3 Terms and definitions
The following terms and definitions apply to this document.
3.1 Filtration efficiency
etax
At a given fluid particle concentration and flow rate through the filter element, the filter element is greater than a given size (x) of solid particles
Filter out the percentage.
That is, etax =
N1-N2
N1 ×
100%
In the formula.
N1 --- filter element upstream unit liquid volume greater than a given size (x) of the number of solid particles;
N2 --- filter element downstream of the unit liquid volume greater than the same size (x) of the number of solid particles.
