Filtration principles and filter technologies
Filter cartridges for industrial liquid filtration
Filter cartridges are used within industrial liquid filtration for removing unwanted particles from liquids.
Depending on the required filtration level, liquid properties and process conditions, different types of filter cartridges can be applied.
Profiltra supplies filter cartridges for a wide range of industrial applications and filtration processes.
Different filtration principles for different applications
Within the filter cartridge range, different filtration principles are available, including:
- Absolute filtration
- Depth filtration
- Surface filtration
The choice for a specific filtration principle depends on factors including particle size, viscosity, dirt load and the required filtration performance.
Membrane and pleated filter cartridges
Membrane cartridges are used within processes where absolute filtration is required, including applications within the food, beverage and pharmaceutical industries.
Pleated filter cartridges feature an increased filtration surface due to the folded filter media. As a result, they combine high accuracy with high dirt-holding capacity and long service life.
Filter cartridges for specific process conditions
Meltblown filter cartridges
Meltblown filter cartridges are used for liquids containing larger suspended particles and a broad particle size distribution.
These cartridges operate according to the depth filtration principle, where filtration takes place throughout a thick filter medium. The cartridges are characterised by low pressure drop and a cost-efficient filtration solution.
Resin bonded filter cartridges
Resin bonded filter cartridges are suitable for applications involving viscous liquids.
The construction consists of multiple layers with phenolic resin and is suitable for filtration processes where higher viscosities occur.
Filter cartridges tailored to process conditions
Depending on the filtration process, filter cartridges are available in different versions, filtration levels and configurations for a wide range of industrial applications.
