Reverse Osmosis Biological Control Course RegistrationSCTCbanner.gif (3644 bytes)

Reverse Osmosis (RO) Biological Control details the equipment requirements upstream of a reverse osmosis (RO) system so as to minimize the RO maintenance requirements and increase the longevity of the membrane elements.  It begins with the treatment provided by many municipal water treatment facilities and expands this into the requirements more specific for RO systems.  This covers media filtration for removal of suspended solids, acid and scale inhibitor injection, or softening, for control of scale formation, and the removal of biocides that might be incompatible with the RO membrane.

This course certifies that the participant has the skills to minimize the potential for heavy biological fouling of an RO system and can correctly apply chemical biocides.

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).

Course Outcomes and Topics

At the completion of this course, the student will be able to:
1) Understand how bacteria are able to survive and propagate in different environments

2) Recognize the importance in preventing the formation of mature biofilm either upstream or within an RO system

3) Realize how different biocides affect the needs of bacteria in their method of controlling or killing them

4) Give the advantages and disadvantages of using the different particular biocides

5) Understand how certain wavelengths of ultraviolet light can affect bacteria

6) Correctly apply UV light systems for biological control

7) Give methods for dealing with the remnants of mature upstream biofilm

8) Apply different methods for biological control of an RO system

9) Set up an RO system for an extended shutdown
