Today's gold standard for wastewater management is a sewer system with a centralised wastewater treatment plant. However, this system has its limits, because it requires large amounts of water and an extensive infrastructure. An alternative are small, highly efficient decentralised reactors, which allow a more flexible wastewater management. We develop processes, which can be used for such wastewater treatment plants. We use the following three principles as guidelines:
Separation at the source: Waste streams with different compositions should be treated separately according to their properties.
Decentralisation: The waste streams should be treated as closely to the source as possible, thereby minimising resource consumption and environmental pollution.
Resource recovery: The treatment should focus on recovering the resources contained in the waste streams.
