Modeling of crystal violet adsorption by bottom ash column
The removal of crystal violet from wastewater, by means of bottom ash, was investigated in a packed bed down-flow column. The bed depth service time (BDST) model was used to analyze the experimental data up to breakthrough time (corresponding to C(t)/C(0) = 0.1). A mass transfer model was used to an...

Zusammenfassung: | The removal of crystal violet from wastewater, by means of bottom ash, was investigated in a packed bed down-flow column. The bed depth service time (BDST) model was used to analyze the experimental data up to breakthrough time (corresponding to C(t)/C(0) = 0.1). A mass transfer model was used to analyze the mass transfer zone. The breakthrough curve was analyzed by the Thomas, Yoon-Nelson, and Clark models. All models fit well with the experimental data. Results showed that as the flow rate increases, at a constant concentration and bed depth, the value of the adsorption capacity of bottom ash decreases. The adsorption capacity of bottom ash decreases with an increase in depth and initial crystal violet concentration. Error analyses were performed for the Thomas, Yoon-Nelson, and Clark models.
