Presenter: Grant Dixon
Iron and Manganese Removal in Groundwater and Surface Water Facilities.

In 2020 the Guidelines for Canadian Drinking Water Quality (GCDWQ) were updated to reflect new water quality standards for iron and manganese. More specifically manganese limits with an Aesthetic Objective (AO) of .02 mg/l and a Maximum Acceptable Concentration (MAC) of 1.2 mg/l.
Iron and Manganese removal has traditionally been an ground water issue in the Prairie Provinces and a nuisance in surface water facilities especially during winter months. With the implementation of the new standards and in particular a MAC for manganese requires water treatment facilities to implement methods to control the level of iron and manganese in their treated water supplies.
In this workshop we will examine:

- The “source” of iron and manganese in our source water.
- The CDWQG and the new requirements for manganese limits
- The basics of water chemistry related to iron and manganese.
- Iron and manganese removal processes.
- The role of filtration, when it work and why it doesn’t always work.
- Troubleshooting iron and manganese removal in our Water Plants.

The 4- hour workshop will be lead by Grant Dixon Manager of ATAP Alberta and Manager of Regional Water Alberta North, with technical presentations by Nicholai Kristal P.Eng Process Engineer, Associated Engineering and Dr Sutha Suthaker P.Eng, National Water Practice Leader, Associated Engineering.

Dr. Sutha Suthaker is the National Technical Specialist of Water Treatment, for Associated Engineering. Sutha provides leadership and technical support in water treatment processes to clients and staff across Canada. Sutha have over 30 years of experience in design and optimization of biological/physical-chemical processes in the treatment and disinfection of surface water and groundwater for municipal and industrial uses. Sutha has been involved in numerous process optimization studies, completed many bench-scale and pilot testing assignments, and has assisted various clients with troubleshooting water treatment issues.

Nicholai Kristel, Process Engineer- Associated Engineering
Nicholai Kristel is a Process Engineer, in the Regional Water Division in Edmonton. He has over
8 years of process design, water quality assessments, and consulting engineering experience.
Nicholai primarily works on municipal water and wastewater projects, where he uses his
experience to model and design biological and physical-chemical processes in the treatment of
water. Prior to joining Associated Engineering, Nicholai completed a Bachelors of Science
Degree in Microbiology and Immunology at McGill University. Subsequently, he spent 4 years
working in water quality laboratories at various facilities in Northern Alberta. From this
experience, he gained a strong understanding of industrial water and wastewater treatment
processes, water quality parameters, and water testing procedures


Presenter Bio:
Grant Dixon is the Manager of ATAP Alberta with experience in both water and wastewater
systems. He has over 25 years of experience as a utility operator and manager, and has worked
extensively for Municipal and First Nations clients. His background includes process
troubleshooting, operator assistance and mentoring, pilot- and bench-scale testing, risk
assessments, SOPs and emergency response planning, start-up and commissioning, and project management. Grant also instructs Class 1 and 2 Operator Certification Training.
