EXPOPLAN - Development of a design software for waste water treatment plants in warm and cold regions

The developed design software implements the results of the finalised project EXPOVAL. As a result of this predecessor project design and operational advises for treatment plants in warm and cold regions are available as a DWA-Themenband.

CLUWAL  - Closing the urban water loop - Integrated urban water and wastewater management for increased sustainability

In the research project CLUWAL, researchers from ifak, together with researchers at Technion in Haifa/Israel (research group of Prof. Eran Friedler), are developing simulation-based evaluation methods. These will allow municipalities and water authorities to assess their water systems and related measures according to social, ecological and economic criteria of sustainability, thus allowing a prudent management of the precious water resources. This project allows ifak, a world-renowned centre of competence in modelling and simulation of water systems, to extend its portfolio. Research within the CLUWAL project, based on an integrated water cycle-based approach, will also support the New Urban Agenda of the United Nations, as it has been adopted in autumn 2016 in Quito/Ecuador.

WavE - Joint research project WEISS: Efficient operation of cooling water circuits by integrated desalination at the example of the steel industry

The steel production process has a high demand for cooling water and chemical products to prevent mineral and biological contamination in the cooling water circuit. By adapting the use of biocide chemicals and fresh water intake to the blow down water treatment and the actual demand, blow down water could be reduced by a half. The complex representation and optimisation of the overall water system with fresh water input, cooling water circuit and blow down treatment with desalination processes and chemical dosage require the use and development of a simulation tool.

SAmpSONS - Simulation and Visualistion of resource fluxes in new and alternative sanitation systems - Support in the analysis of their function, costs and resource balance

New and alternative sanitation systems are more and more within the focus of attention also in Germany, considering reduced availability of resources, decreasing water consumption and demographic and climatic changes. Such systems aim at reuse of limited resources (e.g.nutrients) and at a more sustainable management of water resources. Discussions about these concepts often get very emotional. Planners and authorities often are reluctant to introduce such systems. This is partly due to lack of understanding of the potential such systems might be able to offer.

MENDEL - Minimal load of power grids through charging operations of electric busses

Fully electric buses in public transportation are currently forced to intermediately charge their batteries in order to overcome their daily mileage of 250-300 km. If in the future a transport company operates a bus fleet with 100 and more electric busses, the maximum power supply of the local distribution grid exceeds quickly when several busses would be charged simultaneously. As a result, transport companies will require own transformer stations directly connected to the medium voltage grid. Planning and building such stations is time consuming and costly. Moreover, charging many buses simultaneously may also cause high peak loads resulting in a correspondingly high capacity charge of the transport company.
