Small and medium-sized ultrafiltration equipment is widely used in water treatment projects. Ultrafiltration technology is playing an increasingly important role in fields such as reverse osmosis pretreatment, drinking water treatment, and reclaimed water reuse. Ultrafiltration technology plays a key role in the sterilization and turbidity removal of alcoholic beverages, the removal of heat sources from drugs, and the concentration process of food and pharmaceuticals.
Small and medium-sized ultrafiltration equipmentWorking Principle:
Ultrafiltration is a membrane separation process that uses sieving as the separation principle and pressure as the driving force. The filtration accuracy is0.005-0.01μmWithin the scope, 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 also has good temperature resistance, acid and alkali resistance, and oxidation resistance, and can be used in60℃ following,pHfor2-11Long term continuous use under certain conditions.
Small and medium-sized ultrafiltration equipmentApplication of technology:
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 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.
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 type of ultrafiltration technologyzuiA mature and excellent form. Hollow fiber outer diameter0.4-2.0mm, inner diameter0.3-1.4mmThe hollow fiber tube wall is covered with micropores, and the pore size is expressed in terms of the molecular weight that can intercept substances, with a molecular weight interception of 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.
Small and medium-sized ultrafiltration equipmentAdvantages:
AThe control system can be personalized according to users' specific usage requirements, combined with excellent control software, to centrally monitor important process operation parameters online on site, avoid manual errors, and ensure long-term stable operation of the system from multiple perspectives
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 excellent 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 pipe valves, which are clean and hygienic on site, meeting the requirementsGMPorFDAProduction standard requirements.
