| Every day millions of gallons of recycled water are produced at four Water Recycling Centers (WRC) owned and operated by the San Antonio Water System delivering recycled water to customers for non-drinking purposes. The purpose of the study is to evaluate the different parameters in order to assess and compare the effectiveness of the recycling processes of the DOS Rios and Medio Creek WRC. The contaminants analyzed were ammonia nitrogen; total suspended solids (TSS); E. coli; and trihalomethanes (THM). The water samples were analyzed using semi-automated colorimetry and GC-MS. The levels of ammonia nitrogen, TSS and E. coli of Medio Creek were consistently above those of Dos Rios. Although the THM levels were higher in Dos Rios than in Medio Creek but all the contaminants studied were well below the detrimental level in both Centers. Correlation between the treatment processes and the levels of the contaminants in the final effluents of the two Recycling Centers were also discussed. |
