Wastewater treatment ultrafiltration equipment is specially optimized aiming at high turbidity, high organic matter, high suspended solids and biological sludge contained in industrial wastewater. It adopts anti-fouling modified hydrophilic PVDF hollow fiber ultrafiltration membrane as the core filter medium, with integrated skid-mounted frame design and automatic online cleaning system to cope with the easy fouling feature of wastewater medium. A complete set of wastewater ultrafiltration system consists of pollution-resistant UF membrane module bank, SUS304/SUS316L anti-corrosion frame, sewage delivery pump, concentrated water circulating pipeline, automatic backwashing assembly, acid-alkali chemical cleaning dosing system, front liquid filter protection unit and PLC intelligent control cabinet. Different from conventional water purification ultrafiltration equipment, this wastewater version enhances the membrane flux recovery performance and strengthens the pipeline anti-corrosion treatment, which can steadily intercept sludge, colloids, microorganisms, macromolecular organics and tiny suspended particles in biochemical effluent, stripping most pollutants from wastewater and producing qualified reclaimed water for production reuse or standard discharge. All finished wastewater ultrafiltration equipment undergoes air tightness pressure testing and 72-hour sewage medium simulation operation aging test before factory delivery to guarantee stable long-term operation under harsh sewage working conditions.
We develop differentiated ultrafiltration products to satisfy diversified wastewater treatment project demands. Projects requiring simultaneous sewage treatment and concentration separation can choose Integrated Ultrafiltration and Nanofiltration Equipment for Water Treatment to realize graded purification of wastewater. Factories that need unattended sewage operation are recommended to deploy intelligent Fully Automatic Ultrafiltration Equipment for Industrial Water to cut manual operation costs. For enterprises needing wastewater treatment + desalination together, the integrated Ultrafiltration and Reverse Osmosis Device forms a complete wastewater reuse water production line. Large sewage stations with massive wastewater discharge can select high-throughput 100 Ton Large Flow Ultrafiltration Equipment to meet bulk sewage treatment load demands. Conventional low-concentration domestic sewage and general industrial wastewater treatment can adopt the cost-effective Ultrafiltration Membrane Water Purification Equipment for basic advanced filtration treatment.
The frame and pipeline of standard wastewater ultrafiltration equipment are made of SUS304 stainless steel; SUS316L or FRP materials are optional for corrosive wastewater such as chemical, pickling wastewater. The built-in control system supports differential pressure early warning, timed automatic backwashing, regular chemical online cleaning and remote data monitoring functions. Our company provides standard wastewater UF equipment stock sales, non-standard flow layout customization, OEM processing and complete CE export certification documents to support customers to smoothly complete customs clearance in various countries and regions.
The equipment relies on pressure-driven cross-flow physical interception technology to purify wastewater, and the whole operating cycle is divided into three automatic circulating working modes: sewage filtration & water production, automatic backwashing, chemical cleaning for pollutant elimination.
After preliminary sedimentation and primary filtration of wastewater, sewage is pumped into the inner cavity of hollow fiber membrane filaments under feed pressure. The ultrafiltration membrane pore size is controlled at 0.01~0.1μm. Clean water molecules and small soluble inorganic substances pass through the membrane wall to form standard reclaimed water for recycling use. Pollutants like sludge, colloids, bacteria and organic macromolecules are trapped on the membrane surface or inside membrane tubes. The high-speed tangential flow of raw sewage continuously scours the membrane surface to slow down the accumulation of pollutant filter cake and maintain stable water production flux.
With the continuous deposition of intercepted pollutants, the inlet-outlet pressure difference of membrane modules will gradually rise. When the pressure difference value reaches the preset alarm threshold of PLC program, the system automatically switches pipeline valves. Clean produced reclaimed water reversely washes the membrane filaments to wash away loose surface contaminants, and sewage dirt is discharged out of the system with concentrated water flow automatically. The whole backwashing process is completed automatically without manual intervention and will not cause long-time shutdown of the sewage treatment system.
Physical backwashing cannot remove stubborn biological slime, organic attachments and tiny inorganic scales attached to membrane pores after long-term wastewater treatment. The supporting dosing system automatically prepares dilute acid and alkali liquid for circulating soaking cleaning, thoroughly recovers the original permeation flux of the pollution-resistant membrane components and keeps the wastewater ultrafiltration equipment running efficiently for a long time.
