In cooperation with industrial partners, new concepts and technologies for the sustainable treatment and purification of process water for a very wide range of applications are being developed and optimized at the Fraunhofer IGB up to industrial scale. Water treatment and the circulation of process water can thus be carried out economically and sustainably.
Our research and development for the purification of industrial process and wastewater focuses on innovative technologies and integrated system solutions. The aims of these are to avoid or reduce emissions into the environment and to increase the resource-efficiency of the water treatment processes. An ever more important criterion – not least as part of the turnaround in energy policy – is the energy efficiency of the methods used. We therefore develop process-technological energy-optimized methods, work on solutions for the use of renewable energies or waste heat and, when implementing them, take into account that plants can be controlled on the basis of power grid utilization. These factors also result directly in an improved cost efficiency of the processes, so that both ecological and economic requirements can be met in equal measure with our approach.
A comprehensive analysis of the production steps in which water is used always comes first. If water can be saved or the mixing of process wastewater streams that are better treated separately can be prevented, then this is frequently more economical than universal treatment of the process wastewater. In addition, production-integrated water recycling permits greater independence from natural water resources and thus enables production at water-scarce locations – through to complete independence from natural water resources by means of zero liquid discharge.
