This course will help you determine whether replacing your current ion-exchange (e.g. zeolite softener) will cut your overall industrial water treatment costs.

Course Outline

After participating in this seminar you will be able to:

  • Determine whether replacing your current ion exchange (e.g. zeolite softener) will cut your overall water treatment costs
  • Assist your employer in meeting stricter environment legislation
  • Understand the importance of well-designed and operated pre-treatment systems upstream of your RO plant to increase overall plant reliability and lower operating costs
  • Monitor key performance indicators and avoid data clutter
  • Predict fouling conditions before they bring down your plant or downstream process, costing you production losses and costly membrane replacements
  • Troubleshoot RO systems and associated pre-treatment determine what constitutes a successful chemical-cleaning regimen to maximize membrane life


Membrane processes such as reverse osmosis (RO) and nanofiltration (NF) are playing an increasingly important role around the world, and Canada is no exception. The installed RO capacity in Canada has more than doubled in the last five years alone. If you do not already operate such a system now, it is likely you will in the not-too-distant future. Membrane technologies are now found across a wide number of industries and applications. Cost efficiencies versus more traditional ion-exchange processes (e.g. zeolite softening, dealkalization, and demineralization) and environmental benefits are the main drivers of change to this revolutionary technology.

This course is practically oriented, with a half-day Workshop on the 3rd day where participants will be able to apply their newly acquired knowledge through the review of real-life case studies.

This course will help you determine whether replacing your current ion-exchange (e.g. zeolite softener) will cut your overall industrial water treatment costs. How RO can often assist your employer meet stricter environment legislation. It will help you understand the importance of well-designed and operated pre-treatment systems upstream of your RO plant to increase overall plant reliability and lower operating costs.

Who Should Attend

Facility/utility engineers, environmental engineers, consulting engineers, technologists, technicians, operating personnel or anyone requiring a working level knowledge of the theory and practice of reverse osmosis plants. This course will be of particular interest to anyone involved in the operation and maintenance of reverse osmosis or nanofiltration systems.

Here are some reviews of the training vendor.
The course was very well presented and the course instructor was absolutely amazing.
Reviewed by 2013
Our instructor, Stephen Lamming, was outstanding and a true expert in his field. He was able to complement the technical air monitoring information with practical real life examples which was highly beneficial. He is an excellent communicator and was highly interactive with the course attendees. This course was recommended to me because Stephen Lamming does an outstanding job. I was very impressed with this course and have subsequently recommended it to my colleagues.
