This present study focused, full factorial design modeling to achieve the optimum treatment conditions on removal of zinc from the industrial wash water. After experimentation, mathematical model for zinc removal was developed to correlate the influences of process parameters and output response. The main & interactive effects of three different experimentally controlled factors were investigated. The contribution percentage of each factor were obtained in the ascending order as Initial Concentration (15.49%) < Current Density (22.19%) < Time (25.29%). The experimental result analysis showed that the combination of higher level of initial concentration and lower levels of both current density and time is essential to achieve maximization of zinc removal rate. ANOVA was used to find out the most significant parameters which affect the response characteristics. Results also show that about 100% of zinc removal can be obtained at optimum conditions.
