Work Package 4
Drinking water extraction and purification

Responsible
Technische Universität Ilmenau, Institute for Automation and Systems Engineering, Dept. Simulation and Optimal Processes (TUIlm)

Participating
Fraunhofer Application Center Systems Technology Ilmenau, Dept. Water (FhAST) Drinking water and ground water extraction through deep wells as well as its purification; estimation of quantity and quality for sustainable population and economic growth (Technical University Ilmenau, Faculty of Computer Science and Automation (TUIlm) & Fraunhofer Application Center System Technology Ilmenau, Department for Water (FhAST)).

Objectives
The main goal of this work package consists of the development of a sustainable control strategy of drinking water extraction concerning quantitative and qualitative aspects including drinking water treatment under consideration of technical measures (groundwater monitoring, pumping, and treatment), of natural and economic conditions, efficiency, influences on the society (e.g. quality of life), and the coupling to the other work packages.

Outgoing from the current situation of drinking water extraction from groundwater the main focus of the work is on modelling of the groundwater system and its simulation – always with regard to a model-based computation of control decisions using simplified control models by application of certain methods of systems engineering including optimisation techniques. The model will be developed together with the School of Geology and Petroleum Engineering, MUST Ulaanbaatar, Prof. Batsukh, Mrs. Buyankhishig, by means of registered data in the model region Darkhan and be calibrated (by recorded groundwater level data of four wells since June 2007). The results of this part of the work package will be control regimes of the sustainable use of groundwater in terms of upper limits and its time variability concerning the coupled drinking water distribution process.

The Fraunhofer Application Center Systems Technology contributes to this work package by calculation of optimal control strategy in dependence of water quality and quantity as well as the consumtion behaviour of the customers in the distribution network (optimal resource distribution).
