Read： 850 Time：20months ago Source：Transform the World with Simplicity

Candle filter is widely used in industrial, pharmaceutical and biochemical fields of a filter equipment. The principle is to use the filter element "candle"-shaped structure to filter the liquid to be filtered, so as to remove impurities or microorganisms and other unwanted components. Candle filter can be used for liquid-solid two-phase separation, liquid-liquid phase separation and even gas-liquid separation and other business needs to deal with materials. The filtering principle of the

candle filter is directly related to the structure of the filter element. The filter element is usually made of ceramic, glass fiber, polyamide, polyether sulfone and other materials, and sometimes different materials are used to make composite filter elements. The nature of these materials is different, and the filtration accuracy that can be achieved is also different. However, regardless of the material of the filter element, its structure is "candle" shape, that is, the center is barrel-shaped, the surface is film-shaped, and there are a large number of openings. The liquid needs to enter the center of the candle core through the filter element hole. The liquid passing through the filter element gathers on the inner wall of the barrel and is discharged through the filter. The filtered impurity particles form a film on the filter element, which can cut the impurities, and a new filter membrane is formed around the surface of the filter element. This ensures the filtering effect and efficiency of the filter.

candle filter can not only remove microorganisms, particles, colloids and other components that need to be filtered, but also can separate water, volatile oil or fat and other components with different physical and chemical characteristics. Therefore, in industry, it can be used for the treatment of wastewater, ponds, fluids and other liquids; in the field of medicine or biology, it can filter and separate different kinds of materials such as blood, cell culture medium, pharmaceutical intermediates, biochemical preparations, and even in food and beverage processing. Compared with other filtration equipment,

candle filter has a unique filtration principle and a variety of different applications. Compared with other filtering equipment, the advantages of candle filter are as follows:

1. high filtration efficiency, can quickly separate impurities in the filtrate.

2. The filter material is durable and has a long service life.

3. The filter is easy to maintain and the maintenance cost is low.

4 is widely used and can deal with different filtration needs in different fields.

candle filter is a kind of filter equipment with excellent performance and wide application, which has an irreplaceable position in the fields of industry, medicine and biochemistry. Through the understanding of the principle of candle filtration, we can make better use of this equipment and improve the efficiency and output of processing materials. If you need to use or buy a candle filter, it is recommended that you understand the type and purpose of the filter in detail, and choose according to actual needs, in order to better exert the effect of the filter.
