1. Product Introduction of Ultrafiltration Filtration Equipment
Ultrafiltration filtration equipment takes modified PVDF ultrafiltration membrane as the core filtering medium, matched with feed pumps, backwashing pipelines, online chemical cleaning assemblies, pressure monitoring instruments and PLC intelligent control cabinet to form an automatic closed filtration system. Compared with traditional sand filtration, bag filtration and cartridge filtration, ultrafiltration filtration realizes stable interception effect at the micron and molecular level, with stronger shock resistance against raw water quality fluctuations and lower later manual maintenance intensity.
LEFILIER classifies ultrafiltration filtration equipment according to installation space, pollution load and water production capacity of on-site projects. For factory renovation projects with narrow installation areas and short construction periods, users can select compact frame-style Industrial Skid Mounted Ultrafiltration Equipment. All pipelines, instruments and control cabinets are fixed on an integrated stainless steel skid base; customers only need to connect water pipes and power supply on site to complete startup debugging, greatly shortening the project delivery cycle. For high-pollution wastewater such as printing & dyeing wastewater, landfill leachate and chemical tail water, wide runner Tubular Ultrafiltration Membrane avoids pollutant deposition inside membrane tubes, presenting excellent anti-fouling performance under long-term high-load continuous operation. For small food processing plants, commercial water supply stations and laboratory water preparation, integrated cabinet-type Integrated Ultrafiltration Water Purification Equipment integrates all functional modules inside the equipment shell, with built-in automatic backwash and medicament cleaning programs without additional supporting facilities. For large municipal reclaimed water plants and chemical park centralized pure water stations, the fully tested Complete Ultrafiltration Integrated Equipment supports parallel operation of multiple membrane groups to meet large-flow continuous water production requirements.
Our ultrafiltration filtration equipment uses oxidation-resistant, acid-base resistant modified PVDF hollow fiber and tubular membranes. The main frame is made of standard 304 stainless steel, while 316L stainless steel can be customized for corrosive wastewater environments. The PLC control system supports differential pressure pollution alarm, timed automatic backwashing and regular chemical cleaning reminders, realizing 24-hour unattended automatic operation. At present, ultrafiltration filtration equipment has become an indispensable core filtering unit in modern industrial water treatment processes.
2. Working Principle of Ultrafiltration Filtration Equipment
Ultrafiltration filtration equipment adopts pressure-driven cross-flow filtration mode, which is divided into two working states: normal permeate production and membrane cleaning regeneration.
Permeate Filtration Stage
Raw water is pressurized by the feed pump to 1.0–3.6 bar and flows into the ultrafiltration membrane module. With 0.01~0.1μm uniform micropores on the membrane wall, water molecules and small soluble inorganic salts pass through the membrane smoothly to form qualified produced water for subsequent use. Suspended particles, colloids, microorganisms and organic macromolecules are trapped on the outer surface of hollow fiber membranes. Part of the fluid flows rapidly along the membrane surface to form cross-flow concentrated water, scouring most intercepted pollutants out of the system to prevent dense filter cake accumulation on the membrane surface.
Membrane Cleaning & Regeneration Stage
After long-term operation, partial pollutants will adhere to the membrane surface and cause flux decline. The system automatically starts two cleaning modes: regular backwashing uses clean produced water to flush membrane pores reversely and wash away loose surface dirt; periodic CIP chemical cleaning uses sodium hypochlorite, alkali liquor and dilute acid to decompose biological slime and organic fouling, restoring the original flux of ultrafiltration membranes and guarantee the stable water output efficiency of the filtration system for a long time.

4. Product Quality & Manufacturing Assurance
Xinxiang Lifeierte Filter Corp., Ltd implements full-process quality supervision for all ultrafiltration filtration equipment from raw material incoming inspection to finished product delivery. Each batch of membrane elements passes 100% bubble point test and tensile test to eliminate hidden dangers such as fiber fracture and water leakage. Stainless steel frames and pipelines adopt precision argon arc welding technology, and air tightness pressure tests are carried out after welding to avoid pipeline leakage during long-term operation.
Every finished ultrafiltration filtration equipment must complete FAT factory acceptance test under simulated actual working conditions before delivery. Professional inspectors test water yield stability, differential pressure fluctuation, backwashing effect and program response one by one to ensure stable operation after equipment arrives at the customer site. Our filtration equipment has ISO9001 quality system certification and CE safety certification. With standardized operation and routine maintenance, the service life of PVDF ultrafiltration membranes can reach 5–8 years. We supply global spare parts and provide free remote technical commissioning guidance for all customers purchasing our ultrafiltration filtration equipment.

FAQ
Q1: What is the essential difference between ultrafiltration filtration equipment and ordinary precision cartridge filters?
A: Precision filters can only intercept large particle impurities, while ultrafiltration filtration relies on microporous membrane structure to block colloids, tiny organic matters and bacteria. Meanwhile, ultrafiltration equipment supports automatic backwashing and chemical cleaning with longer stable service cycles.
Q2: Why is cross-flow drainage designed for ultrafiltration filtration equipment?
A: High-speed cross-flow fluid continuously scours the membrane surface to take away intercepted pollutants, slow down membrane fouling speed and extend the service cycle of ultrafiltration membranes.
Q3: How often should ultrafiltration filtration equipment perform chemical cleaning in daily operation?
A: For clean raw water working conditions, the cleaning cycle is 4–6 months; for polluted wastewater, chemical cleaning is required every 1–3 months according to actual operating pressure difference data.
Q4: Can ultrafiltration filtration equipment remove dissolved salts in water?
A: Ultrafiltration only intercepts particulate and macromolecular substances and cannot filter dissolved ions and salts. If desalination treatment is needed, it must be matched with reverse osmosis equipment.
Q5: What failures will occur if polluted ultrafiltration membranes are not cleaned for a long time?
A: The equipment water yield will drop sharply, system operating pressure difference will keep rising, and irreversible membrane pollution will occur in serious cases, leading to premature scrapping of expensive membrane components.
Q6: Can ultrafiltration filtration equipment realize 24-hour unattended automatic operation?
A: Our standard ultrafiltration filtration equipment is equipped with a complete PLC automatic control system, which supports automatic backwashing, fault real-time alarm and cleaning cycle reminder, realizing long-term unattended stable operation.
