Gillian Burger, MASc

Gillian Burger graduated from McGill University in 2006 with a Bachelor of Civil Engineering and a minor in Environmental Engineering. She then joined Golder Associates in Vancouver as a water resources engineer in the mining waste group. Gillian subsequently relocated with Golder to Johannesburg, South Africa, where she worked as a civil engineer on mine water treatment projects. Following this, Gillian joined Aurecon where she was responsible for the civil and process design of several new and upgraded municipal wastewater treatment plants in Swaziland, Mozambique, Lesotho and South Africa. While with Aurecon, Gillian gained 6 months of site engineering experience at the upgrade of a biological nutrient removal plant in Pretoria, South Africa.

Gillian returned to Canada in 2010 and obtained a Master of Applied Science degree in Civil Engineering from the University of Waterloo in 2012. During this degree, she held the NSERC Graduate Scholarship and Ontario Graduate Scholarship. For her Master’s thesis, Gillian investigated the impacts of thermal pretreatment on activated sludge and developed a pretreatment model. Ms. Burger’s paper based on this work was published in Water Research. During her degree, Gillian also worked as a teaching assistant for two undergraduate engineering courses on wastewater treatment and water quality.

Gillian joined EnviroSim Associates as a process modelling engineer-in-training in January 2013. At EnviroSim, Gillian designs and carries out laboratory experiments to assess the biological nutrient removal capacity of various wastewater treatment plants (phosphorous-release tests, specific nitrification rate tests, denitrification rate tests, etc.). Gillian is also involved in the testing and modelling of wastewater characterization and kinetic studies. Gillian supports consulting projects to analyse process options and assess process capacity. Ms. Burger provides software support to clients, participates in the delivery of EnviroSim training courses and assists with the development of model extensions.

Daniela Conidi, Ph.D

Daniela Conidi is a Process Modeling Specialist with EnviroSim Associates Ltd. Dr. Conidi has over 8 years of experience in conducting wastewater treatment research including chemical precipitation, oxygen transfer performance, kinetic studies, wastewater characterization, co-digestion of municipal primary sludge and food waste, and trace contaminant fate studies.

After graduating from Environmental Engineering at the University of Waterloo Daniela commenced graduate studies at the University of Waterloo under the supervision of Professor Wayne Parker. She obtained the Ph.D. degree in 2015. Areas of interest during this period centered on the effects of solids residence time on chemical phosphorus removal to ultra low levels. During her graduate studies, Daniela also taught a forth year undergraduate wastewater engineering course and worked as a teaching assistant for an undergraduate engineering environmental modeling course.

Dr. Conidi has been with EnviroSim Associates Ltd. since April 2015. Daniela provides process modeling support to clients. In addition, she designs and carries out laboratory experiments to assess the biological nutrient removal capacity of various wastewater treatment plants (i.e. nitrification rate tests), and is involved in the testing and modeling of wastewater characterization and kinetic studies. During her time with EnviroSim, Daniela has also been actively involved in the development and application of the latest version of the BioWin wastewater treatment process simulator. She is also involved in the development of an updated chemical phosphorus removal model in BioWin.

During her undergraduate studies at the University of Waterloo, Daniela obtained one year of work experience as both a Wastewater Research Technician at Environment Canada (Burlington, ON) and an Undergraduate Wastewater Research Assistant at the University of Waterloo (Waterloo, ON). During her time at Environment Canada, she was responsible for the operation, maintenance and optimization of two bioreactors for the co-production of hydrogen and methane gas through the co-digestion of municipal primary sludge and food waste. Daniela was also involved in a research project on the fate of trace contaminants (i.e. nonylphenol adsorption and biodegradation) during wastewater treatment. During her time at the University of Waterloo, she designed and ran an experiment to determine if phosphorus precipitation by iron in wastewater limits microbial activity. She also evaluated a technique to rapidly assess the nitrification rate on biofilm carriers.

Peter Dold, Ph.D.

Peter Dold is the president of EnviroSim Associates Ltd., developers of the BioSim and BioWin dynamic wastewater treatment plant simulators. These are being used worldwide by consulting engineering firms, water companies and municipalities as tools to aid in process analysis, design, control and operation. He also is an adjunct professor at McMaster University in Hamilton, Canada. Dr. Dold is engaged in a range of research projects dealing with wastewater treatment problems and is involved as a consultant in many municipal and industrial projects, including several involving biological nutrient removal (BNR).

After graduating from Chemical Engineering at the University of Cape Town, Peter embarked on a career in environmental engineering. In 1978 he commenced graduate studies at UCT under the supervision of Professor Gerrit Marais, obtaining the Ph.D. degree in 1982. Areas of interest during this period centered on activated sludge process modeling and system control.

In 1983 Peter joined the faculty of the Department of Chemical Engineering at the University of Cape Town as a senior lecturer. This followed a spell of post-doctoral research with Dr. John Andrews at Rice University, Houston. Until he left Cape Town in 1989, Peter conducted research into various aspects of wastewater treatment jointly with Dr. Marais. Other colleagues in the research team included Drs. George Ekama, Mark Wentzel and Dick Loewenthal. The research endeavors of the University of Cape Town Group during this time addressed a range of municipal and industrial wastewater treatment problems relating to activated sludge treatment systems (particularly those designed for nutrient removal), anaerobic systems and aspects of process control. A major focus of Dr. Dold's research was mathematical modeling of activated sludge systems. Between 1983 and 1987 he was actively involved in development of the well-known IAWPRC activated sludge model.

Peter Dold joined McMaster University in 1989 as an NSERC Industrial Research Chair in Environmental Systems Engineering. He continues to expand his research interests in wastewater treatment. Since 1997 Peter has maintained a part-time position at McMaster, and continues to supervise graduate students working on a range of projects with particular emphasis on biological nitrogen and phosphorus removal activated sludge systems. A milestone has been development of a general mathematical model for systems incorporating organics removal, nitrification, denitrification and biological phosphorus removal. This was the first comprehensive mechanistic kinetic model of this type. Dr. Dold is the author or co-author of more than a hundred research papers and comprehensive research reports.

Dr. Dold is actively involved in a range of consulting activities in Europe, Australia and North America, with an emphasis on full-scale biological nutrient removal systems analysis and design. He has hands-on experience in the installation of computer control systems at full-scale and has been consulted as a technical expert in legal matters relating to phosphorus removal wastewater treatment systems.
