SIMBA^# training courses
Training concept

In order to be able to cover the increasingly growing range of topics that can be simulated with SIMBA^# in training modules, a new module system has been introduced. Each module contains a four-hour interactive online training session with three to a maximum of eight participants. A total of five basic modules and 18 special modules are offered. There is a registration list for each module. If there are enough interested parties on the module list, an online date search will be conducted and the module will then be held shortly after. The currently scheduled modules are displayed on the website and other interested applicants can still register for them. The modules offered are presented below.

If a topic is missing, please send us an email at sekretariat@ifak-ts.com and we will try to expand the range of modules.

B.11 – Sewer network control

For many sewer networks, sewer network control is a possible measure to increase the performance of the sewer network at low infrastructure costs. Increasing the performance and flexibility of the essentially static system "sewer network" can also help to better respond to the challenges of climate change. Three approaches are available for designing and describing sewer network controls: (1) formulation of if-then rules, possibly as fuzzy rules, (2) concept of generalised hierarchical controllers, (3) model-predictive control. In SIMBA^# all these approaches can be considered for development, simulation and implementation of a channel network control.

The training module gives an introduction to the basic concepts of sewer network control and explains their application. Finally, hints for practical implementation, e.g. with the open-source tool ifakFAST (Framework for Integrated Automation and Simulation Technologies), are given.

The management of water resources (supply - demand) plays a role in many fields of application, for example the use of rainwater, treated greywater or industrial process water.  The - rather less known - SIMBA^# libraries SUPPLY and NEXUS are available for this purpose. In this course, the use of the modules of these libraries is illustrated with some examples.

B.13 – Digital twins with ifakFAST

The open platform ifakFAST (Framework for Integrated Automation and Simulation Technologies) is intended to support the realisation of solutions aimed at monitoring and optimising the operation of technical processes. The application focus here is in the area of water management plants and processes, especially wastewater treatment plants. The ifakFAST platform has been available as open source since 2019 (https://fast.ifak.eu) and is particularly suitable for the practical realisation of model-based monitoring and control concepts with SIMBA^# ("digital twin").

Gas production in biogas plants is based on complex biochemical processes. Due to the long generation times of the biomass, measures to improve operational management can hardly be evaluated in the real process.

Contents:

B.15 – Modelling of anaerobic digestion at WWTP

Anaerobic sludge digestion is an important process engineering component at wastewater treatment plants. Measures in the section of activated sludge treatment have an impact, albeit with a delay, on sludge digestion and backloading by process water, among other things. This also applies to measures in the sludge treatment section. Models can be used to represent and investigate these reciprocal relationships.

Contents:

• Presentation of anaerobic biochemical model principles
• Model blocks digestion, thickening, dewatering
• Coupling with the activated sludge section
• Control/regulation of process water dosing

B.16 – Cost and resource models (LCA, LCC)

The assessment of water systems usually also includes the estimation of life cycle costs (LCC) as well as impacts with regard to defined environmental indicators (e.g. greenhouse gas emissions, primary energy demand, etc.) (LCA). Here, costs and impacts from construction/material requirements as well as from ongoing operation are to be taken into account. SIMBA^# offers the option to extend the simulation modules with LCC/LCA evaluation modules that perform these evaluations "on the fly" during the simulation.

This course module introduces the use of the LCA/LCA modules and the definition of the corresponding parameters and calculation rules.

Contents:

• Calculation basics, midpoint file of environmental indicators
• Definition of corresponding evaluation scripts

B.17 – Modelling of river water quality

SIMBA^# also allows the modelling of discharges (hydrological and hydrodynamic) and of biochemical transformation processes in rivers. Thus, SIMBA^# can also be used to create models of river water quality. Water quality simulation can play an important role, particularly with regard to the assessment of the effects of discharges from sewer networks and sewage treatment plants, especially with regard to dissolved oxygen and nitrogen (NH3, NH4). Evaluation routines allow the assessment of water quality using the recurrence-duration limits of the British "Urban Pollution Management" manual (similar also in the BWK approach).
