This study demonstrates the applicability of particle counting technology for analysis of various water treatment systems at the Rocky Flats Plant. The Particle Analysis System determined the water quality of samples from environmental remediation, storm water treatment, and drinking water treatment operations. samples were measured in either discrete or on-line mode. This data showed filtration efficiencies, particle counts, particle size distributions, and real-time treatment system performance. Sample dilution, handling, and background techniques were also evaluated and utilized in this study. Particle counting indicated water quality changes after the range of 0.0 nephelometric turbidity units (NTU) was achieved. In the environmental remediation treatment process on-line monitoring, less than 1,000 total particle count resulted in turbidity of 0.0 NTU, but filter efficiency improved to approximately 500 total particle count with no change in turbidity. Filter removal efficiency improved with time because previously retained particles serve as additional collectors for other suspended particles. This was shown by comparing filtration before and after backflushing. Particle counting can be used to evaluate the filter cleaning process (backflushing) capability by measuring immediate post-filter performance. The Particle Analysis System proved to be an efficient and reliable water quality measurement tool, and it is applicable to a variety of water treatment systems at the Rocky Flats Plant.
