Reference excerpt

Imre Takács is a Hungarian-Canadian-French environmental engineer and process engineer. He is a founder and President of Dynamita SAS, based in France, and developer of process simulators and dynamic models for wastewater treatment plants. Takács has made contributions to environmental engineering, with a particular focus on biological and physico-chemical water treatment processes. He is known for the development of modeling and software solutions for water and wastewater plant control and has overseen projects aimed at implementing progressive technologies in full-scale wastewater treatment plants. He has authored book chapters for organizations, peer-reviewed journals and his paper on the dynamic process model for thickening and clarification was selected as one of the top ten most influential papers for the Water Research journal in the past 40 years. He is the recipient of the 2019 Fuhrman Medal for Outstanding Academic-Practice Collaboration from the International Water Association (IWA). Takács has contributed to the development of industry process software, including GPS-X from and Biowin. Additionally, he introduced Sumo, a third-generation wastewater process modeling software. Takács initiated the WWTmod (later WRRmod) conference series for modellers. He is the founder and first director of the MEGA workgroup in Municipal Resource Recovery Design Community (MRRDC) at WEF. He has been involved in various IWA groups, such as the Task Group for Good Modelling Practice (GMP) and Good Biofilm Reactor Modelling Practice, and has been serving on many scientific committees including the scientific committee for the IWA Specialised Conference on Design, Operation, and Economics of Large Wastewater Treatment Plants.

Education Takács obtained his bachelor's degree in 1978 from Budapest University of Technology and Economics, specializing in Industrial Food Processing Engineering. In 1980, he earned a master's degree and completed his Doctor of Technology degree in 1986, both in Environmental Bioengineering from the same institution. Subsequently, he continued his doctoral studies, culminating in a PhD in Environmental Technology from Ghent University in 2008.

Career Takács started his professional career in 1980 as a Project Engineer at the Water Quality Institute (VITUKI, Hungary), where he served until 1988 while also maintaining a position at VIZITERV in 1983. Following this, he assumed the role of Head of R&D at Hydromantis, and from 2002 to 2008, he served at EnviroSim Associates, followed by two years where he was assigned a managerial position within their European subsidiary office. In 2010, he founded Dynamita, a software and process modelling company and has since served as its CEO. Takács held the role of Project Manager for numerous projects including for DCWATER's Blue Plains plant and HRSD's Nansemond plant at Norfolk. Takács is a Water-Energy Nexus (WEX) fellow with the University of California at Irvine (UCI). He held a part-time professorship within the Geology department from 1994 to 2002. Prior to that he worked as a Research Engineer at McMaster University between 1988 and 1991.

Contributions Takács has been involved with projects of environmental software development, process optimization, and advanced control systems. He played a key role in the development of environmental software packages like VNP, GPS-X, BioWin and SUMO. His work extended to the Blue Plains facility, where he devised characterization methods for optimizing carbon source dosing and anaerobic digestion modeling.

Research Takács developed new concepts in process modeling including settling, chemical and biological phosphorus removal, side-stream treatment, carbon capture for energy recovery, biofilms, granules and granulation, equilibrium chemistry, natural and engineered precipitation, such as for nutrient recovery.

Wastewater treatment models Takács' research on wastewater treatment modeling has emphasized the improvement of modeling techniques and data quality. He introduced a dynamic model for the clarification-thickening process, employing experimental data from various experiments. In 2008, he critically assessed various model concepts for nitrite modeling in processes like two-step denitrification, anaerobic ammonium oxidation, and phosphorus uptake, highlighting the need for further development. Furthermore, he authored a book chapter in Biological Wastewater Treatment: Principles, Modelling, and Design, which focused on final settling tanks to emphasize the practical aspects, design, and operation of phase separation units. He also contributed to a collaborative effort proposing a standardized notation system for naming state variables in biokinetic models, aiming for consistent rules across existing and future models. In a paper published for the Water Environment Research, his work involved the development of a phosphate complexation model which utilized geochemical reactions on hydrous ferric oxide (HFO) surfaces to comprehend the process of chemically mediated phosphate removal. Takács has conducted research addressing the critical issue of data reconciliation in wastewater treatment modeling, offering an approach for obtaining reliable data sets for model-based studies. He investigated the sensitivity of nitrite transfer between aerobic and anaerobic ammonia oxidizers highlighting the significance of selecting an appropriate sludge retention time. Alongside fellow researchers, he introduced a dynamic physico-chemical model for chemical phosphorus removal in wastewater treatment. This model incorporated chemical equilibrium and physical precipitation reactions, effectively simulating observed bulk dynamics in terms of pH.

Worked examples

Example 1 — a first encounter with Imre Takács

Start with the simplest possible case. Write down what Imre Takács claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Imre Takács before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Imre Takács ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Imre Takács

In research: Imre Takács appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Imre Takács in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Imre Takács is common in secondary-school and first-year university syllabi. It links to neighbouring topics Budapest University of Technology and Economics alumni, Environmental engineers, Ghent University alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Imre Takács outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
