Reverse Osmosis Chemistry Course RegistrationSCTCbanner.gif (3644 bytes)

Reverse Osmosis (RO) Chemistry introduces water chemistry by explaining the difference between dissolved and suspended solids, and in explaining the nature of charge that allows salts to dissolve in water.  It demonstrates how to convert contaminant concentrations between different units, and how pH and alkalinity are related to the water acidity.  It also introduces the nature of the semipermeable membrane used in reverse osmosis and how its boundary layer characteristics are related to membrane fouling.

This course assists the participant in building a fundamental understanding of water chemistry as relates to the performance of reverse osmosis membrane technology.

For this course, you will need to pay the tuition and registration fees, and purchase or be able to access the course CD-ROM and the course textbook.  Total cost for a new HPW program participant is $775.00, plus shipping and sales tax (where appropriate).  Those with access to the RO book 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).
