes water resource utilization efficiency. For factories with 24-hour continuous production, wear-resistant Durable Ultrafiltration Equipment Device matches the main membrane system to prolong the overall service life of the filtering equipment.
The frame and pipelines of ultrafiltration membrane filter equipment adopt SUS304 stainless steel as standard material; SUS316 stainless steel is optional for corrosive wastewater environment. The control system supports pressure difference real-time monitoring, automatic backwash triggering and remote data viewing, greatly reducing manual management pressure. As the direct manufacturer without intermediate distributors, we provide customers with scheme calculation, installation guidance, membrane element replacement supply and full-cycle technical support services.
Ultrafiltration membrane filter equipment operates on the cross-flow filtration principle, taking pressure difference as driving force, and uses the physical screening effect of membrane micropores to separate impurities from water body. The whole working cycle is divided into three core working modes: normal water production filtration, automatic backwashing, periodic chemical circulating cleaning.
Original water is pressurized by feed pump and flows into the inner cavity of hollow fiber membrane filaments. The pore size of ultrafiltration membrane is stably controlled at 0.01~0.1 μm. Water molecules and tiny soluble substances penetrate the membrane wall outward to form qualified produced water for subsequent RO treatment or direct reuse. Suspended particles, colloids, bacteria, algae and macromolecular organics are trapped inside the hollow fiber. The tangential high-speed flow of raw water continuously scours the membrane inner wall to inhibit the accumulation of pollutant cake layer and maintain stable membrane flux during long-term operation.
With the continuous accumulation of intercepted pollutants, the pressure difference between feed side and produced water side gradually rises. When the numerical value reaches the system preset threshold, PLC will automatically open the backwash valve. Clean produced water reversely washes the membrane filaments to peel off surface dirt, and the concentrated wastewater is discharged out of the system. The backwash process is short and will not cause long-time system shutdown.
Physical backwashing cannot eliminate organic slime, biological attachments and inorganic scale deposited in membrane pores after long-term operation. The supporting acid-base dosing system performs circulating soaking cleaning to thoroughly remove stubborn pollutants, restore the initial flux of ultrafiltration membrane and ensure the efficient operation of the filter equipment for a long time.
