The microporous precision filter is a cutting - edge filtration device engineered to meet the most stringent filtration requirements across a wide spectrum of industries. Leveraging advanced technology and high - grade materials, it provides exceptional performance in separating minute particles and bacteria from liquids and gases.

I. Product Introduction

This microporous precision filter represents a revolutionary development in the field of filtration, both at home and abroad. Its primary function is to efficiently eliminate particles and bacteria larger than 0.1μm from fluid media, whether it's liquid or gaseous. The construction of this filter incorporates a combination of top - tier materials, guaranteeing its durability and consistent, reliable performance over an extended period.

Structure

1. Filter Core Assembly

The filter core lies at the core of the filtration system. It is composed of folded microporous membrane cartridges, which are available in a variety of materials such as polypropylene, polytetrafluoroethylene, and acetate fiber. These cartridges are designed with a high - surface - area - to - volume ratio, enabling them to trap fine particles with remarkable efficiency. The number of cartridges can be customized according to the specific filtration capacity needs of different applications. Options range from a single - core configuration for smaller - scale operations to multi - core setups like 1 - core, 3 - cores, 5 - cores, 7 - cores, 9 - cores, 11 - cores, 13 - cores, or 15 - cores for higher - volume filtration requirements. Additionally, the length of the folded cartridges can be adjusted to suit various filtration scenarios, with standard lengths of 10, 20, 30, and 40 inches.

2. Stainless Steel Housing

The outer housing of the filter is crafted from premium - grade stainless steel, typically 304 or 316L. This choice of material ensures that the housing is not only robust and capable of withstanding high - pressure operations but also highly resistant to corrosion, which is crucial for maintaining the integrity of the filter in harsh operating environments. Both the inner and outer surfaces of the housing are precision - polished to a mirror - like finish, with a roughness Ra≤0.28μm. This meticulous polishing process eliminates any potential crevices or rough areas where dirt, contaminants, or bacteria could accumulate, thereby ensuring strict compliance with “FDA” and “GMP” standards. The housing is ingeniously designed to be divided into two parts, which are connected by either quick - fit clamps or quick - open ring - head bolts. This design feature allows for easy and rapid access to the filter cartridges, facilitating their replacement or cleaning, which in turn helps to minimize downtime during maintenance operations.

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. This even distribution is achieved through a carefully designed inlet manifold system, which ensures that the fluid flows uniformly across the surface area of the cartridges. The fluid then begins to pass through the microporous membranes of the cartridges.

• Particle Interception

The pores in the microporous membranes are precisely 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 of the membrane or within the pores themselves. This process is based on the principle of physical sieving, where the size of the pores acts as a barrier to the passage of larger particles. The purified fluid, now free from the targeted contaminants, then exits the filter through the outlet, ready for further use or processing in the downstream operations.

2. Backwash and Maintenance

• Backwash Trigger

As the filtration process progresses, impurities gradually accumulate on the surface of the filter cartridges. This accumulation increases the resistance to fluid flow, causing the pressure difference between the inlet and outlet of the filter to rise. When this pressure difference reaches a pre - set value (which is typically determined based on the specific requirements of the application and the characteristics of the fluid being filtered), or when a certain operating time has elapsed (as determined by a time - based control system), the backwash process is automatically initiated.

• Backwash Operation

During the backwash process, 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 is directed against the normal flow direction of the fluid during filtration. The high - velocity reverse flow effectively flushes away the accumulated impurities from the surface of the filter cartridges. The backwash fluid, now laden with the removed impurities, is then discharged through a separate outlet. This process helps to restore the permeability of the filter cartridges and maintain the efficient operation of the filter.

• Filter Cartridge Replacement

Despite regular backwashing, over time, the filter cartridges may experience wear and tear or become clogged to an extent where effective cleaning is no longer possible. When this occurs, the cartridges can be easily removed and replaced with new ones. The quick - fit connection design of the cartridges, which is facilitated by the use of specialized connectors or fittings, allows for rapid replacement. This not only minimizes the downtime associated with cartridge replacement but also ensures that the continuous operation of the filtration system is disrupted as little as possible.

III. Product Features

1. High Filtration Precision

This microporous precision filter is capable of achieving an extremely high level of filtration precision, with the ability to filter particles and bacteria as small as 0.1μm. This high - precision filtration ensures that the filtered fluid reaches an exceptionally high level of purity. As a result, it is particularly well - suited for applications where even the slightest presence of impurities can have significant consequences, such as in the pharmaceutical, electronics, and high - end food and beverage industries. In the pharmaceutical industry, for example, the removal of bacteria and fine particles from drug formulations is critical to ensure the safety and efficacy of the final product.

2. Fast Filtration Speed

The unique design of the microporous membranes and the optimized internal flow path within the filter enable a high - volume throughput of fluid while maintaining the integrity of the filtration process. The membranes are engineered to have a high porosity and a large effective filtration area, which allows for a rapid flow of fluid through the filter. At the same time, the internal geometry of the filter housing and the arrangement of the cartridges are designed to minimize flow resistance and ensure a smooth and efficient flow of the fluid. This combination of factors results in a fast filtration speed, which means that large quantities of fluid can be filtered in a relatively short time. This is highly beneficial in industrial processes where high productivity is a key requirement.

3. Low Adsorption

The filter media used in the cartridges have been carefully selected to have minimal adsorption properties. This means that they do not absorb valuable components or chemicals from the fluid being filtered. In applications such as the production of pharmaceuticals and fine chemicals, where the composition and purity of the fluid are of utmost importance, this low - adsorption feature is crucial. For instance, in the manufacturing of certain drugs, any absorption of active ingredients by the filter media could lead to a loss of product quality and efficacy.

4. No Media Shedding

Thanks to the high - quality construction of the filter cartridges, there is no shedding of filter media during the filtration process. The cartridges are assembled using advanced manufacturing techniques and high - strength materials, which ensure that the filter media remain firmly in place. This prevents any secondary contamination of the filtered fluid by loose particles or fibers from the filter media. As a result, the filter provides a reliable and consistent filtration result, which is essential for applications where the quality of the filtered fluid must be maintained at a high level.
