Logo E-KlärWork packages of E-Klär project focus II: Operation

The goal of this project focus is to develop a modular simulation system to model material and energy flows including costs of an entire WWTP forming the basis for process selection and decision-making processes as well as an operational support tool. Project focus II "Operation" is the interface between project focus I "Design" and project focus III "Transformation". The examined innovative treatment processes of project focus I “Design” will be integrated as individual process modules into an enhanced plant-wide modelling approach of the entire WWTP. This plant-wide modelling approach and the individual process modules will be developed as a software-independent version. Within the scope of this project the implementation is achieved using the software WEST. Through the ability of the simulation tool to determine module- and plant-specific characteristic values as input variables for the transformation process, project focus II provides the basis for the long-term modelling in project focus III "Transformation".

Work packages

WP 2.1 Individual process modules

Contact:

Prof. Dr. Karl-Heinz Rosenwinkel, Dr. Maike Beier, University of Hannover, Institute for Sanitary Engineering and Waste Management, Welfengarten 1, 30167 Hannover

Abstract:

The aim of this work package is the development and calibration of individual process modules for each innovative technology investigated in project focus I “Design”. These individual modules will be included in a “library” of an en-hanced modular plant-wide WWTP model. In order to serve the interfaces between different model levels, relevant energy and material parameters as well as cost parameters of the innovative technologies will be included in the individual process modules.

WP 2.2 Overall plant-wide model

Contact:

Ralf Engels, DHI-WASY GmbH, Weinsbergstr. 190, 50825 Cologne

Abstract:

The aim of this work package is the development of a modular overall plant-wide model that links the developed individual process modules and general processes of (1) the process level, (2) the energy level, and (3) the cost level. At the process level, an enhanced process model will be developed. This model integrates the formulated individual modules of the innovative technologies additionally to the already existing standard processes. On the energy level, a consistent energy flow model will be developed that defines all energy flows (thermal, electrical and biochemical stored energy) in the longitudinal section of the WWTP. Furthermore, a cost model will be developed that calculates and visualizes the operating and annual costs for each process unit. In this project, the developed software-independent simulation tool will be implemented in the software WEST.

WP 2.3 Integration of plant concepts

Contact:

Prof. Dr. Karl-Heinz Rosenwinkel, Dr. Maike Beier, University of Hannover, Institute for Sanitary Engineering and Waste Management, Welfengarten 1, 30167 Hannover

Abstract:

The aim of this work package is to model the technical, biological and energy processes of three representative WWTPs of the Ruhrverband by using the plant-wide model implemented in WEST.

WP 2.4 Short-term forecast and control

Contact:

Ralf Engels, DHI-WASY GmbH, Weinsbergstr. 190, 50825 Cologne

Abstract:

In this work package, the developed modular simulation tool will be adapted to be used as an operational support tool (short-term forecast) to determine an efficient energy-optimized wastewater treatment operation mode. For this purpose, exemplary interfaces will be defined and linked to the process control system of a selected representative WWTP of the Ruhrverband.
