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 water
treatment regulations that include:
disinfected tertiary recycled water criteria, according to the California Code of Regulations; NWRI 2003 UV Guidelines and
UV design criteria; and, criteria not appropriate,
high quality percolated effluent. Topics covered under Reclaimed Water Quality include: Percolation Results in
Extremely High UVT; similarity of Turbidity and PSD of Percolated
Water; and, Microorganisms - No Detectable
MS Phages or Coliforms in Percolated Water. Determination of UV
Design 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 System
Design and Costs looks at: UV system design; conceptual layout; and, substantial cost savings. Next steps include:
regulatory issues for 60 mJ/cm<sup>2</sup> 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.
