Filtration Sizing
Use this general guide to determine the optimal type of filtration and sizing for your particle sizes. Each type of filtration is designed to separate differing ranges of microparticles and particles:
- Ultrafiltration is best with particles of roughly 10,000-1,000,000 MW;
- Microfiltration is best with particle sizes of roughly 0.1-10im;
- Macrofiltration is best with particle sizes greater than 50 im.
