1、 Working principle of ultrafiltration equipment:

Ultrafiltration is a membrane separation process that uses sieving as the separation principle and pressure as the driving force. The filtration accuracy is in the range of 0.005-0.01 μ m, and it can effectively remove particles, colloids, bacteria, heat sources, and high molecular weight organic substances from water. It can be widely used for the separation, concentration, and purification of substances. The ultrafiltration process has no phase transformation and operates at room temperature, making it particularly suitable for the separation of thermosensitive substances. It has good temperature resistance, acid and alkali resistance, and oxidation resistance, and can be used continuously for a long time below 60 ℃ and pH 2-11.

2、 Classification of ultrafiltration membranes:

Ultrafiltration membranes can be divided into various structures according to their structural types, such as plate frame (plate type), hollow fiber type, nano membrane surface ultrafiltration membrane, tube type, roll type, etc. Among them, hollow fiber ultrafiltration membrane is a mature and advanced form of ultrafiltration technology. Hollow fiber has an outer diameter of 0.4-2.0mm and an inner diameter of 0.3-1.4mm. The wall of the hollow fiber tube is covered with micropores, and the pore size is expressed as the molecular weight that can intercept substances. The intercepted molecular weight can reach several thousand to several hundred thousand. The raw water flows under pressure outside or inside the hollow fibers, forming external and internal pressure hollow ultrafiltration membranes, respectively. Ultrafiltration is a dynamic filtration process, in which intercepted substances can be removed with concentrated solution without blocking the membrane surface, and can operate continuously for a long time.

4、 Early industrial ultrafiltration was applied to wastewater and sewage treatment. Over the past thirty years, with the development of ultrafiltration technology, the application fields of ultrafiltration membrane technology have become very wide, mainly including drinking water, food industry, beverage industry, dairy industry, biological fermentation, biomedicine, pharmaceutical and chemical industry, biological preparations, traditional Chinese medicine preparations, clinical medicine, printing and dyeing wastewater, food industry wastewater treatment, resource recovery, and environmental engineering, etc.

3、 Advantages of ultrafiltration equipment:

A、 The ultrafiltration membrane components adopt products from World Membrane Corporation, ensuring that customers receive high-quality organic membrane components, thereby ensuring retention performance and membrane flux.

B、 The system has a high recovery rate and produces high-quality products, which can achieve efficient separation, purification, and high fold concentration of materials.

C、 The processing process has no phase change and has no adverse effects on the composition of the material. The separation, purification, and concentration processes are always at room temperature, making it particularly suitable for the treatment of thermosensitive substances. This avoids the disadvantage of high temperature damaging bioactive substances and effectively preserves the bioactive substances and nutrients in the raw material system.

D、 The system has low energy consumption, short production cycle, and lower operating costs compared to traditional process equipment. It can effectively reduce production costs and improve the economic efficiency of enterprises.

E、 The system has advanced process design, high integration degree, compact structure, small footprint, easy operation and maintenance, and low labor intensity for workers.

F、 The system is made of sanitary grade control valves, and the site is clean and hygienic, meeting the requirements of GMP or FDA production standards. G. The control system can be personalized according to users' specific usage requirements, combined with advanced control software, to centrally monitor important process operating parameters online on site, avoiding manual errors and ensuring long-term stable operation of the system from multiple perspectives.
