Webinar: MWF Microbiology - Monitoring Microbial Contamination

Wednesday, August 21, 2013

12:00 PM - 01:30 PM

Join us for this webinar addressing condition monitoring of microbial contamination, with instructor Fred Passman.

MWF Microbiology: Monitoring Microbial Contamination

Instructor: Dr. Fred Passman, BCA, Inc.

Where: STLE University, live webinar event broadcast to your computer

When: Wednesday, August 21, 2013 at 12-1:00 p.m. CST, with optional Q&A from 1-1:30

Cost: $39 for members, $59 for non-members


This presentation builds on the foundation laid during the MWF Microbiology Basics webinar.  However, it is also useful as a stand-alone program.

Condition monitoring (CM) for microbial contamination shares common features with other routinely performed MWF CM.  However, there are several concepts that are unique to microbiological sample collection, handling, testing and data interpretation.  Optimal MWF management depends on understanding these unique concepts.  During this webinar, Dr. Passman will provide a very brief overview of the microbiology basics as a refresher for those who have participated in the earlier webinar and a means of bringing newcomers up to speed.

He’ll then discuss some of the most critical elements of microbiological sample collection.  The underlying concept behind this information is that the microbiology of the bulk MWF is very different from that of surface and aerosol samples.  Low numbers of microbes in bulk fluid samples can give a false sense of effective contamination control.  Moreover, samples intended for microbiological testing are quite perishable and need to be handled accordingly.  Dr. Passman will describe best practices for handling microbiological samples from time of sampling to the initiation of testing. 

The greatest portion of the webinar will focus on a discussion of the methods that are most useful for microbiological CM.  There is no single microbiological test that provides all of the relevant information about MWF microbial contamination.  Dr. Passman will describe the methods, the type and value of information each method can and can’t provide and best use of data for system management.

Although the webinar won’t discuss strategies for controlling microbial growth, it will provide the foundation of information needed to help plant operators and fluid managers to design cost-effect condition monitoring and microbial contamination control progams.


Dr. Passman is an STLE Fellow and Certified Metalworking Fluids Specialist with 35 years’ experience in environmental-industrial microbiology. Since 1973, Dr. Passman has conducted research and consulted to government and private industry on topics as diverse as composting municipal sewage sludge, U.S. EPA criteria for various groups of toxic substances in fresh-water systems, microbially enhanced oil recovery, and microbial contamination control in industrial process-fluids.  He is a member of numerous professional and trade organizations including ASTM and STLE. Within STLE, he is currently the Chair of the Education and Certification Harmonization Ad Hoc Committee. Dr. Passman is Chair of ASTM Subcommittee E.34.50 Health and Safety of Metalworking Fluids, Vice-chair of ASTM Committee E34 Occupational Health and Safety and is an active member of E.35.15 Antimicrobial Pesticides. He has drafted ASTM Standards for each of these committees.  Dr. Passman has twice received STLE’s Wilber Deutsch Memorial Award for writing excellence, and is a recipient of STLE’s P.M. Ku Award.  He has more than 40 publications to his name.
