Glossary

Living environment for organisms or space inhabited by a species.

Organic compounds with a ring-shaped structure in which one or more carbon atoms are substituted with a heteroatom (e.g. nitrogen, oxygen).

This procedure was developed by the Fraunhofer Institute for Interfacial Engineering and Biotechnology (IGB). The procedure is characterised by its enhanced efficiency through the use of a smaller -> digester, shorter retention times of the sewage sludge in the digester and a higher biogas yield. With high-rate digestion, the amount of residual sludge requiring disposal is also reduced.

Effect of a specific measure on the properties of a river, e.g. on outflow distribution, flow speed or water levels.

Resistance offered by a medium against the free flow of water. This property depends on the thickness and hydraulic conductivity of a material or ground layer.

Remediation process based on the mechanical properties of fluids.

Study of the mechanics of fluids.

A branch of fluid mechanics dealing with the dynamic, storage and transport processes in hydraulic systems.

The scientific study of water, its spatial and temporal distribution and the associated biological, chemical and physical properties.

Substances that bind moisture from the atmosphere.
