To optimize water treatment processes, water treatment plant operators need access to a variety of techniques for monitoring and measuring how well the treatment plant is operating. This article describes using a $6 polypropylene filter cartridge to observe filter color, wash‐water characteristics, and centrifugate characteristics as an effective technique. Samples of raw and finished water are collected following the protocol used for microscopic particulate analysis (MPA) for filter plant optimization. Sample collection points along with frequency, length, and timing of sampling are determined by the individual utility, depending on the goals and resources of that utility and operations‐process control staff availability.
