Michael retired in 2016 after a long distinguished career with Toronto Water where he served as the Manager of the Toronto Water Laboratory, a group of municipal laboratories that provide analytical services meeting the diverse needs of Toronto Water.

 

Michael has had almost 32 years of laboratory experience, specializing in water treatment. He began in the public sector working for the former Metropolitan Toronto Department of Works. He worked his way up from the laboratory bench in various water treatment plants becoming a plant Chief Chemist. During this time a large part of his responsibility involved working with plant staff providing technical training for process analyses including both manual and on-line equipment. Quality Control of the finished product was another area he worked closely on with plant operations staff. Municipal amalgamation in 1998 would eventually lead to the formation of Toronto Water. Michael’s responsibilities changed to include the running of the drinking water distribution sampling program for Toronto Water. In 2006 he was promoted to his current position as Manager. His laboratories are responsible for the analysis of samples from a variety of sources including drinking water, wastewater, industrial wastes, landfills as well as lakes and streams.

 

Michael’s personal experiences in both the laboratory and in the plant make him uniquely qualified to deliver training to operators and water quality analysts. He continually attends conferences and seminars to remain current on drinking water treatment issues. He has presented at seminars and conferences on issues related to laboratories and drinking water regulations. One of his latest work-related initiatives was to closely examine lead levels in drinking water and upcoming changes to wastewater effluent regulations.

 

 

Title:  Advanced Water Treatment

The objective of this course is to provide participants with training in advanced water treatment plant processes. The course material will provide a description of the finite global water resource, a review of early water systems and an explanation of conventional water treatment. This will be followed by a description and explanation of advanced water treatment processes including activated carbon, ozone disinfection, ultraviolet light disinfection and four methods of membrane filtration. Advanced oxidation processes AOPs will then be introduced including ozonation and ultraviolet light combined with hydrogen peroxide.

 

Each treatment process will be described in conjunction with the specific contaminant or pathogen that it is capable of removing, destroying or inactivating. Since water treatment processes work in conjunction with each other, the benefits of various treatment combinations will be explained in the training. For instance, ozonation is positioned before biological filtration to minimize disinfection byproducts in the treated water. Ultraviolet light may be used in conjunction with hydrogen peroxide as an advanced oxidation process to destroy organic contaminants.

 

The training manual will provide the latest information on current and emerging issues and the advanced technologies best suited to treat them. Some of the issues that will be discussed include: cyanobacterial toxin microcystin LR, taste and odour compounds such as geosmin and MIB, organic contaminants such as NDMA, 1,4 dioxane and pesticides, endocrine disruptor compounds (EDCs), pharmaceutical and personal care products (PPCPs) and pathogens such as Cryptosporidium. The use of elevated pH and corrosion control inhibitors to reduce lead residues may also be explained.

 

Videos will be used to illustrate and explain the operation of each advanced treatment process. Participants will work in groups on crossword and word match exercises to reinforce their knowledge. Opportunities for hands-on demonstration of treatment equipment such as membranes will be included to maximize learning and retention. In addition, participants will work together to calculate the disinfection CT value for a hypothetical advanced oxidation treatment process.
