Nutrient Removal

Zobia Jawed, B.Sc., M.Eng, PhD Candidate


Instructor Attributes/ Strengths: Confident, Cheerful, Dynamic, Organized, Knowledgeable, Passionate

Zobia has a Honour Bachelors of Science degree in Environmental Biology and Masters in Environmental Engineering (specialization water/wastewater treatment, water resources management). She is in the final semester of her PhD studies at McMaster University where her research focuses on development of decision-support system to effectively manage contaminated sites in North America.


Zobia has over 15 years of professional environmental experience working in various capacities at consulting, provincial government, academic, laboratory and hospital settings. Zobia has demonstrated knowledge and understanding in laboratory methods as well as engineering theories, principles, and designs related to water and wastewater treatment. More recently, she has taken a new role as a Manager of Technical Services-Programs and Innovations at World Water Operator Training Inc. (WWOTC), Canada. She has also been a key resource in the recent addition of “wastewater plant simulator technology” applications in many different courses.


Zobia is also a Professor in the School of Engineering Technology at Mohawk College and actively teaching advanced courses and labs in sampling and analysis, water/wastewater treatment, chemistry, environmental science, environmental regulations, solid waste management, and air pollution/climate change. She is also a partner of a consulting firm, Enviro Consulting and Solutions, which provides professional services in the area of environmental science and engineering.


Zobia’s dynamic personality and understanding of what makes a good instructor will be a huge asset in our classes. She is energetic, well-spoken and passionate about working with students. We are happy to have her on our team.

This course is designed for operational staff to gain a good understanding of phosphorus and nitrogen removal systems. This course will assist operators in recognizing operational issues related to nutrients associated with wastewater, and the various ways to troubleshoot and correct these issues.

We will be using a user-friendly simulator model with a comprehensive database of wastewater unit processes allowing users to predict effluent quality under varying conditions to meet nutrient removal, enter characterization data, and run simulations.
