1、 Range of filtering accuracy
Generally speaking, the filtration accuracy range of precision filters can range from micrometer level (such as 1 μ m, 0.2 μ m) to sub micrometer level, and even nanometer level. This high-precision filtering capability enables it to effectively remove particles as small as sub micron, including bacteria, viruses, and other microorganisms.
2、 Factors affecting filtration accuracy
Filter cartridge material: Filter cartridges made of different materials have differences in filtration accuracy. For example, ceramic filter cartridges typically achieve higher filtration accuracy, while some synthetic fiber filter cartridges may perform well in specific applications.
Aperture size: The smaller the aperture, the higher the filtration accuracy of the precision filter. However, a too small aperture can also increase pressure loss and may have an impact on the lifespan of the filter element.
Number of filter layers: Increasing the number of filter layers can improve filtration accuracy, but it also increases the complexity and maintenance difficulty of the filter.
3、 Specific accuracy requirements
For different application scenarios, the precision requirements for the filter mesh accuracy of precision filters also vary. For example:
In the field of water treatment, precision filters are commonly used to remove suspended solids, colloids, bacteria, and other impurities from water. According to different water quality requirements, the filtration accuracy may be between 0.1 μ m and 100 μ m.
In the fields of medicine and biotechnology, higher requirements are placed on filtration accuracy to ensure product purity and safety. Precision filters in these fields may adopt nanometer level filtration accuracy.
In the food and beverage industry, precision filters are used to ensure the clarity and taste of products. The filtration accuracy is usually determined based on the specific requirements of the product and regulatory standards.
The precision requirements for the filter mesh of precision filters are a complex issue that needs to be determined based on specific application scenarios and requirements. When selecting and using precision filters, it is necessary to fully understand their filtration accuracy, material, pore size and other parameters, and make reasonable choices and configurations based on actual situations. At the same time, it is necessary to regularly maintain and upkeep the filter to ensure its long-term stable operation and meet accuracy requirements.
