SKU: AG-386

Ion Exchange Unit

“AG-386” unit is self-contained unit composed by a panel, where 2 transparent columns are situated in order to put anionic and cationic resins, and also, a spare column, a pump, which supplies the material from the joined pipes. That forms different joined circuits, according to the
type of the process that can be slight, taken out the minerals and regeneration. A conductivity meter connected to the exit of the unit allows that the students measure the process and a useful and easy checking of the ionic exchange evolution. Also includes a flow meter.
The unit includes the most usual resins used in the process of softening water (sulphonated styrene, in its sodium form), that have a strong affinity with calcium ionic and magnesium. When these have been eliminated, the solution is also eliminated or can retain the ferrous ion.
The pump with membrane facilitates the circulation of water along the different circuits of the unit: Flow through an anionic column. Flow through a cationic column. Successive flow through anionic and cationic column
