Municipal 4.0 - Customized Services for the Water Management

In this cooperative research project, web-based platforms, application tools based on them and corres­ponding business models are developed. For municipal operators of water management systems, such as sewer networks, pumping stations, stormwater tanks and wastewater treatment plants, innovative applica­tions of IoT (Internet of things) / Indstrie 4.0 concepts are currently being created and will pave the way for the digital transformation.

Scenarios of future developments of Kigali, capital of Rwanda - ifak contributes to scenario workshop

Scenarios of potential future developments of Kigali, the rapidly growing capital of Rwanda in East Africa, were the topic of a scenario workshop held on 25 October in Kigali. ifak contributed significantly to the preparations of this workshop, which was organised by TU Berlin within the BMBF-funded project "Rapid Planning". After a short introduction into the context of the "Rapid Planning" project, group discussions highlighted current and potential future developments in the water, wastewater, energy, waste and food sectors.

OptiBelD - Joint Project: Energy efficiency and process optimization of the activated sludge process based on an integral process-fluid flow simulation - Sub-Project: Development of an integral process engineering simulation environment

In Germany, wastewater treatment plants are the largest municipal electricity consumers. A study by the Federal Environment Agency (Haberkern, 2008) indicates that in the case of a pure energy optimization, an average electricity saving of 10 to 20% of the total power requirement can be expected. The aim of the project is the holistic optimization of the biological treatment stage of wastewater treatment plants by a plant-specific optimization of the processes technology, the selection of energy-efficient machine technology and the development of intelligent control concepts. 

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. 

German-Israel cooperation on water technologies - ifak scientist at a project meeting in Haifa

In the second week of november, Dr Schütze of ifak is attending a project meeting with ifak's cooperation partner in Israel. In this workshop with Prof. Friedler of Technion - Israel Institute of Technology and his research group, this scientists are discussing the results achieved so far in the CLUWAL project, which is funded by German Ministry of Education and Research (BMBF) and the Ministry of Science and Technology (MOST) of the State of Israel. In this bilateral research cooperation,simulation-based methods for the assessment of urban water system are developed.These will allow municipalities and water authorities a prudent management of their water systems, by assessing various technological options according to social, ecological and economic criteria of sustainability. Of particular importance in this project are rainwater and stormwater harvesting, as a means of saving precious water resources.

Biological and energetic simulation of the wastewater treatment plant Aschersleben

In the context of this work a model of the wastewater treatment plant in Aschersleben was developed. The model includes the mechanical and biological treatment and the (fluctuating) energy demand of the most important energy consuming devices.

This project aims for a verified model of the plant with a subsequent energetic optimization by considering the individual devices. The model will be simulated with various optimization strategies and will as well take into account the fluctuating load of the plant.

KURAS - Concepts for urban stormwater management and wastewater systems

The project KURAS has developed  sustainable concepts to deal with waste water and rain water in urban regions based on clima change and demographical development assumptions. Within this project, ifak has modelled, simulated and analysed various measures to improve the behaviour of waste water treatment plants in overload situations (more frequent heavy storm events) as well as low flow rate or load situations expected e.g. during more dry sommer seasons.

nidA200 - New sanitation concept for decentralised waste water and bio waste treatment incoperationg anaerobic digestion and algae production

The parish Hille is one of the greatest area communities of Germany and has a central wastewater treat­ment plant. Due to new land use plans and new construction areas, Hille wants a new wastewater treatment concept that reduce the high infrastructure costs of the great area. Because of the nearby recreation and water protection areas, including a sensitive moor, the cleaned wastewater has to accomplish high quality demands.

NoNitriNox - Design and operation of energy efficient waste water treatment plants and avoiding environment damaging emissions

The project aimed to describe and to model the potential production of greenhouse gases like N2O or the potential release of nitrite from waste water treatment plants as result of control concepts aiming at energy minimisation. The developed model will be used to analyse and develop control concepts aiming on minimi­sation of effluent loads including GHG emissions and nitrite and to minimise energy consumption at the same time.
