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.

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.

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.

SaMuWa - The City – a hydrological system under change

In most cases, urban drainage systems have been designed as static, inflexible systems with a long service period. The results of the „SaMuWa“ project  enable municipalities and wastewater companies to shift from static planning of drainage systems towards adaptive management of the urban hydrological system. Within the project, options for planning and operation have been investigated, which allow to make optimum use of the existing infrastructure under uncertainty and under changing conditions (climate, demographic and structural developments).

ADESBA - A pre-configured general applicable control box for sewer system control (RTC)

Up to now, the development of real time control systems for urban drainage systems represents a rather time and resource consuming task. Based on the fundamental principles of a general control algorithm developed earlier at ifak, universal control modules have been developed – in cooperation with the automation company SEGNO and with the Hanover University – which allow a straightforward and easily-configurable set up of real time control systems. The modules are put in practice in the urban drainage system of Hildesheim.

Development of a software framework for water quality monitoring stations

A software framework for monitoring stations was developed for the company Primodal and the institute modelEAU of the University Laval (Quebec, Canada). 

Modelling of river water quality for the analysis of ecologically critical impacts of wastewater discharges

A current guideline document of the German Federal state of Hesse on the analysis of impacts of waste­water discharges on river water quality was extended by dynamical modelling approaches. At the Technical University of Darmstadt, a methodology, based on the pollutant load model SMUSI 5.0, was developed.

Basic system and modules for design and simulation tools

In this project, a software system for the simulation of dynamic systems and related modules, which can be rapidly and inexpensively used to develop customised software applications, was developed. The software modules will be used to create specialised software solutions for engineering applications. 

(German-Israeli cooperation in water technologies) - Impacts of onsite greywater reuse on urban wastewater systems

Due to shortage of water resources, reuse of greywater is increasingly gaining in importance. This project analyses the impacts of domestic greywater reuse on sewer system and wastewater treatement plant performance. This project combines modelling and simulation with measurements taken from a real case study in Israel.
