In a chemical plant, process water is required at numerous points: for heating or cooling, to produce steam, as a solvent and reaction medium, or simply for rinsing. This is one of the reasons why almost every major chemical plant is located on a river. The water taken from the river is pre-treated to the desired process specification in a central plant. A large part of the water is used only once, then post-treated in a central plant and returned to the river.

However, the pressure to conserve water as a resource is constantly increasing. Furthermore, companies are increasingly interested in keeping even small amounts of toxic or non-degradable substances out of the environment. This is leading to a rethink: Our customers increasingly want to implement decentralized plants for recycling low-contaminated streams as well as for the treatment of partial wastewater streams. Our expert teams adapt these specialised systems to the specifics of the respective location. H+E uses its complete portfolio of physicochemical, biological, and thermal processes to pre-treat river water and produce demineralised water, to treat recyclable wastewater and to process wastewater streams with low and high levels of pollution.
