Ultrafiltration UF is a widely adopted low-pressure membrane separation technology for industrial water purification and wastewater recycling.

Product Description
Ultrafiltration UF refers to the pressure-driven membrane separation technology that intercepts substances according to molecular weight cutoff, and also represents the complete set of membrane filtration equipment based on this principle. A full UF system generally includes membrane modules, feed pumps, backwashing pipelines, chemical cleaning assemblies and intelligent control cabinets. Different from nanofiltration and reverse osmosis, Ultrafiltration UF works under low operating pressure, focusing on removing particulate pollutants rather than dissolved salts.
Project owners can select standardized frame-type units, or purchase pre-assembled Ultrafiltration Machine for All Industrial Water Treatment Projects to cut on-site installation cycles. For heavily contaminated wastewater that contains plenty of sediment and organic pollutants, customers can configure supporting Tubular Ultrafiltration Membrane for Heavy Polluted Water Treatment as front-end filtration to reduce pollution load of main UF modules. The complete Ultrafiltration UF system supports continuous 24-hour unattended running, and can be applied in pure water pretreatment, production wastewater recovery, municipal reclaimed water treatment and circulating water raw water purification for food, chemical, pharmaceutical and mining industries.
Working Principle
Ultrafiltration UF relies on physical interception by membrane micropores to realize separation under low cross-flow pressure. Raw water flows along the surface of membrane components. Water molecules and tiny soluble ions pass through membrane pores to form clean permeate water. Substances with larger size than membrane pore channels, including suspended particles, colloids, bacteria and macromolecular organics, are trapped on the membrane surface.
Continuous cross-flow water scours the membrane surface to reduce pollutant accumulation. The automatic control system performs regular backwashing to flush intercepted contaminants. When flux declines due to persistent fouling, online chemical enhanced cleaning will be triggered to recover membrane permeability. Users can adopt independent Ultrafiltration UF equipment, or choose integrated Ultrafiltration Machine for All Industrial Water Treatment Projects to simplify engineering layout. For complex wastewater with high suspended solid content, collocation with Tubular Ultrafiltration Membrane for Heavy Polluted Water Treatment achieves staged purification, prevents massive particles from directly impacting membrane surfaces and extends the service life of UF membrane elements. Compared with traditional sedimentation and medium filtration processes, Ultrafiltration UF delivers steady effluent without excessive flocculant dosing.

FAQ
Q1: What pollutants can standard Ultrafiltration UF effectively remove?
A1: Ultrafiltration UF can intercept suspended solids, colloids, bacteria, algae and macromolecular organics. It cannot remove dissolved small-molecule salts, so it is usually used together with reverse osmosis systems for desalination requirements.
Q2: Can Ultrafiltration UF be assembled into integrated skid-mounted complete machines?
A2: Yes. We provide finished Ultrafiltration Machine for All Industrial Water Treatment Projects, pre-installed and tested in factory for fast on-site commissioning.
Q3: How to control membrane fouling during long-term continuous running of Ultrafiltration UF?
A3: The system adopts cross-flow scouring, regular automatic backwashing and periodic online chemical cleaning to slow down pollutant deposition on membrane surfaces.
Q4: Is it feasible to use Ultrafiltration UF with tubular membrane components to treat heavy polluted wastewater?
A4: Definitely. It can cooperate with Tubular Ultrafiltration Membrane for Heavy Polluted Water Treatment to build graded filtration processes for wastewater with high suspended solid content.
Q5: What is the typical operating pressure range of Ultrafiltration UF equipment?
A5: Normal working pressure is maintained between 0.1 MPa and 0.3 MPa. Low-pressure operation reduces power consumption and slows membrane aging.
