Two-stage crosscurrent batch sorption design of cadmium and zinc removal onto iron-modified zeolite - minimum contact time optimization approach
In highly congested industrial sites in which significant volumes of effluents have to be treated in the minimum contact time, the application of a multi-stage batch reactor is suggested. To achieve 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, a two-stage batch sorption design approach was applied to experimental data of cadmium and zinc uptake 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 optimise 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. The benefits and limitations of the two-stage design approach have been investigated and discussed.
