1. Product Introduction of Ultrafiltration Membrane Separation Equipment
Ultrafiltration membrane separation equipment adopts high-performance polymer membrane materials as the core separation medium, achieving efficient water purification via low-pressure physical sieving filtration. Differing from traditional water treatment technologies such as sedimentation tanks and sand filters, membrane separation technology delivers consistently stable water quality output, requires minimal floor space, and supports highly automated operation. For this reason, it has become a vital pretreatment core device in modern industrial water treatment systems. We primarily utilize modified PVDF hollow fiber membranes and organic tubular ultrafiltration membranes, which feature outstanding antifouling performance and superior acid-base tolerance. These durable membrane components adapt perfectly to complex working conditions, including high-turbidity raw water, high-organic wastewater, and moderately corrosive industrial sewage across diverse industries.
A full set of ultrafiltration membrane separation systems consists of membrane module assemblies, corrosion-resistant stainless steel support frames, raw water transfer pumps, automatic backwash valve groups, online acid-base chemical cleaning dosing devices, front-end security liquid filter units, and PLC intelligent control cabinets. Through precise physical membrane separation, the system effectively purifies raw water to meet strict inlet water standards for reverse osmosis, nanofiltration and other advanced desalination equipment. Every finished unit undergoes strict air tightness testing and 72-hour full-load aging operation before delivery, ensuring long-term stable and continuous on-site operation for various water treatment projects.
We offer diversified ultrafiltration membrane separation solutions to cater to personalized project requirements. Enterprises requiring integrated filtration and desalination processes can opt for the Ultrafiltration Equipment Reverse Osmosis Combined Water Treatment System to achieve one-stop water purification. For projects with special requirements for water flow, equipment layout and complex water quality, we provide tailor-made production services via Ultrafiltration Equipment Company Providing Custom Water Treatment. Clients in need of matched ultrafiltration and reverse osmosis complete sets can select standardized solutions from Professional Manufacturer of Ultrafiltration and Reverse Osmosis Equipment. General industrial circulating water and production water purification scenarios adopt the cost-effective Ultrafiltration Membrane Water Treatment Equipment for Industrial Use. Meanwhile, high-flow and high-efficiency water purification projects are equipped with High Efficient Hollow Fiber Ultrafiltration Equipment to maximize overall water treatment productivity.
Standard equipment frames and pipelines are constructed with SUS304 stainless steel, while SUS316L stainless steel is optional for saline, acidic and alkaline wastewater scenarios to prevent electrochemical corrosion and extend service life. The intelligent control system supports local touchscreen operation and optional remote real-time monitoring for convenient daily management. Our factory provides in-stock standard equipment, non-standard customized design, OEM processing and complete CE certification, enabling overseas clients to complete customs clearance and project acceptance efficiently.
2. Working Principle of Ultrafiltration Membrane Separation Equipment
Ultrafiltration membrane separation adopts pressure-driven cross-flow filtration mode, and the built-in PLC program automatically switches three circulating working modes: normal water production filtration, automatic backwashing and regular chemical cleaning maintenance.
2.1 Normal Water Production & Membrane Separation Stage
Raw water first removes large particle impurities through the front-end liquid filter, and enters the inner wall of the ultrafiltration membrane under the pressure provided by the feed pump. The membrane aperture is fixed at 0.01~0.1μm, water molecules and tiny soluble ions pass through the membrane wall to form qualified purified water and flow into the subsequent water treatment unit. Suspended particles, colloids, bacteria, algae and macromolecular organic pollutants are trapped on the surface of the membrane filament. The high-speed flowing raw water continuously scours the membrane surface, slows down the accumulation speed of pollutant filter cake, and maintains stable water production flux during long-term operation.
2.2 Automatic Backwashing Regeneration Stage
With the continuous accumulation of intercepted pollutants, the pressure difference between the inlet and outlet of the membrane module gradually rises. When the pressure difference reaches the preset alarm value, the system automatically switches the pipeline valve group. Clean produced water flows in reverse to flush the loose dirt attached to the membrane surface, and the dirt is discharged out of the equipment together with concentrated water. The whole backwashing process only takes 3–8 minutes and will not cause long-term shutdown of the water treatment system.
2.3 Regular Chemical Deep Cleaning
Simple physical backwashing cannot thoroughly clean the stubborn biological slime and organic scale attached to the membrane pores. The supporting dosing system prepares dilute acid and alkali cleaning solution for circulating soaking cleaning, restores the original flux of the ultrafiltration membrane, and keeps the membrane separation equipment in efficient operation state for a long time.

FAQ
Q1: What obvious advantages does ultrafiltration membrane separation technology have compared with traditional physical filtration process?
A: Membrane separation relies on fixed pore size physical interception, and the effluent water quality is stable and will not fluctuate with the change of raw water turbidity. The equipment covers a small area, the automation degree is high to save manual labor, and the later maintenance workload is far lower than traditional sand filtration equipment.
Q2: Can the water output, pipeline material grade and automatic operation program be customized according to the customer's actual water quality test report?
A: Yes. Our technical team will match the membrane model, pump power and pipeline material according to the water quality data provided by customers, and optimize the backwashing and chemical cleaning program to complete targeted non-standard design solutions.
Q3: What is the delivery cycle of standard spot ultrafiltration membrane separation equipment and customized modified equipment?
A: Conventional standard equipment corresponding to High Efficient Hollow Fiber Ultrafiltration Equipment can be delivered within 3–7 working days; customized equipment with structural and parameter adjustments takes 12–28 working days according to the modification scope and processing difficulty.
Q4: What pre-filter devices need to be configured at the water inlet end of ultrafiltration membrane separation equipment?
A: It is recommended to install coarse filter + multimedia filter + security liquid filter at the front end to intercept large particle sediment, avoid physical scratch damage to membrane filaments, and reduce the overall pollution load of ultrafiltration membrane modules.
Q5: Which components of ultrafiltration membrane separation equipment are covered by the factory official warranty scope?
A: Stainless steel frame, water pumps, valve bodies, PLC control cabinet and detection instruments enjoy a 1-year global factory warranty; ultrafiltration membrane elements belong to consumable parts and are not included in the warranty scope.
