Abstract (EN):
The methods for designing ion exchange equipment, namely batch, continuous perfectly mixed and fixed beds, are discussed.
For each type of equipment we get, either analytically or numerically, the solution concentration (and resin concentration) as a function of time by using three different models:
equilibrium model
film diffusion model
homogeneous particle diffusion model.
In all cases the ion exchange equilibrium isotherm is nonlinear.
The numerical solutions were obtained using the method of lines with a finite element collocation technique for the spatial coordinate.
