Plug-flow stationary solid phase upflow and completely mixed recycle fluidized adsorber experiments were conducted to test the predictive models developed earlier. Model parameters were determined independently from adsorption equilibrium, kinetic investigations, biokinetic experiments and correlation techniques. Two ideally adsorbable and biodegradable compounds, glucose and sucrose, as well as two actual wastewaters, a dairy waste and a landfill leachate, were used to compare the model profiles and experimental data of non-bioactive and bioactive adsorber systems. The performance prediction by the models satisfactorily described the experimental data.
