The Computer Controlled Ion Exchange Unit ,"EIIC", has been designed by EDIBON to study water softening in a single bed or water demineralization in a double bed system.
The Computer Controlled Ion Exchange Unit, "EIIC", is a self-contained unit consisting of a panel with two transparent columns to be filled with anionic and cationic resins, plus a spare column and a computer controlled pump that supplies the effluent from the tanks attached to the pipes, forming different circuits, depending on the softening, demineralization or regeneration process to be carried out.
The flow of the pump can be regulated and can be read in a flow sensor before the inlet of the first ion exchanger.
A conductivity meter connected to the outlet of the unit allows the students to measure the process and a useful and easy checking of the ionic exchange evolution.
The unit includes the most usual resins used in the process of softening water (styrene sulfonate, in its sodium form), which have a strong affinity with calcium and magnesium ions.
When these have been eliminated, the solution also eliminates or retains the ferrous ion.
The computer controlled diaphragm pump circulates the water through the different circuits of the equipment: through an anionic column, through a cationic column and then through an anionic and cationic column.
The unit allows for exchanging different materials, the resins and reagents employed, as well as the problem water.
This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
