The primary function of pre-filters is to remove larger particles beforehand, thus reducing the risk of clogging in subsequent final filters and extending their service life.
Additionally, pre-filters play a crucial role in improving filtration efficiency and maintaining consistent pre and post-filtration processes to ensure uniform product quality.
Compared to pre-filters, sterilization filters (also known as final filters) focus more on the final step of filtration. These filters have high-precision membrane materials with small pore sizes that can effectively filter tiny particles as small as 0.1μm.
Moreover, most final filters feature fixed-point sterilization (commonly known as SIP- Steam-In-Place) and online high-temperature steam sterilization to ensure thoroughness and safety throughout the filtration process.
The performance of pleated cartridge filters is significantly influenced by the characteristics of the membrane material and its pore size distribution. Therefore, selecting the appropriate type of membrane is crucial for optimal filtration.
When considering filter membrane selection, the primary factor to assess is chemical compatibility. This involves evaluating the membrane&#;s resistance to various substances such as acids, bases, and organic solvents.
There&#;s a wide array of materials available, allowing for tailored selection based on the specific chemical properties of the liquids being filtered.
For environments with strong acids or alkalis, PTFE and PP membranes are preferred. PP membranes exhibit chemical stability and resistance to acids and alkalis, while PTFE membranes offer broad chemical compatibility with solvents, acids, and alkalis, making them a cost-effective choice.
For sterilization filtration requirements, PES membranes are suitable. These membranes are known for their acid and alkali resistance, low extractables, thermal stability, and low protein binding.
Utilizing a double-layer membrane structure for sterilization filters can enhance filtration efficiency by increasing the filtration area.

Microporous glass fiber membrane filters are ideal for coarse filtration but unsuitable for hydrofluoric acid filtration. They are often used as pre-filtration material.
Hybrid cellulose ester, polycarbonate, or PVDF filter membranes are suitable for applications without acids or alkalis. PVDF membranes are even compatible with weak acid or alkali environments.
In the presence of organic solvents, nylon membranes are the preferred choice. Nylon 66 membranes exhibit compatibility with most organic and water-based solvents, except for strong acids.
Some manufacturers offer positively charged nylon pleated cartridge filters designed to efficiently remove particles by binding to the negative charge of endotoxins. These are widely used in the biopharmaceutical industry, ensuring compliance with relevant standards and regulations.

Membrane cartridge filters with an asymmetric pore structure are primarily designed for applications requiring high flow rates and high particle suspension. Membrane filters are available in various sizes and shapes, including cartridges, capsules, and disks. Brother Filtration provides a broad range of pleated membrane cartridges to meet different filtration needs.
Membrane filter cartridges work by utilizing a porous membrane material that acts as a physical barrier, capturing particles of a specific size or larger. These membranes are available in different pore sizes, typically ranging from 0.1 to 10 microns, allowing for customization based on the specific filtration requirements.
Membrane filter cartridges are highly efficient filtration devices that are widely used in various industries for diverse applications. These cartridges feature a membrane as the primary filtration medium, which allows for the precise removal of contaminants from fluids.
