Disinfection modelling

Oct 24, 2019 4:00 PM in CEST

Utility managers and technologists, consultants, WRRF and drinking water plant designers, as well as academics and modellers with interest in disinfection of water and wastewater.


  • Advanced tools are available to support disinfection process design
  • When multiple design objectives are to be met, process dynamics must be taken into account and appropriately controlled;
  • Risk-based methodologies are being developed in order to move from a deterministic to a probabilistic integrated disinfection design framework

The duration of this webinar will be 60 minutes.


The participants will learn about:

  • Main modelling methodologies for disinfection design, optimization and scale-up
  • Established integrated modelling frameworks for designing and optimizing disinfection for multiple treatment objectives
  • Emerging modelling methodologies to assess disinfection under water quality variability and uncertainty

Computational Fluid Dynamics: applications and good modelling practice

Feb 5, 2019 4:00 PM in CEST


Utility managers and technologists, consultants, WRRF and drinking water plant designers (= the problem owners) as well as academics and modelers in general. This webinar is meant to be accessible and relevant for both experts and non-experts in CFD. The emphasis on case-studies gives non-experts a hands-on introduction to CFD, while experts expand their horizon.


This webinar demonstrates the application of Computational Fluid Dynamics in the context of (waste) water treatment. Three parts are foreseen:
Introduction: what is CFD and which options are available to answer which type of practical questions? This intro is meant for non-experts, and kept short in order not to lose more experienced participants from the start.
Applications. A set of case-studies (both water and wastewater) from practice illustrating the added value of CFD in decision making.
Good Modelling Practice. The current consensus on GMP with regards to CFD.

The duration of this webinar will be 90 minutes.


The participants will learn about:
… the importance of hydrodynamics/mixing in different (waste)water contexts and which type of questions need CFD to be answered properly.
… the current state of the art in (waste)water related CFD potential
… the power of CFD in decision support by means of practical examples
… Good Modelling Practice to soundly conduct a CFD project
In essence, participants will get a new view on this relatively new modelling tool in the context of (waste)water, and be able to place this knowledge in the broader context of their daily occupation.

New advances in Enhanced Biological Phosphorus Removal (EBPR) Modelling

Jul 9, 2018 4:00 PM in CEST


Modellers and practitioners, consultants, researchers, software developers, plant managers/operators of water resource recovery facilities.


Following the 6th IWA/WEF Water Resource Recovery Modelling Seminar (WRRmod2018), the enhanced biological phosphorus removal (EBPR) session was elected through an online survey of IWA Specialist Group on Modelling and Integrated Assessment (MIA) members for a webinar.

Two new models for EBPR systems were presented, one based on the metabolic approach and the second one based on Activated Sludge Model (ASM)-type model approach. Both models aim to overcome shortcomings of existing models that fail in predicting the behavior of EBPR processes under process upset conditions and of side-stream EBPR higher performance.

The two models are critically reviewed by practitioners to provide a constructive discussion on the newly implemented processes and usability of the models.

The duration of this webinar is 90 minutes.


Learning about the main activities and areas supported by IWA MIA SG, especially in the topics of enhanced biological phosphorus removal modelling. The specific learning objectives are:

– Learning objective 1: Gain an overview of existing models for EBPR systems and their limitations
– Learning objective 2: Gain an overview of most recent research in EBPR model development
– Learning objective 3: Understand what the complexity level, applicability and limitations of the new developed models are, and in a general way what are the difficulties in developing new models.

Modelling Resource Recovery: State of the art and future challenges

Feb 6, 2018 4:00 PM in CEST

With the paradigm shift from “wastewater treatment plants” to “water resource recovery facilities”, wastewater is now considered not just as something to be treated but as a resource from which benefits and products can be recovered.

In this webinar, a general overview on the concept of water resource recovery facilities is presented, wherein examples of existing resource recovery technologies will be discussed. A number of existing models is revisited to determine what is missing in terms of model structure. The webinar aims to present current efforts to model these processes, with particular attention to technologies related to carbon and nutrient recovery. There is also a discussion on model uncertainty which will potentially guide resource recovery processes’ modellers and model-users alike.

THE WEBINAR WAS HOSTED BY Ingmar Nopens (Ghent University, Belgium) and Ulf Jeppsson (Lund University, Sweden).

Modelling and Integrated assessment: Overcoming data issues and barriers to integrated modelling in practice

Sep 26, 2017 4:00 PM in CEST

This webinar discusses two common challenges in the application of modelling and integrated assessment.

The 1st topic of this webinar “Overcoming data issues in process modelling” discusses the challenges related to recognizing and obtaining good quality data. In fact, modellers spend a significant part of their time on data screening and collecting additional measurements instead of developing new models and providing solutions for process optimisation. Specific attention was paid to typical fault patterns and the selection of proper tools for their detection.

The 2nd topic “Integrated modelling in practice” aims to discuss the barriers that are preventing the application of an integrated model for decision support in urban water management. The webinar focused on the diverse nature of these barriers, provided some examples of potential strategies and introduced a systematic way to increase receptivity towards integrated models.

THE WEBINAR WAS HOSTED BY Ingmar Nopens (Ghent University, Belgium) and Ulf Jeppsson (Lund University, Sweden).


All of them are members of IWA specialist group on Modelling & Integrated Assessment


COST Action Water 2000 e-course

In the framework of the COST Action Water 2020 (Conceiving Waste Water Treatment in 2020 – Energetic, environmental and economic challenges (ES1202)), an e-course on Micropollutants in Water has been prepared. The e-course is available here.

Advanced course on Modelling of Integrated Urban Drainage-Wastewater Systems

Wednesday 6th – Saturday 9th September 2017, Prague, Czech Republic.
DTU Environment and modelEAU, Université Laval, in collaboration with the Czech Technical University (Faculty of Civil Engineering),  are happy to announce the fourth edition of the advanced course on Modelling of Integrated Urban Drainage-Wastewater Systems.

After the previous editions held in Copenhagen (Denmark), Quebec City (Canada), and Lyon (France), this year the course will be held in Prague (Czech Republic) in the days before the 14th ICUD conference ( This will give the opportunity to all the ICUD participants to follow the course (but you do not need to attend ICUD to follow the course).

The physical part of the course will be held at CTU campus from Wednesday 6th (afternoon) to Saturday 9th September. The course will also have an e-learning part, starting on 14th August.

The course is targeted at practitioners,  PhD students, and researchers modelling the elements of integrated Urban Drainage-Wastewater systems – drainage network, wastewater treatment plants, receiving water bodies. The course consists of an overview of state-of-the-art tools for integrated modelling of urban drainage and wastewater systems, simulation exercises based on the WEST® software, and examples of application of integrated approaches for improving the environmental status of natural water bodies.

Students will be awarded a total of 2.5 ECTS by the Technical University of Denmark after the completion of the course.
