Performance of Biomass Adsorber Column for Competitive Removal Pb(II), Cr(III) and Cd(II) ions from Synthetic Wastewater
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 7
Abstract
The adsorption of Pb(II), Cr(III) and Cd(II) onto dead anaerobic biomass (DAB) in single, binary and ternary system was studied using fixed bed adsorber. A general rate multi- component model (GRM) was utilized to predict the fixed bed breakthrough curves for triple-component system. This model considers both external and internal mass transfer resistances as well as axial dispersion with non-liner multi-component isotherm (Langmuir model). The effects of important parameters, such as flow rate, initial concentration and bed height on the behavior of breakthrough curves were studied. The equilibrium isotherm model parameters such as isotherm model constants, pore diffusion coefficients were obtained from the batch experiments. The results showed that the GRM was found suitable for describing the adsorption process of the dynamic behavior of the DAB adsorber column.
