The duplex microporous precision filter is a state - of - the - art filtration solution, designed to meet the most demanding filtration requirements across various industries. With its advanced technology and high - quality construction, it offers unrivaled performance in filtering out fine particles and bacteria from liquids and gases.

I. Product Introduction

The duplex microporous precision filter is a novel filtration device developed both domestically and internationally. It is engineered to effectively remove particles and bacteria larger than 0.1μm from liquids and gases. This filter is constructed with a combination of high - quality materials, ensuring durability and reliable performance.

Structure

1. Filter Core Assembly: The filter core is the heart of the system. It consists of folded microporous membrane cartridges, available in materials such as polypropylene, polytetrafluoroethylene, and acetate fiber. These cartridges are highly efficient in trapping fine particles. The number of cartridges can be customized, with options ranging from single - core to multi - core configurations like 1 - core, 3 - cores, 5 - cores, 7 - cores, 9 - cores, 11 - cores, 13 - cores, or 15 - cores, depending on the filtration capacity needed. The length of the folded cartridges is also variable, with standard sizes of 10, 20, 30, and 40 inches.

2. Stainless Steel Housing: The outer housing is made of premium stainless steel, typically 304 or 316L. The housing is not only robust but also resistant to corrosion, ensuring a long - service life. Both the inner and outer surfaces of the housing are precision - polished to a mirror - like finish (with a roughness Ra≤0.28μm), eliminating any potential areas for dirt or bacteria to accumulate, thus meeting strict “FDA” and “GMP” compliance standards. The housing is divided into two parts, which are connected by quick - fit clamps or quick - open ring - head bolts. This design allows for easy and rapid replacement or cleaning of the filter cartridges.

II. Working Principle

1. Filtration Process

• Fluid Inflow: When the fluid (either liquid or gas) enters the filter under a certain pressure, it is evenly distributed around the filter cartridges. The fluid then passes through the microporous membranes of the cartridges.

• Particle Interception: The pores in the microporous membranes are sized to be smaller than the particles and bacteria that need to be filtered out. As the fluid permeates through the membranes, particles and bacteria larger than 0.1μm are physically trapped on the surface or within the pores of the membrane. The purified fluid then exits the filter through the outlet, ready for further use or processing.

2. Backwash and Maintenance

• Backwash Trigger: As the filtration process continues, impurities gradually accumulate on the filter cartridges, increasing the resistance to flow and causing the pressure difference between the inlet and outlet to rise. When this pressure difference reaches a pre - set value (usually within a specific range depending on the application), or when a certain operating time has elapsed (e.g., based on a time - based control system), the backwash process is initiated.

• Backwash Operation: During the backwash, a reverse flow of clean fluid (such as clean water for liquid - filtering applications or compressed air for gas - filtering applications) is introduced through a dedicated backwash inlet. This reverse flow flushes away the accumulated impurities from the filter cartridges. The backwash fluid, along with the removed impurities, is then discharged through a separate outlet.

• Filter Cartridge Replacement: Over time, despite regular backwashing, the filter cartridges may experience wear and tear or become clogged beyond effective cleaning. When this occurs, the cartridges can be easily removed and replaced with new ones. The quick - fit connection design of the cartridges allows for rapid replacement, minimizing downtime and ensuring continuous filtration operations.

III. Product Features

1. High Filtration Precision: Capable of filtering particles and bacteria as small as 0.1μm, ensuring a high level of purity in the filtered fluid. This makes it ideal for applications where even the smallest impurities can cause significant problems, such as in the pharmaceutical, electronics, and high - end food and beverage industries.

2. Fast Filtration Speed: The unique design of the microporous membranes and the optimized flow path within the filter enable a high - volume throughput of fluid while maintaining the filtration efficiency. This means that large quantities of fluid can be filtered in a relatively short time, increasing productivity in industrial processes.

3. Low Adsorption: The filter media used in the cartridges have minimal adsorption properties, which means that they do not absorb valuable components or chemicals from the fluid being filtered. This is crucial in applications where the integrity of the fluid composition needs to be preserved, such as in the production of pharmaceuticals and fine chemicals.

4. No Media Shedding: The high - quality construction of the filter cartridges ensures that there is no shedding of filter media during the filtration process. This prevents any secondary contamination of the filtered fluid, providing a reliable and consistent filtration result.

5. Acid and Alkali Corrosion Resistance: Made from corrosion - resistant materials like stainless steel 304 and 316L, the filter can withstand exposure to a wide range of acidic and alkaline fluids without degradation. This makes it suitable for use in harsh chemical environments, such as in chemical processing plants and industrial wastewater treatment facilities.

6. Convenient Operation: The filter is designed for ease of use. The quick - fit connections for the filter cartridges and the simple control system for the backwash process allow for easy maintenance and operation. Even non - specialized personnel can perform routine maintenance tasks, reducing the need for highly trained technicians and minimizing operational costs.

7. Compact Design: Despite its high - performance capabilities, the duplex microporous precision filter has a relatively compact footprint. This makes it suitable for installation in areas with limited space, such as in small - scale industrial plants, laboratories, or on - site water treatment facilities.

VI. FAQ

1. How do I choose the right filtration precision for my application?

The choice of filtration precision depends on the nature of the fluid being filtered and the specific requirements of your application. For applications where even the smallest particles can cause problems, such as in the pharmaceutical or electronics industries, a higher precision (e.g., 0.1μm or 0.22μm) may be required. For general industrial applications or less sensitive processes, a lower precision (e.g., 1μm - 10μm) may be sufficient. It is recommended to consult with our technical team, who can assess your specific needs and provide expert advice.
