FREE to members.
Fee for non-members $30+HST.


Common engineering plastics can be found almost everywhere in water & wastewater treatment equipment due to their versatility, availability, and affordability. Unfortunately, there are dozens of different brand names, colours and material types on the market, and so there is widespread confusion about the differences in mechanical and material properties, and how the material selection will ultimately determine the performance and service life of the components. This session will start with an overview of the main differences between the most common plastic type materials found in bearing & wear pad applications (nylon, UHMWPE, PTFE (Teflon), rubber, etc.), and identify some of the typical equipment applications where each material might be found. We will go over the 5 simple ways to help maintenance & reliability staff to extend the life service life of these non-metallic wear components through better understanding of design, lubrication, working environment, and the influence of load & speed. Several real-life examples will be presented where the service interval of “plastic-type” components in wastewater treatment equipment was extended, maintenance was reduced, or oil & grease was eliminated completely.

At the completion of this one-hour OJT session, participants will be able to demonstrate the following:

              • Gained knowledge of the typical non-metallic wear pad, bushing & bearing applications found throughout water & wastewater process equipment
              • Increased knowledge of the material & mechanical properties that affect non-metallic component life
              • How to extend the replacement interval of these components when subjected to severe working environments
              • Understanding of how to select optimal “plastic-type” materials for maximum life and performance

    • Facilitator:

      Greg Auger

      Our facilitator is Greg Auger, one of the co-founders of Millstream Engineering.  Greg is a Mechanical Engineer with 20 years of experience in testing, design, and application engineering of mechanical components for rotating equipment.  Through his previous work with Thordon Bearings, Greg has worked in Hydropower and Industrial markets around the world but is now focused closer to home, supporting customers in Ontario who need engineered bearings and wear products that can extend operational life and reliability.


      These 1-hour virtual sessions are offered every alternate Thursday starting at 2:00 pm.  Sessions are complimentary to all OMWA members and the fee for non-members is $30.00 CAD plus HST per person per session.  

      If you have any specific questions regarding this OJT session, please feel free to submit them when you register and we will provide them to the workshop facilitator.   

      The OMWA will provide a certificate recognizing participation in these On the Job Training sessions.
      Attendance may also qualify as a Continuing Knowledge Activity for the PEO PEAK program
