Sanitek has the answers to common questions about capsule filter and filter cartridges in critical process filtration.
How Are Filter Cartridges Used and How Do They Work?
Membrane filter cartridges are used for precise liquid filtration in applications where consistent particle retention is essential, such as pharmaceuticals, food and beverage, laboratory, and specialty chemical processes. They are typically installed inside filter housings and integrated into a filtration system as the final or intermediate step in removing particulates, microbes, or other contaminants.
These filter cartridges work by forcing liquid through a pleated membrane structure made of materials like PES, PVDF, PTFE, or nylon. The pleated design increases the surface area, allowing for higher flow rates, lower pressure drops, and extended service life. Depending on the application, membrane filters can be used for sterilizing filtration, clarification, or prefiltration—ensuring product quality, sterility, and system protection.
Common Questions About Process Filtration
What is the right micron size filter for me?
What is the right micron size filter for me?When selecting the appropriate micron size filter, it’s essential to focus on the level of filtration required for your specific application. If you need to remove fine contaminants, such as bacteria or other small particles, filters with smaller micron sizes, like 0.2 or 0.45 microns, are often the best choice.
The selection process also depends on factors like the flow rate and the characteristics of the liquid or gas being filtered. Consulting with a filtration specialist can help ensure that you choose a filter that meets your specific needs without compromising the efficiency of your system.
Can these cartridge filters be reused after cleaning?
No, we only provide single-use filters.
What contaminants are removed by cartridge filters offered by Sanitek Filter?
Sanitek Filter’s cartridge filters are designed to effectively tackle a range of contaminants across different applications. Our filters are engineered to remove various types of particulates, from fine particles and sediments to microorganisms like bacteria and viruses. They are particularly effective at addressing impurities that could affect the quality and purity of liquids in critical industries such as food and beverage processing, biopharmaceuticals, fine chemicals, and semiconductor manufacturing. By utilizing advanced filtration technologies, our cartridge filters ensure that the fluids are thoroughly cleaned to meet stringent quality standards and operational requirements.
What is the difference between a capsule filter and a membrane cartridge filter?
The main distinction is in their design and filtration mechanism. A capsule filter is a compact unit that can contain various types of filter media, including membranes. It typically has a smaller filtration area, designed for small-scale applications and single-use scenarios.
In contrast, a membrane cartridge filter consists of a cylindrical housing filled with a specific membrane material for precise filtration. Cartridge filters are often used in larger-scale industrial applications requiring high-efficiency filtration. While both filters can include membranes and serve the purpose of removing contaminants, but their size, filtration area, and reusability options differentiate them based on specific filtration requirements.
What Industries Use Sanitek’s Filter Cartridges?
Sanitek filter cartridges are used across a wide range of industries, including pharmaceuticals, food and beverage, laboratory research, and specialty chemicals. Each cartridge is designed to meet the specific requirements of these applications in terms of chemical compatibility, cleanliness, and filtration efficiency.
Can Sanitek’s filter cartridges fit in standard filter housings?
Yes. Sanitek cartridges are compatible with most standard filter housings. We offer various end cap configurations and sizes to ensure a proper fit across different systems.
What kind of fluids can be filtered?
Sanitek filter cartridges are suitable for filtering a wide range of liquids, including water-based solutions, buffers, solvents, culture media, cleaning agents, and various process fluids used in pharmaceutical, food, and industrial settings.
What is the difference between surface filtration and depth filtration?
Surface filtration captures particles on the membrane surface and is typically used for precise, size-based separation. Depth filtration traps particles within the thickness of the media and is suited for fluids with higher particle loads, as it allows for greater dirt-holding capacity.
