What do People Mean?
- Percent Removal Rate
i.e.. 99%, 99.5%, 100%
- Total Removed by Count
% Of Total Particles Of A Certain Range
or Minimum Size.
i.e. 99% of all particles 10 microns and larger.
i.e. 100% of all liquid particles 8 microns and
larger, and 100% of all solid particles 8
microns and larger.

Conclusion
• Separators are critical pieces of
equipment for the smooth operation of
most all processes.
• Different applications require different
approaches, different styles of separators,
and sometimes units in combination.
• IT IS IMPORTANT TO GET ALL THE
INFORMATION CORRECT THE FIRST
TIME-- SAVES TIME AND $$
