Ultrafiltration working principle:
Ultrafiltration (ultrafiltration) is a pressure driven membrane separation process based on sieve separation principle. The filtration accuracy
is within the range of 0.005-0.01 m, which can effectively remove particles, colloid, bacteria, heat source and polymer organic substances
in the water.It can be widely used in material separation, concentration and purification.Ultrafiltration process without phase
transformation, operating at room temperature, the separation of heat-sensitive substances is particularly suitable, and has good
temperature resistance, acid and alkali resistance and oxidation resistance, can be used under 60℃, pH of 2-11 for a long time continuous.
Classification of ultrafiltration membrane:Ultrafiltration membrane is divided into plate-frame type (plate type), hollow fiber type, tube type, roll type and other structures.Hollow
fiber ultrafiltration membrane is the most mature and advanced ultrafiltration technology.The outer diameter of hollow fiber is 0.4-2.0mm
, and the inner diameter is 0.3-1.4mm. The hollow fiber tube wall is full of micropores, and the pore size is expressed by the molecular
weight of the interception material, which can reach several thousand to several hundred thousand.The raw water flows under pressure
in the outer or inner cavity of the hollow fiber to form the outer and inner pressure hollow ultrafiltration membranes respectively.
Ultrafiltration is a dynamic filtration process in which the trapped material can be removed with the concentrated solution without
blocking the membrane surface and can run continuously for a long time.
Early industrial ultrafiltration was used in wastewater and sewage treatment.For over 30 years, with the development of ultrafiltration
technology, the field of the application of ultrafiltration membrane technology has now is very wide, mainly including the food industry,
beverage industry, dairy industry, fermentation, biological medicine, medicine, chemical, biological agents, Chinese medicine, clinical
medicine, printing and dyeing wastewater, food industry wastewater treatment, recycling and environmental engineering, etc.

☆Ultrafiltration membrane elements are manufactured by the world famous membrane company, which ensures that customers get
the best quality organic membrane elements in the world, thus ensuring the interception performance and membrane flux.
☆The system has a high recovery rate and the products are of high quality.☆Process without phase transformation and composition of the material without any adverse effects, and in the process of separation,
purification, concentration remain the state of the normal temperature, especially suitable for the processing of heat sensitive material,
completely avoid the high temperature and the disadvantages of destruction of bioactive substances, effectively keep the bioactive
substances in raw material system and nutrients.
☆System energy consumption is low, production cycle is short, compared with the traditional process equipment, equipment
operating cost is low, can effectively reduce the production cost, improve the economic benefits of the enterprise.
☆The system has advanced technology design, high integration, compact structure, less floor space, easy operation and
maintenance, and low labor intensity.
☆The system is made of sanitary valve, which can meet the requirements of GMP or FDA.☆The control system can be customized according to the specific requirements of users. Combined with the advanced control
software, important process operation parameters can be centrally monitored online to avoid manual misoperation and ensure the
long-term stable operation of the system.

☆The filtration system should be sterilized periodically.Ultrafiltration membrane can retain bacteria, but it can not kill bacteria,
the interception rate is good ultrafiltration membrane can not ensure a long-term clean area not a bacteria, bacteria may multiply.Direct
impact through the water quality, such as some mineral water products in the translucent filamentous white flocculent mold group, mainly
caused by mold contamination system.Therefore, it is necessary to periodically sterilize the turnover environment and the filtration system
. The operation cycle of sterilization is determined by the quality of the raw water supplied. For urban common tap water, 7-10 days in
summer, 30-40 days in winter, 20-30 days in spring and autumn.When surface water is used as the source of supply, the sterilization
period is shorter.Sterilization drugs can be used 500 ~ 1000mg/L sodium hypochlorite solution or 1% hydrogen peroxide aqueous solution
circulating flow or soak for about half an hour.
☆As each ultrafiltration component is added with protective fluid before leaving the factory, the protective fluid in the component
should be thoroughly flushed before use. First, flush with low-pressure (0.1mpa) water supply for 1 hour, and then flush with
high-pressure (0.2mpa) water supply for 1 hour. When flushing with either low pressure or high pressure, all the water production and
discharge valves of the system should be opened.When using the produced water, check and make sure that the water does not contain
any fungicide.
☆ Ultrafiltration components should be handled lightly and protected. As ultrafiltration components are precision equipment, they
should be carefully used and installed.If the component is stopped, rinse it with clean water, add 0.5% formaldehyde solution to sterilize
and seal it.If the winter components should be treated with anti-freezing, otherwise the components may be scrapped.
