Reverse Osmosis Pretreatment Course RegistrationSCTCbanner.gif (3644 bytes)

Reverse Osmosis (RO) Pretreatment gives the pretreatment requirements necessary to enable a long life expectancy from the RO membrane elements.  It explains how to prevent scale formation, minimize membrane fouling, and how to protect the RO membrane from incompatible substances.  It describes how the various pretreatment options are meant to be correctly applied in a manner that is appropriate for the downstream RO system.

This course certifies that the participant has the skills to properly evaluate and optimize the design and operation of RO pretreatment equipment so as to optimize RO performance.

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 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).
