3.6. Total Dissolved Solid (TDS) (mg/L)
The mean value of TDS of inlet samples (B) and outlet samples (A) from system S1 is found to be 760.50 and 709.25, respectively, for premonsoon season and 794.00 (B) and 527.20 (A) for postmonsoon season. After treatment by ozone, the mean TDS values are 732.25 and 687.50, respectively, for B and A samples of premonsoon season and 792.80 and 529.25, respectively, for postmonsoon season. There was not any significant difference in total dissolved solids after ozonation (). The TDS values are shown in Figure 7
