Filtration Effect and Applications of Microporous Glass Fiber Membrane Filter

Microporous glass fiber membrane filter is one of the famous membrane filters, which has the advantages of high filtration precision, fast filtration speed, less adsorption, no medium shedding, no leakage, acid, and alkali corrosion resistance, easy operation, and so on. It can remove bacteria and particles from water and liquid in injection water and can be recoil when cleaning. Microporous glass fiber membrane filters have the advantages of a high flow rate, strong pollution absorption ability, and high efficiency, and can filter fine particles. Microporous glass fiber membrane filters are used for daily air pollution monitoring and special monitoring of solid pollutants, microorganisms, oil, and acid mist in the air.

Preparation for Operation

Before the installation of the filter, the filter element and shell should be thoroughly cleaned and sterilized. After applying a clean filter liquid as a lubricant to the “O” ring, insert the filter element carefully and vertically into the socket plate at the lower part of the filter. If the pump uses 226 interfaces, the two ears should be inserted into the chassis. After the filter “O” is replaced into the socket, rotate clockwise so that the two ears are stuck into the empty slot of the chassis. After the filter system has been rinsed, the whole filter system must also be thoroughly rinsed with clear water. When the whole filtration system is washed clean, it can be filtered.

Microporous glass fiber membrane filters are highly effective in various filtration applications due to their unique properties. Here’s an overview of their filtration effect:

  1. Fine Pore Structure:
    • Microporous glass fiber filters have a fine and uniform pore structure. This allows them to effectively capture particles of various sizes.
  2. High Porosity:
    • These filters have a high porosity, which means they can hold a significant amount of particles while maintaining good flow rates.
  3. High Retention Efficiency:
    • Microporous glass fiber filters are designed to retain a wide range of particle sizes, from fine particulates to larger contaminants. This makes them versatile for different filtration needs.
  4. Chemical Compatibility:
    • They are chemically inert and compatible with a wide range of solvents and chemicals. This makes them suitable for a variety of applications, including aggressive chemical filtration.
  5. Low Extractables:
    • These filters have low levels of extractables, meaning they release minimal substances into the filtrate, ensuring that the filtered solution remains uncontaminated.
  6. High Temperature Resistance:
    • Microporous glass fiber filters can withstand high temperatures, making them suitable for applications that require filtration at elevated temperatures.
  7. Sterilizability:
    • Some microporous glass fiber filters are designed for sterilization, making them ideal for critical applications in pharmaceuticals, biotechnology, and healthcare.
  8. Optical Clarity:
    • They provide excellent optical clarity, making them suitable for applications where clear filtrate is essential.
  9. Versatility:
    • Microporous glass fiber filters are used in a wide range of industries, including pharmaceuticals, biotechnology, environmental monitoring, food and beverage, and more.
  10. Air and Gas Filtration:
    • They can be used for air and gas filtration applications, including the removal of airborne particles and aerosols.
  11. Long Service Life:
    • Properly maintained, these filters can have a long service life, offering cost-effectiveness in filtration processes.
  12. Pre-filtration and Clarification:
    • They are often used as a pre-filter to remove larger particles before fine filtration, or for clarification purposes.

In summary, microporous glass fiber membrane filters offer high retention efficiency, chemical compatibility, and temperature resistance, making them highly effective in a wide range of filtration applications across various industries. Their versatility and reliability make them a popular choice for critical filtration processes.

The Applications of Microporous Glass Fiber Membrane Filters

In the applications of membrane separation technology, microporous glass fiber membrane filters are the most widely used. This kind of membrane filter is easy and convenient to use and has the advantages of high ventilatory capacity, high reject rate of particles, good thermal endurance, strong acid resistance, strong alkali resistance, organic solvent resistance, oxidizing agent resistance, aging resistance, non-stick, noninflammability, and excellent biocompatibility.

Moreover, the materials of microporous glass fiber membrane filters mainly include organic materials and inorganic materials. In consideration of the separation characteristics, the applied ranges of microporous glass fiber membrane filters are primarily retaining particles, bacteria, and other pollutants from gas chromatography and liquid chromatography, and thus achieve the aims of purification, separation, and concentration.

In terms of microfiltration, the retaining characteristics of membrane filters depend on the pore sizes. Generally, the pore sizes range from 0.1 μm to 1 μm, so the microporous glass fiber membrane filters can separate bacteria and suspended solids with large diameters.

Also, the microporous glass fiber membrane filters can be used for cartridge filtration and air sterilization. They are widely applied in the industries of scientific research, medicine & health, biological chemistry, food, energy, microelectronics, nanotechnology, and environmental protection.
