Greater Cincinnati Water Works (GCWW) recently completed an ultraviolet (UV) process master plan (UVMP) for the Richard Miller Treatment Plant (RMTP)
to identify the best way to implement UV treatment technologies to address both disinfection and
micropollutant destruction over the next 20 years. Specific treatment objectives included:
enhanced disinfection for Cryptosporidium and emerging microbial pathogen
inactivation;
advanced oxidation for seasonal taste and odor control (specifically MIB reduction); and,
advanced oxidation for destruction of emerging contaminants in the Ohio River,
including the four chemical contaminants cited above.
The UVMP evaluated a large matrix of design alternatives including: 15 UV disinfection and UV
advanced oxidation process (UV/AOP) design alternatives; three plant site locations; and, two
process train locations (pre-GAC and post-GAC). The intent was to identify all possible
combinations of UV-based disinfection and AOP technologies for RMTP, systematically
evaluate and rank them, and select one or more alternatives for guiding the final design of the
UV Facility for RMTP. A benchmark analysis was also performed to compare UV/AOP design
alternatives against the ozone/peroxide AOP process, since the latter is well established as an
AOP process for municipal drinking water applications. The results of these evaluations are
presented in this paper.
A UV process simulation model (UVCAT) was used in conjunction with input from the UV
vendors and a literature review to predict disinfection and advanced oxidation treatment
performance for the various design alternatives. The results of the UVCAT evaluations are
summarized in this paper, and discussed in more detail in a companion paper (Wright, et. al, 2008). Includes reference, tables, figures.
