Problem Formulation

Figure C2.1 illustrates the equilibrium data for protein uptake by a cellulose ion exchanger.

Waste water with a protein concentration of 200 mg /1 is considered.

The break-point will be considered as the time at which the effluent has a protein concentration of 20 mg /1 and the bed will be considered exhausted when the effluent has a protein concentration of 180 mg/l.

The depth of the ion exchange bed is 0.5 m.

Find Za and the saturation in percentage.
