Key Concepts
There are some foundational terms and definitions central to understanding how filtration systems work. These core concepts are essential for making informed decisions in your process.
Micron Rating
The size of particles a filter can catch. The smaller the number, the tinier the particles it can trap. Use our interactive guide for real life examples and applications.
Nominal vs. Absolute Filtration
Nominal filters catch most particles, while absolute filters catch nearly all particles of a certain size.
Filter Media & Types
The material or structure used to capture unwanted particles and contaminants.
- • Depth Media: Like a thick sponge that traps particles throughout
- • Surface Media: Like a screen door that catches particles on top
- • Membrane Media: Super precise holes for exact filtering
- • Pleated Media: Folded to pack more filtering power in less space
Filter Vessels & Housings
Filter media generally sits in a vessel or housing to help manage flow rate, pressure, and temperature. They help create a controlled environment for filtration to succeed.
