Abstract

Exactly how the investigator should make the comparison between the particle-size distribution in the feed stream to that in the filtrate is the subject of controversy between those who determine the cumulative number of particles versus particle diameter and those who determine the number of particles in each of many diameter ranges. The present discussion, based on the number of particles in each diameter range, addresses the question, “What width of a diameter range should be considered?”
