Abstract
The invention relates to a method for purifying a solution, the method comprising the following successive steps: —bringing a solution to be purified into contact with an ion exchange resin by suspending the ion exchange resin in the solution to be purified, the ion exchange resin having the form of particles having a size Dv50 smaller than or equal to 200 μm; —separating the solution into a purified solution and a loaded resin; —regenerating the loaded resin by passing at least one regenerating solution through a compact bed of loaded resin. The invention also relates to an assembly for implementing the method.
