At these optimized conditions, the maximum decolorization and COD reduction was found to be 71.2 and 80.5 %, respectively.
Box Wilson experimental design method was employed to optimize the wastewater flowrate, oxidant and catalyst concentrations as significant factors for maximum decolorization and organic matter removal.
Total 24 yeasts were isolated from the soil samples of near by distillery site, in which isolate Y-9 showed maximum decolorization and identified as Candida tropicalis by Microbial Type Culture Collection (MTCC) Chandigarh, India.
The optimum values of the process variables for the maximum decolorization efficiency and the maximum values of decolorization that were verified experimentally are shown in Table 6.
[ 19] have also reported that Issatchenkia orientalis utilized 2.5% glucose for maximum decolorization (60%) and above this concentration of glucose there was decrease in the decolorization.
The maximum decolorization, TOC removal, and pseudo-first-order degradation rate constant were 94.8, 38.8, and 30.8 min−1, respectively.
Maximum decolorization of 94.5% and 90.7% for RO-16 and RR-35 was obtained at optimum concentrations of dye, glucose and ammonium chloride i.e., 0.66, 17.50 and 2.69 g/L for RO-16 and 0.68, 16.67 and 2.13 g/L for RR-35, respectively.
The water quality assurance parameters such as BOD, COD, TOC and pH were measured where maximum decolorization was achieved both for synthetic dye solution and textile wastewater.
Maximum decolorization efficiency was predicted and experimentally validated.
Also, the optimum values of the process variables for the maximum decolorization efficiency were calculated and then verified experimentally.
