Bio Adsorption: An Eco-friendly Alternative for Industrial Effluents Treatment 53

Figure 3.10. Graph obtained in Reactor App by entering the data of the breakthrough curves of the fluid dynamic test (pink

dots) and the adsorption of Lead (II) on dolomite (light blue dots). The red area represents the amount of adsorbed lead, the

text in Spanish additionally indicates the base line area, the difference between these both areas and the adsorbed amount in

mmol.

copper (II) adsorption on Azolla pinnata in the continuous reactor.

approximation for the scale-up can be made. Once the continuous reactor is built, the results can be

analyzed with Reactor App and the models can be used to parameterize the new reactor. In this way

it is possible to consider a new scale jump.

In all the cases studied in our laboratory, the obtained results indicate that the use of

lignocellulosic materials for the removal of ionic pollutants from wastewater is feasible, taking into

account that the use of these materials is a contribution to the circular economy.

We are working on the mixing of contaminants and multiple adsorptions on these adsorbents,

as well as on the safe final disposal of these solids when exhausted.
