Electrodialysis & Electrodeionization Course RegistrationSCTCbanner.gif (3644 bytes)

Electrodialysis Reversal (EDR) and Electrodeionization (EDI) relates concepts of ionic conductivity and electricity to electrochemistry, as it applies to electrodialysis reversal (EDR).  It discusses how ion exchange membrane sheets and electricity can be used to move ions out of a feed water stream into a concentrate stream in the EDR process.  Scale control is performed by switching electrode polarity and reversing the movement of ions.  Ion exchange resin beads can be added within certain chambers of the device as a means of continuously achieving even higher purity effluent water in the EDI process.  The EDI operational and maintenance requirements are examined closely in this course.

This course certifies that the participant has a fundamental understanding of the principles involved in electrodialysis reversal and electrodeionization technologies.

For this course, you will need to pay the tuition and registration fees, and either purchase or be able to access the course CD-ROM and the course text.  Total cost for a single participant is $715.00, plus shipping and sales tax (where appropriate).  Those with access to the course text and course CD only need to pay the tuition of $415.00 (including associated fees).  Order below using a credit card or contact CEA (+952-471-0017).

Course Outcomes and Topics
At the completion of this course, the student will be able to:
1) understand the relationship between ionic concentrations, total dissolved solids (TDS), water conductivity and resistivity

2) explain how charge can be transferred through water suing concepts of electric potential/voltage, water electrolysis, and ionic conductivity

3) quantify the ionic movement processes using Faraday's Law when given a quantity of cells/cell pairs in an electrodialysis reversal (EDR) stack

4) identify the streams within an EDR or electrodeionization (EDI) system

5) quantify the effect of concentrate chamber concentrations as related to EDR and EDI system efficiencies

6) explain the effect of reversing electrode polarity on organic/inorganic fouling

7) understand how water splitting can be a disadvantage in EDR systems and an advantage in EDI systems

8) calculate resistance, voltage, and efficiency for a given EDR/EDI system

9) correctly start up and adjust flow rates and voltage/current for an EDR/EDI system

10) monitor EDR/EDI systems so as to know when maintenance is required

11) clean and sanitize an EDI system
