Ultrafiltration-based water treatment filtration equipment uses modified polymer membrane as the core filter medium and realizes graded purification of raw water via physical sieving under low-pressure driving force. Comparing with traditional water treatment facilities such as sedimentation tanks, quartz sand filters and activated carbon filters, membrane-type water treatment filtration equipment has prominent advantages of stable water outlet quality, small floor occupation and high intelligent operation level, and has become essential pretreatment equipment in modern complete water treatment processes. The two mainstream membrane materials adopted in our production are modified anti-fouling PVDF hollow fiber membrane and organic tubular ultrafiltration membrane. Both materials own outstanding acid and alkali resistance and anti-pollution performance, and can stably operate in harsh water quality conditions such as high turbidity raw water, high-concentration organic wastewater and slightly corrosive industrial wastewater in chemical, mining, printing and dyeing industries.
A complete set of water treatment filtration equipment consists of membrane module components, stainless steel bearing support frame, raw water delivery pump, automatic backwash valve manifold, online acid-base chemical cleaning dosing system, front-end security liquid filter and PLC intelligent touch control cabinet. After being filtered and purified by ultrafiltration membranes, raw water can fully meet the inlet water requirements of reverse osmosis, nanofiltration and other advanced desalination equipment, protecting the service life of high-cost desalination membranes. All finished filtration equipment will pass strict air tightness inspection and 72-hour continuous full-load aging test before delivery, avoiding unexpected shutdown failures during long-term on-site operation.
We develop diversified water treatment filtration products to match differentiated project demands. Integrated filtration and desalination demands can be satisfied with Ultrafiltration Equipment Reverse Osmosis Combined Water Treatment System to finish overall water purification work with one single device. For projects with special requirements on water flow, equipment layout, workshop space and special water quality conditions, we provide drawing customization and processing service through Ultrafiltration Equipment Company Providing Custom Water Treatment. Clients who need matched ultrafiltration and reverse osmosis supporting facilities can choose integrated finished products supplied by Professional Manufacturer of Ultrafiltration and Reverse Osmosis Equipment. Ordinary factory circulating cooling water and production domestic water treatment adopt cost-effective standard Ultrafiltration Membrane Water Treatment Equipment for Industrial Use. Large water volume industrial purification scenarios with high treatment efficiency requirements are equipped with High Efficient Hollow Fiber Ultrafiltration Equipment to lift the overall processing capacity of the water station system.
Standard frames and pipelines of the filtration system are made of SUS304 stainless steel; SUS316L stainless steel is configured for brine, acidic wastewater and alkaline wastewater treatment projects to prevent electrochemical corrosion and prolong equipment service life. The control system supports local touch screen operation, with optional remote online real-time monitoring function for centralized management. Our company supplies in-stock standard devices, non-standard customized production, OEM supporting processing and complete CE certification documents, helping overseas customers smoothly complete customs declaration clearance and project acceptance procedures.
Our water treatment filtration equipment runs with pressure-driven cross-flow ultrafiltration mode. The built-in PLC intelligent program automatically switches three working modes: normal water production filtration, automatic backwashing cleaning and regular chemical deep cleaning.
Original industrial wastewater or raw water firstly removes large particle sediment and impurities through the front-end liquid filter, then is delivered into the inner cavity of ultrafiltration membrane filaments under the pressure of the feed pump. With fixed membrane pore size ranging from 0.01μm to 0.1μm, water molecules and tiny soluble ions penetrate the membrane wall to form qualified clean water and flow into the subsequent desalination unit. Suspended particles, bacteria, algae and organic pollutants are intercepted on the outer surface of the membrane. High-speed cross-flow water continuously scours the membrane surface to slow down the accumulation speed of pollutant filter cake and maintain stable water production flux in long-period continuous operation.
As intercepted contaminants keep accumulating, the pressure difference between the inlet and outlet of membrane modules will rise gradually. Once the pressure difference hits the preset alarm threshold value, the system will automatically switch the pipeline valve group. Clean produced water flows reversely to wash off loose dirt attached to membrane surfaces, and the dirt is discharged out of the equipment together with concentrated wastewater. The whole backwashing process only lasts 3–8 minutes without causing long-time shutdown of the whole water treatment system.
Physical backwashing cannot completely eliminate stubborn biological slime and organic dirt attached inside membrane pores. The matched dosing system prepares dilute acid and alkaline cleaning solution for circulating immersion cleaning, restores the original flux of ultrafiltration membranes, and keeps the water treatment filtration equipment operating at high efficiency stably.

Q1: What core advantages does membrane-based water treatment filtration equipment have over traditional sand filter equipment?
A: Membrane filtration adopts fixed pore physical interception, so effluent quality will not fluctuate with raw water turbidity changes. This kind of equipment occupies less space with high automation degree, greatly saving manual labor cost, and the later maintenance workload is far lower than traditional filtering facilities.
Q2: Can water flow, pipeline material grade and automatic running programs be customized according to customers’ actual water quality test reports?
A: Yes. Our technical team will match membrane models, pump power and pipeline materials based on users’ water quality data, optimize backwashing and chemical cleaning logic, and formulate targeted non-standard design solutions.
Q3: What are the delivery cycles for standard spot filtration equipment and customized modified equipment respectively?
A: Conventional standard devices represented by 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 modification scope and processing difficulty.
Q4: What pre-filter devices should be installed at the water inlet of water treatment filtration equipment?
A: It is recommended to install coarse filter + multi-media filter + security liquid filter at the front end to intercept large particle sediment, prevent physical scratch damage to membrane filaments, and lower the overall pollution burden of ultrafiltration modules.
Q5: Which components of water treatment filtration equipment are covered by the factory official warranty scope?
A: Stainless steel frame, water pumps, valve bodies, PLC control cabinet and testing instruments enjoy a 1-year global factory warranty. Ultrafiltration membrane elements belong to consumable parts and are not included within the warranty coverage.
Q6: Is parallel operation of multiple sets of water treatment filtration equipment allowed to expand the overall water processing capacity of water stations?
A: Parallel connection operation is fully supported. Multiple filtration units are connected to the main water pipeline with unified central automatic control, convenient for customers to expand water treatment capacity in batches along with factory production scale expansion.
