Types of Pleated Membrane Filters
Pleated Membrane Cartridges
Pleated membrane cartridges are widely used across various industries. They feature a large surface area, which allows for higher dirt-holding capacity and longer service life. These filters are suitable for applications such as pharmaceuticals and food and beverage processing.
Sterile Filtration
Sterile filtration is critical in environments where product sterility is paramount. These filters, often made from PVDF, ensure that no microorganisms are present in the final product. Industries like biopharmaceuticals utilize these filters to maintain the integrity of their products.
Microfiltration
Microfiltration is a common technique used for water treatment. Filters made from nylon effectively remove bacteria and larger particles, making them suitable for applications such as ultrapure water (UPW) production. They are also cost-effective, providing good performance without breaking the bank.
Depth Filters
Depth filters offer a different approach to filtration, capturing particles throughout the filter material rather than just on the surface. Made from polypropylene, they are ideal for various industrial processes where high flow rates are needed.
Membrane Pleated Filters
These specialized filters, often made from PTFE, are used in semiconductor manufacturing and other applications where chemical compatibility is crucial. Their unique structure allows for high filtration efficiency while maintaining flow rates.
Applications of Pleated Membrane Filters
