Coagulant Dosage

A response surface methodology (RSM) was used for the determination of optimum coagulation process conditions for disperse navy blue dye wastewater treatment. The experimental design was Box-Behnken design (BBD) with three operational variables: coagulant dosage, pH value and settling time. The influence of these three independent variables on the chroma removal was evaluated using a second-order polynomial multiple regression model. Quadratic model was predicted for the response variable and the maximum model-predicted chroma removal efficiency was 95%. Based on surface and contour plots, the optimum conditions were obtained to be coagulant dosage of 70.98 mg/L, pH value of 7.46, and settling time of 15.80 min with the actual chroma removal efficiency as 93%.

Tempering Process

In this research, the response surface methodology with a polynomial model was used to represent the experimental data of the combination of steaming, drying, and tempering process for extra-large cashew nuts. The desired values of pre-treatment conditions minimize the broken kernel percentage and maximize the shelling capacity to achieve cost effectiveness. In the this study, the steaming, drying, and tempering conditions were optimized for the minimization of the broken kernel percentage and the maximization of the shelling capacity of extra-large cashew nuts (bigger than 32 mm). The optimal conditions were steaming temperature at 100 ℃ for 38 min, then drying at 70 ℃ for 30 min, and finally tempering for 4 h. Under these conditions, the minimal broken kernel and maximal shelling capacity achieved were 2.45 ± 0.24% and 14.58 ± 0.35 kg/h, respectively.
