Energy Efficiency Evaluation of Benchmarked UF/H2O2 Pilot Reactors for EDC Destruction with Conventional and GAC-Contacted Water
用常规水和GAC接触水破坏EDC的基准UF/H2O2中试反应器的能效评估
A twelve month pilot study on ultraviolet (UV) advanced oxidation was conducted by Greater
Cincinnati Water Works as part of an international research collaboration including
the Water Research Foundation. This study used a 55 gpm pilot unit consisting of a
single-lamp medium pressure reactor (MP) and an 8-lamp low pressure reactor (LP)
operated under a constant feed of hydrogen peroxide (10 mg/L). The advanced
oxidation process (AOP) was set to target an 80% degradation of atrazine and 55%
degradation of MTBE under all testing conditions. The pilot influent alternated
between conventionally treated and post-GAC plant water to examine the effect of
varying seasonal water quality. Seven contaminants of interest (atrazine,
metolachlor, MTBE, MIB, ibuprofen, gemfibrozil and 17-a-ethynylestradiol) were
spiked at the pilot unit on a quarterly basis. The energy requirements of the process
were captured reflecting fluctuations in water quality. Includes 3 references, table, figures.
