How filtration is used in industry
Industrial processes depend on filtration to keep products consistent, protect consumers, and keep equipment running. Across industries, most filtration does one of three jobs.
Clarification & Particulate Removal
Larger particles are removed early, often with depth or capsule filters, so liquids run clear and downstream membranes do not clog.
Sterile & Microbial Control
Membranes with a defined pore size remove bacteria and fine particulates from liquids in food, beverage, and pharmaceutical production.
Quality Control Testing
Samples pulled from the line are filtered before analysis, such as HPLC, so results reflect the product and not stray particulates.

Which membrane fits my fluid?Aqueous, solvent, and aggressive chemical streams
- AqueousPES or cellulose acetateHydrophilic membranes that wet easily and filter water-based solutions quickly.
- SolventsPTFE or nylonCommon choices for organic solvents. Confirm the specific solvent before ordering.
- AggressivePTFE or polypropyleneChemically resistant materials for acids, bases, and harsh process streams.
Always check your exact chemical against the chemical compatibility chart.
Do I need a prefilter?When a two-stage setup saves time and money
- YesCloudy, viscous, or heavily loaded liquidsA prefilter catches larger particles so the final membrane does not clog early.
- Maybe notClean, low-particulate liquidsA single membrane may handle the batch on its own.
Industrial filtration FAQs
What is the difference between a depth filter and a membrane filter?
A depth filter captures particles throughout a thick fibrous matrix, so it holds a lot of material before clogging. A membrane filter retains particles at its surface based on a defined pore size, which makes it the choice for final and sterile filtration.
Why should I use a prefilter?
A prefilter removes larger particles before they reach your final membrane. That keeps the final filter from clogging early, extends its life, and lowers the cost per batch.
What pore size is used for sterile filtration?
Sterilizing-grade filtration uses a 0.2 or 0.22 µm membrane. For larger or heavily loaded batches, a prefilter upstream helps the final filter last.
How do I know a filter will hold up to my chemical?
Check the membrane and housing against our chemical compatibility chart before you order. PTFE handles the widest range of aggressive chemicals, while PES and cellulose acetate are built for aqueous solutions.
