Trusted Ultrafiltration Equipment Factory for Industrial Water Treatment
As a professional ultrafiltration equipment factory with complete independent production capacity, Xinxiang Lifeierte Filter Corp., Ltd designs, produces and customizes full-series UF systems for global industrial water treatment projects. Serving as a full-range industrial liquid filter manufacturer integrating research, production and after-sales service, our product portfolio covers high-load Concentrated Ultrafiltration Membrane Equipment, high-precision Dual Stage Ultrafiltration Equipment, space-saving Compact Small Scale Ultrafiltration Membrane Equipment, and one-stop packaged Complete Ultrafiltration Equipment to satisfy customized demands from small businesses to large-scale industrial parks worldwide.

Our ultrafiltration equipment factory owns standardized production workshops, membrane testing laboratories, precision welding workshops and finished product debugging workshops, realizing full independent production of membrane assembly, stainless steel frame, pipeline layout, automatic control cabinet and supporting accessories. Different from trading companies, we can flexibly adjust equipment structure, water output, control logic and material configuration according to customers’ actual water quality data, site area and local industry standards.
Aiming at diversified working conditions on the global market, our factory has developed differentiated ultrafiltration products. For wastewater concentration, material separation and high-pollution sewage treatment, customers can select Concentrated Ultrafiltration Membrane Equipment, which optimizes the membrane module layout to improve pollutant bearing capacity and concentration multiple. For pharmaceutical purified water, electronic ultrapure water pretreatment with extremely high water quality requirements, our Dual Stage Ultrafiltration Equipment adopts two-stage graded interception to further remove tiny colloids and microorganisms and improve the safety of subsequent water making links. For small factories, laboratories, commercial water dispensers and limited installation space, the skid-mounted Compact Small Scale Ultrafiltration Membrane Equipment realizes integrated layout of all parts with small footprint and plug-and-play installation. For large municipal reclaimed water stations, chemical park centralized water supply and factory overall water renovation projects, the pre-assembled and fully tested Complete Ultrafiltration Equipment reduces on-site construction difficulty and shortens the whole project delivery cycle.
All ultrafiltration membrane elements adopted by our factory are modified anti-fouling PVDF material with strong acid, alkali and oxidation resistance. The equipment frame is made of standard 304 stainless steel, and 316L stainless steel, PVC-U or other anti-corrosion materials can be customized for special corrosive water bodies. The PLC automatic control system independently programmed by our technical team supports differential pressure monitoring, automatic backwashing, timing chemical cleaning and remote operation linkage, realizing 24-hour unattended operation. As a professional ultrafiltration equipment factory, we provide whole-process services including scheme design, production, factory debugging, overseas shipment guidance and after-sales technical support for global partners.
All ultrafiltration devices manufactured by our factory adopt pressure-driven cross-flow filtration technology, which is divided into normal water production filtration and membrane cleaning regeneration two circulating working modes.
Raw water is boosted by the feed pump to the rated operating pressure of 1.0–3.6 bar and enters the inside of the ultrafiltration membrane component. With the physical screening effect of 0.01~0.1μm micropores on the membrane wall, water molecules and small molecular soluble salts pass through the membrane to form qualified produced water for production use. Suspended solids, colloids, bacteria, algae and macromolecular organic pollutants are intercepted on the outer surface of the hollow fiber membrane. A part of water flows at high speed along the membrane surface to form cross-flow concentrated water, which continuously washes away most pollutants and avoids the formation of compact filter cake on the membrane surface.
After long-term continuous operation, a small amount of pollutants will accumulate on the membrane surface to cause flux attenuation. The factory’s built-in control program automatically triggers two cleaning modes: regular backwashing uses clean produced water for reverse flushing to peel off loose surface dirt; periodic CIP chemical cleaning uses matched chemical agents to dissolve biological slime and organic fouling, restore the original flux of the membrane module, and guarantee the long-term stable water production efficiency of the equipment.

Q1: What advantages does buying ultrafiltration equipment directly from the factory have compared with purchasing from distributors?
A: Direct factory sales remove intermediate markup, with more competitive prices; meanwhile, the factory can carry out targeted non-standard customization according to actual working conditions, and the after-sales response speed is faster with professional technical support team.
Q2: Can your ultrafiltration equipment factory provide overseas installation guidance and operation training documents?
A: Yes. We provide English operation manuals, video tutorials, and engineers can conduct remote online guidance for equipment installation, commissioning and daily operation training.
Q3: How long is the production cycle for a set of customized ultrafiltration equipment in your factory?
A: Conventional standard equipment delivery cycle is 7–10 working days; large-scale customized integrated ultrafiltration equipment is 15–25 working days, which can be negotiated according to the order quantity.
Q4: Can the ultrafiltration equipment produced by your factory be matched with existing old water treatment systems of customers?
A: Our technical team can dock the parameters of the original system according to the customer’s equipment drawings and operation data, modify the interface and control signal to realize seamless matching access.
Q5: What after-sales warranty policy does your ultrafiltration equipment factory implement?
A: The whole machine has a one-year warranty (excluding consumable membrane elements); lifetime cost price supply of spare parts and permanent free technical consulting service.
Q6: Is the ultrafiltration equipment produced by the factory suitable for high-temperature and strong acid wastewater treatment environments?
A: Conventional standard equipment is suitable for normal temperature and neutral water quality; we can select high-temperature resistant membrane materials and anti-corrosion pipeline materials to produce special ultrafiltration equipment for high temperature and strong acid working conditions.
