Sažetak
In highly congested industrial sites in which significant volumes of effluents need to be treated in the minimum contact time, the application of a multi-stage batch reactor is suggested. To achieve a better balance between capacity utilization and cost efficiency in design optimization, a two-stage batch reactor is usually the optimal solution. Thus, in this paper, the two-stage batch sorption design approach was applied to experimental data of Zn and Cd capturing onto iron-modified zeolite. The optimization approach involves the application of the Vermeulen's approximation model and mass balance equation to kinetic data. A design analysis method was developed to optimize the minimum total contact time by combining the time required in the two stages, in order to achieve the maximum percentage of cadmium and zinc removal using a fixed mass of zeolite sorbent. Benefits and limitation of the two-stage design approach have been investigated and discussed.
