This powerpoint presentation outlines a RCR Project in Dinuba, California, that used ultraviolet (UV) disinfection application for high quality reclaimed water. The presentation provides information on reclaimed watertreatment regulations that include: disinfected tertiary recycled water criteria, according to the California Code of Regulations; NWRI 2003 UV Guidelines andUV design criteria; and, criteria not appropriate,high quality percolated effluent. Topics covered under Reclaimed Water Quality include: Percolation Results inExtremely High UVT; similarity of Turbidity and PSD of PercolatedWater; and, Microorganisms - No DetectableMS Phages or Coliforms in Percolated Water. Determination of UVDesign Parameters includes a comparison of conventional design costs. UV system selection includes: open channel or in-vessel; performance-based selection; and, Aquionics In-vessel Reactors. Conceptual UV SystemDesign and Costs looks at: UV system design; conceptual layout; and, substantial cost savings. Next steps include:regulatory issues for 60 mJ/cm² dose;2-log virus removal credit for percolation;bacteriophage method detection limit;Fresno reuse application status;seeking virus credit for SAT from CaDHS; and,in the meantime - irrigation restrictions. Includes tables, figures.
