Generalised Physicochemical Model (PCM) for Wastewater Processes

May 19, 2023, 10:00 am – 11:30 am in CET
Physicochemical reactions are those which occur spontaneously in conjunction with biochemical processes. These have received limited attention in biochemical reference models, though they have a strong impact on biochemical reactions, as well as directly describing processes such as gas transfer, precipitation, and metal species oxidation and reduction. An effective physicochemical model is critical to wastewater treatment modelling, both at a unit, and plant-wide level.

In this webinar, a general overview on the concept and aspects of physicochemical reactions and their modelling will be presented. The theory of aquatic chemistry as applied to wastewater processes will be described, including aqueous phase equilibria (acid-base equilibria) and the non-ideality due to presence of ions. The theory and modelling of gas-liquid transfer during wastewater treatment will also be tackled. Precipitation modelling will also be discussed, especially focusing on common particulate compounds formed during wastewater treatment such as those formed by calcium, iron, aluminium, carbonates, phosphates and sulfides. Finally, two examples will be given of the plant-wide applications, both industrial and domestic wastewater treatment, of these advanced physicochemical models.

The incorporation of risk and uncertainty in mathematical models to aid the design and operations of WRRF

June 8, 2022, 4:00 PM in CEST
EVENT DESCRIPTION
In the field of wastewater treatment, in spite of many advances over the past 30 years, we are still using design approaches that imply that we work in a well-defined, stationary environment. We typically account for the unpredictable conditions our plant encounter by incorporating generous safety factors in our designs. This often results in overdesigned or inefficient plants. In the current regulatory environment of extremely low effluent nutrient standards, cost pressures, climate change, and energy optimization, a new design approach is required that provides us with an understanding of what are the main sources of uncertainty and quantifies the risk of non-compliance.

The IWA/WEF Design and Operations Uncertainty Task Group (DOUT Group) has been working on the explicit integration of uncertainty in the field of wastewater treatment, for the past 12 years. The group has recently published its Scientific and Technical Report.

This webinar presents the findings of the DOUT Group. The group has presented the key elements of the STR, including such considerations as contract delivery mechanisms and stakeholder perspectives. This webinar focuses on method that we can apply now to include uncertainty analysis in our projects. Specifically, how to identify project specific sources of uncertainty and prioritize them, use of dynamic models to explicitly account for variability, how to incorporate statistical descriptions of major model inputs, how to translate safety factors to Probability Density Functions and how to express model results in terms of statistical watershed criteria.
AGENDA

  • Welcome and Introduction to MIA SG (by Ulf Jeppsson)
  • Introduction to the Webinar and motivation behind the DOUT initiative (Lina Belia)
  • Introducing the principles of uncertainty evaluation (Lorenzo Benedetti)

State-of-the-art in anaerobic digestion modelling

Nov 22, 2021 9:00 AM in CET
EVENT DESCRIPTION
Anaerobic digestion (AD) is a key technology in wastewater/waste treatment and valorisation facilities. AD has been used for decades to reduce the volume of sewage sludge from WWTPs, transforming it into biogas (usually recovered as energy via cogeneration) and into a nutrient-rich effluent (digestate). Novel developments in the field, and public policies favoring its implementation, are causing a substantial increase in the number of AD plants worldwide. Within this expansion, the variety of organic streams to be valorised via AD is increasing rapidly. Being AD a mature technology, AD modelling is a well-established field, with the IWA ADM1 being the most well-known and applied model. In the last few years, the increasing complexity of WWTPs (together with the paradigm change towards waste resource recovery facilities) and the expanding AD applications, have called for the development of new models, as well as the modification of existing ones. This webinar aims to:

  • present the current state of AD;
  • present the state-of-the-art in AD modelling (focused on the ADM1 and its most recent modifications);
  • discuss the current state of AD control strategies, and how they will be crucial for the optimisation of AD plants.

TARGET AUDIENCE
Engineers designing and working with AD plants, process modellers (including AD modelling and integrated modelling of WWTPs where AD of sludge is present), process scientists researching AD, developers of model-based decision support systems for AD reactors, plant operators, researchers/engineering working on AD plant monitoring, control and optimisation.

Modelling wastewater treatment resilience for improved decision making and resource recovery

Oct 21, 2021 4:00 PM in CEST
EVENT DESCRIPTION
Many decision-making levels are made for wastewater treatment processes, from high-level planning to the operational worker maintaining wastewater treatment assets. Modelling outputs for decision making at both levels require very different approaches, particularly when innovative or novel processes are used for resource recovery. At a process engineering level, resilience and interventions are managed through real instrument data.
This webinar aims to present:

  • The use of conventional biological modelling methods, and real instrument data to charecterise WWTP resilience and the limitations of modelling resilience of wastewater treatment processes and infrastructure.
  • The challenge of modelling decisions at the wastewater plant level and high-level decision-makers when considering the recovery of resources from wastewater
  • Novel modelling methodology for the visual representation of resilience in an interoperable format

TARGET AUDIENCE
Asset resilience specialists, asset managers, process engineers, process modellers, process scientists, data visualisation specialists, decision modelling specialists.

Advancements on N2O modelling in water resource recovery facilities

Sept 21, 2021 10:00 AM in CEST
TARGET AUDIENCE
Process modelers, utility managers, and technologists, consultants, academics and modelers with interest in carbon footprint mitigation of WRRFs.

DESCRIPTION
Wastewater treatment plants are large contributors to greenhouse gas (GHG) emissions. This comprises both direct and indirect emissions of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Direct emissions are mainly related to the biological treatment processes. N2O emitted during nitrification/denitrification stages is the most significant direct form of emission while indirect emission is mainly associated with the energy consumption of the plant for which aeration is one of the largest contributors. Mathematical modelling is a widely used tool for the optimization of wastewater treatment plants, mostly in terms of effluent qualities. Only recently the focus of this has been extended to include carbon footprint minimization targets. However, the question remains to which extent models are useful to evaluate, predict and/or mitigate N2O emissions from wastewater treatment processes. In this regard, the IWA Task Group on GHG Emission has a broad objective of understanding and modelling the processes responsible for major contributions to GHG emissions in WRRFs and sewer networks. In this webinar, we are focusing on the history and state-of-the-art studies on N2O modelling as well as recent advancements in the use of mathematical modelling for prediction of N2O emissions in WRRFs and how models can help plant managers in adopting appropriate control and mitigation strategies.

SPEAKERS

      • Introduction to MIA SG and the Webinar: Ulf Jeppsson, Lund University, Sweden & Liu Ye, University of Queensland, Australia.
      • History and state of the art of N2O modelling: Mathieu Sperandio, INSA Toulouse, France

Hybrid models in wastewater: merging mechanistic with data-driven

Nov 10, 2020 4:00 PM in CET
TARGET AUDIENCE

Process modelers, Utility managers, and technologists, consultants, academics and modelers with interest in data science.

DESCRIPTION

Recent literature shows examples of modelling approaches for the integrated urban wastewater system (UWS) operation and asset management. Such examples range from classical theory-based approaches, using mechanistic or empirical knowledge, to theory-free data-driven models using big data.

On one hand, mechanistic models have been extensively used for process design and optimization. However, building the perfect mechanistic model is only possible for the simplest systems, consequently not for biological processes. The resulting limited prediction capability is a limiting factor in using them for real-time decision-making. On the other hand, “pure” big data models exist but remain isolated initiatives in the academic sector.

The close integration of mechanistic models with Big Data processing and learning techniques has the potential to transform how the day-to-day integrated operation of UWS is currently being done.

In this webinar, we will showcase the potential of hybridized mechanistic and data-driven models in the wastewater sector by presenting three existing initiatives that are working towards integrating both paradigms into hybrid models.

The duration of this webinar will be 60 minutes.
LEARNING OBJECTIVES

The participants will learn about:

      • Understanding the advantages and drawbacks of mechanistic and data-driven models,
      • Getting familiar with model hybridization through practical examples, combining mechanistic and data-driven models to leverage the strength of both approaches.

KEY MESSAGES

      • Mechanistic and data-driven models have both their advantages and drawbacks. Neither of them can tackle all the modelling challenges of the future.
      • Combining mechanistic and data-driven models allows to leverage the strength of both approaches

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).
