The SIMBA simulation system allows the holistic consideration of sewer system, wastewater treatment plant, sludge treatment and rivers. All components necessary for a thorough analysis of the constituent subsystems, including their interactions, are now available within the same simulator. SIMBA can be applied for a wide variety of tasks in engineering practice and in research and education:  

• Design of wastewater treatment plants (WWTPs), considering all process options including control
• Optimisation of process design and operation of existing WWTPs
• Analysis of process water management, sludge treatment, energy demand
• Simulation of rainfall runoff, flow and quality processes in urban areas
• Design of storage structures
• Strategies for sewer system operation (real time control)
• Scientific analysis of pollutant transport and biochemical transformation processes
• Prediction of chemical and biological substances in rivers
• Simulation of the interactions of runoff, wastewater treatment and river water quality for scenarios with and without control

Features

• A large selection of activated sludge models
• Modules and libraries for typical process steps
• Custom biochemical transformation models
• A wide range of tools aiding in modelling, simulation and evaluation
• Hydrologic and fully hydrodynamic modelling approaches for sewer systems
• Calculation and presentation of resource and energy fluxes within the entire system
• Supports the planning of wastewater treatment plants conform to A131 of researchers` simulation group
• Modelling of control systems in a PLC programming language (IEC 61131 ST)
• Improved approach for the modelling of transport of substances into the sewer system and rivers (Lagrange)
• Library for interactive simulation: blocks for manual control, animated visualization

Grafische Bedienoberfläche 

SIMBA is based on Matlab®/Simulink™ of The MathWorks Inc. It can be used under Windows 2000, X, Vista and Windows 7 operating systems. With the origins of its development at ifak e.V. Magdeburg (Institut f. Automation und Kommunikation) dating back to 1994, SIMBA is used today worldwide for the design and operation of wastewater systems and for education and research.  The features of SIMBA can be accessed by buttons, extensive graphical block libraries and menus. 

Libraries 

The model foundations used by SIMBA, e.g. the Activated Sludge Models, Anaerobic Digestion and pollutant transport and conversion models, are provided in open format, using a symbolic notation. These can be accessed and modified using a model editor. Model blocks can be linked conveniently, thus allowing the holistic consideration of wastewater processes. Since SIMBA is an open modelling system, also new models and functions can be easily added by the user. The model foundations in SIMBA include: 

• Activated Sludge Models (ASM1, ASM2d, ASM3, ASM1sbr, ASM1tm)
• Sludge treatment (Siegrist, ADM1)
• Sewer system and river water quality models (Qsimp, Lijklema)
• SBML Model exchange format: SIMBA supports SBML (Version 2) model description language, which has been developed in the area of systems biology for the representation of metabolic processes.
