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.
Claims16
A method for purifying a solution, successively comprising:
- contacting a solution to be purified with an ion exchange resin, by putting the ion exchange resin in suspension in the solution to be purified for a duration of time, thereby forming a purified solution and a loaded ion exchange resin, the ion exchange resin being in the form of particles having a Dv50 size equal to or less than 200 μm;
- separating the purified solution from the loaded ion exchange resin, thereby forming a compact bed of loaded ion exchange resin;
- and
- regenerating the ion exchange resin from the compact bed of loaded ion exchange resin, by passing at least one regenerating solution through the compact bed of loaded ion exchange resin.
