ION EXCHANGE
(RCION)
Format: Video
O V E R V I E W
Ion Exchange introduces trainees to the ion exchange process, ion exchange equipment, and operator responsibilities associated with the startup, operation, and regeneration of ion exchangers. After completing the unit, trainees should be able to describe the chemical principles of ion exchange, identify the main components of a typical ion exchanger, and describe the differences between single-bed and mixed-bed exchangers. Trainees should also be able to explain how a typical ion exchanger is started up, backwashed, and regenerated.
O B J E C T I V E S
Introduction
- Identify typical ion exchange applications and describe the basic chemical principles behind ion exchange.
