Column-type Ultrafiltration Membrane Module

    I. What is the Column-type Ultrafiltration Membrane Module?

The column-type ultrafiltration membrane module is a water treatment device that uses ultrafiltration membranes to separate suspended solids, bacteria, viruses, and macromolecular substances from water. Unlike curtain-type ultrafiltration membrane modules, a column-type module typically consists of multiple membrane tubes (or membrane columns) with internal support structures, and water flows through the membrane tubes for filtration.

    II. Features of Curtain-type Ultrafiltration Membrane Module

● Offers superior mechanical properties and toughness, excellent dimensional stability, and outstanding pore size control.

● Exhibits high surface hydrophilicity and good fouling resistance.

● Remains stable at pH 1–14 and withstands short-term temperatures up to 220°C and long-term temperatures up to 200°C.

● Exhibits strong active chlorine tolerance, withstanding 5,000 ppm for prolonged periods.

● Exhibits excellent hot-water resistance and broad chemical resistance.

● It can be sterilized by high-temperature steam, irradiation, and ethylene oxide (EO), and can be repeatedly sterilized.

● Features low extractables, ensuring safety and harmlessness.

● It offers high strength, acid and alkali resistance, bacterial corrosion resistance, and excellent heat resistance.

● It has a nonpolar surface and exhibits no adsorption.

● Offers a large specific surface area and high packing density per unit volume.

● Operating in internal-pressure mode, it provides low transmembrane pressure and excellent bacteriostatic performance, with a molecular weight cut-off (MWCO) of 50 kDa.

● Supports cross-flow filtration, with unobstructed backwash channels ensuring effective cleaning.

    III. The applications of Curtain-type Ultrafiltration Membrane Module

● Industrial waste liquid treatment: Particularly suitable for the chemical, pharmaceutical, and other industries; capable of treating waste liquid with high turbidity and complex water quality, reducing pollutant discharge and meeting environmental standards.

● Food and beverage industry: Used to purify process water during production, removing microorganisms and harmful substances to ensure the safety and quality.

            ● Water reuse: In industrial parks or large facilities, advanced waste liquid treatment enables water reuse, saving water resources and reducing production costs.
