Large flow ultrafiltration equipment

Ultrafiltration (UF) is a membrane separation technology that can purify and separate solutions. An UF membrane system uses ultrafiltration membrane filaments as the filtration medium and the pressure difference across the membrane as the driving force for solution separation. The UF membrane allows only the solvent (such as water molecules), inorganic salts, and small organic molecules in the solution to pass through, while retaining macromolecules such as suspended matter, colloids, proteins, and microorganisms, thereby achieving the purpose of purification or separation.

Working Principle

Ultrafiltration is a membrane separation process based on the principle of sieving and driven by pressure. With a filtration accuracy range of 0.005-0.01μm, it effectively removes particles, colloids, bacteria, heat sources, and high-molecular-weight organic matter from water. It is widely used for the separation, concentration, and purification of substances. The ultrafiltration process does not involve phase transformation and operates at room temperature, making it particularly suitable for separating heat-sensitive substances. It also exhibits excellent resistance to heat, acids, alkalis, and oxidation, and can operate continuously for extended periods at temperatures below 60°C and a pH range of 2-11.

Applications of Ultrafiltration Technology

In the early days, industrial ultrafiltration was used for wastewater and sewage treatment. Over the past 30 years, with the development of ultrafiltration technology, ultrafiltration membrane technology has expanded to a wide range of applications, including in the food, beverage, and dairy industries, biofermentation, biopharmaceuticals, pharmaceutical chemicals, biological preparations, traditional Chinese medicine preparations, clinical medicine, printing and dyeing wastewater, food industry wastewater treatment, resource recovery, and environmental engineering.
