The Castaic Lake Water Agency (CLWA) purchased six Met One in-line particle counters for each filter of its Rio Vista Water Treatment Plant (RVTP) as well as a batch particle counter from Spectrex. The individual filter effluents were monitored using the in-line particle counters and the raw water, clarified water, and combined filter effluent were monitored using the batch particle counter. In order to determine if the batch counter could be used as a master counter, two series of experiments were conducted. In the first series, the in-line and batch counters were compared directly under several different conditions to see how they compared in terms of total counts, distribution of counts, and over time. In the second series, a number of different particle standards were used to assess the accuracy of the batch counter in terms of total counts and the distribution of counts. The goal of these experiments was to use the batch counter as a master counter to perform calibration checks on the in-line counters. The objective was to prove whether the batch counter could obtain accurate and reproducible results based on particle standards and that when the in-line particle counters were in proper calibration they agreed with batch counter, then when the in-line counters were out of calibration or otherwise not functioning properly, the batch counter could be used to identify the existence of the problem and assess the nature of the problem.
