Column-type Ultrafiltration Membrane Assembly

    I. What is column-type ultrafiltration membrane assembly?

Column-type ultrafiltration membrane assembly is a water treatment technology that uses ultrafiltration membrane to separate suspended matter, bacteria, viruses and macromolecules in water. Unlike curtain-type ultrafiltration membrane modules, column-type ultrafiltration membrane modules are usually composed of multiple membrane tubes (or membrane columns) with supporting structures inside, and water flows inside the membrane tubes for filtration;

● It can be sterilized by high temperature steam, radiation and ethylene oxide and can be sterilized repeatedly.

    II. What are the characteristics of curtain-type ultrafiltration membrane assembly?

● High mechanical strength and toughness, very good dimensional stability, and excellent pore size control performance.

● High surface hydrophilicity and good anti-pollution ability.

● ph (1-14), short-term heat resistance 220 degrees, long-term heat resistance 200 degrees.

● Strong tolerance to active chlorine, it can withstand 5000ppm for a long time.

● Excellent resistance to hot water and wide range of chemical agents.

● Low extractable content ensures safety and harmlessness.

● High strength, acid and alkali resistance, bacterial corrosion resistance and good temperature resistance.

● The surface is non-polar and has no adsorption effect.

● Large specific surface area and high packing density per unit volume.

● Internal pressure type, low transmembrane pressure, good antibacterial performance, and a molecular weight cutoff of 50,000 Daltons.

● It can achieve cross-flow filtration, with smooth backwash flow channel and good flushing effect.

    III. What are the application fields of curtain-type ultrafiltration membrane assembly?

· Treatment of industrial wastewater: It is especially suitable for chemical, pharmaceutical and other industries, and can be used to treat wastewater with high turbidity and complex water quality, reduce pollutant emissions and meet environmental protection standards.

· Food and beverage industry: It is used to purify raw water during the production process, remove microorganisms and harmful substances in the water, and ensure food safety and quality.

· Water reuse: In industrial parks or large facilities, by deeply treating wastewater, it can achieve reuse of water, thus saving water resources and reducing production costs.
