Pressing particle counter sensitivity lower for improved response

Overview:

This paper by Pacific Scientific Instruments, now part of Hach Ultra Analytics, compares particle counters with one-micron sensitivity to those with two-micron sensitivity at a utility in Montrose, Colo. The goal of this paper was to determine whether the inherent higher particle counts from a particle counter with one-micron sensitivity would provide more statistical confidence or measurement precision than those from a sensor with two-micron sensitivity. According to this paper, using a particle counter with one-micron sensitivity is valuable for improving water treatment process programs. Each instance cited in this paper has been related to an operational cause such as operator error or chemical feed adjustments.
