Industrial Filter Ultrafiltration Equipment for Water Treatment Solutions
Filter ultrafiltrationis a mainstream physical separation filtration technology widely used in industrial water purification, wastewater reuse and pure water pretreatment fields, relying on microporous membrane materials to intercept harmful impurities in water under low pressure driving force.

This paper comprehensively explains the structural composition, internal filtration operation principle, unified technical indicators, strict whole-process quality inspection standards and multi-industry practical application scenarios of filter ultrafiltration equipment. Global water treatment purchasers, engineering contractors and factory operation managers can fully understand the advantages of our filter ultrafiltration products, stable production supply capacity and complete after-sales service system, so as to select matched ultrafiltration filtering devices to optimize enterprise water treatment costs and stabilize long-term effluent quality standards.
Filter ultrafiltration equipment is a complete integrated filtering system that uses ultrafiltration membrane as the core filter medium, equipped with supporting power, flushing, dosing and automatic control modules to complete continuous water body filtering work automatically. Our filter ultrafiltration series takes two mainstream membrane materials: modified hydrophilic PVDF organic hollow fiber membrane and inorganic alumina ceramic membrane as the core filter layer, and integrates stainless steel frame, raw water booster pump, backwashing pump, chemical cleaning dosing tank, security pre-filter and PLC intelligent control cabinet into one set of integrated equipment. All finished filter ultrafiltration devices will pass hydraulic tightness test and 72h full-load running debugging before leaving the factory, realizing on-site simple pipeline docking and fast commissioning operation.
We build a differentiated product matrix to satisfy diverse filtering demands of different projects. Conventional factory circulating water filtration, general reclaimed water recovery projects can directly adopt our stock Ultrafiltration equipment, with low comprehensive cost and stable basic filtering performance and short delivery cycle. For projects with special water quality, limited installation area and customized water volume parameters, customers can sign up for our tailor-made Custom Ultrafiltration System service, where our technical team optimizes membrane quantity, pipeline material and overall frame layout according to actual on-site working conditions. Large water plants and centralized industrial water supply stations mostly choose mass-produced Professional Ultrafiltration Machine, which adopts assembly line standardized processing to ensure unified product quality for bulk orders. For printing and dyeing, chemical wastewater with high organic pollutant content, the reinforced hydrophilic Organic Membrane Ultrafiltration System can slow down membrane fouling speed effectively and cut daily manual maintenance workload. For high-temperature, strong corrosive harsh water environments, wear-resistant and long-life Advanced Ultrafiltration Ceramic Membrane is the preferred filter ultrafiltration configuration solution.
The frame and internal pipelines of standard filter ultrafiltration equipment adopt SUS304 stainless steel by default; SUS316L stainless steel and anti-corrosion coating are optional for corrosive wastewater treatment conditions. The whole filtering system supports unattended automatic operation, with differential pressure interlock protection, automatic backwashing and timing chemical cleaning functions, greatly reducing the manual operation threshold for end users. As the direct manufacturer without intermediate dealers, we can provide customers with scheme optimization, long-term spare parts supply and full-cycle technical after-sales support for filter ultrafiltration systems.
Filter ultrafiltration adopts cross-flow filtration mode instead of dead-end filtration, taking low liquid pressure as driving force to complete physical screening and interception through the tiny pore structure on the ultrafiltration membrane wall. The overall operation is divided into three core working modes: normal filtering water production, automatic backwashing and regular chemical cleaning.
Raw water is pressurized by the feed pump and evenly delivered into each membrane component inside filter ultrafiltration equipment. The membrane pore size is controlled steadily between 0.01~0.1μm. Water molecules and tiny soluble inorganic ions pass through membrane pores smoothly to form qualified clear water for subsequent production use. Suspended solids, colloids, bacteria, algae and macromolecular organic pollutants are trapped on the inner surface of hollow fiber membranes. Most raw water flows along the membrane surface tangentially to form cross-flow scouring water flow, continuously washing away pollutant sediments to maintain stable membrane flux during long-time continuous filtering operation.
Pollutants will accumulate gradually on the membrane surface after long-term filtering, causing the pressure difference between the raw water side and produced water side to rise continuously. When the numerical value hits the preset threshold, the PLC system will automatically start the backwashing program. The produced clean water is used for reverse flushing from the water outlet side to the raw water side to peel off surface dirt and discharge sewage out of the filtering system through the sewage pipeline. The backwashing process takes a short time and will not interrupt the continuous water supply of the filter ultrafiltration system.
Long-term operation will produce organic dirt, biological slime and inorganic scale inside membrane pores, which cannot be completely removed by physical backwashing. The supporting acid-base dosing device of filter ultrafiltration equipment is used for circulating soaking cleaning to remove stubborn pollutants thoroughly, restore the original flux of membrane elements and prolong the service life of core filter membrane components.

Q1: What is the essential difference between filter ultrafiltration and ordinary precision filter?
A: Precision filters only intercept large particle impurities through filter elements, while filter ultrafiltration relies on molecular-level membrane pores to intercept colloids, bacteria and macromolecular organics, with deeper filtering effect and automatic self-cleaning flushing function.

A: Yes. Our professional design team completes scheme design and parameter matching according to customer demand data, supporting full non-standard customization of filter ultrafiltration systems.
Q3: What is the delivery time of spot filter ultrafiltration equipment and customized filter ultrafiltration systems?
A: Conventional Ultrafiltration equipment is in stock with delivery within 3–7 working days; customized filter ultrafiltration systems take 10–20 working days according to configuration complexity.
Q4: What pretreatment devices need to be installed in front of filter ultrafiltration equipment?
A: It is recommended to equip multimedia filter + 5μm security filter to intercept large particulate impurities, reduce membrane pollution load and effectively extend the service life of ultrafiltration filter membranes.
Q5: What parts are covered by the warranty of filter ultrafiltration equipment, and which are not covered?
A: Stainless steel frame, pumps, valves and PLC control system enjoy 1-year global free warranty; ultrafiltration filter membranes are consumables and not within the warranty scope.
Q6: Can multiple sets of filter ultrafiltration equipment run in parallel to expand the total water processing capacity?
A: Completely feasible. Multiple filter ultrafiltration units can be connected in parallel on the main pipeline with unified central control, convenient for customers to expand water treatment capacity in stages.
