Other important parameters are strength, compatibility, efficiency and capacity. The efficiency is dictated by the particles or substances to be removed. A large-mesh filter may be efficient at retaining large particles, but inefficient at retaining small particles.
A very efficient filter may show poor capacity, causing increased resistance to flow or other problems as it plugging up prematurely and increasing resistance or flow problems. A balance between particle capture and flow requirements must be met while ensuring integrity. Archived from the original on 2012-01-07. This page was last edited on 22 November 2017, at 13:53.
