The sofTSense project is developing a soft sensor for determining the composition of wastewater.

An essential property of wastewater is its dry matter content (DM content), which has a decisive influence on the operation of wastewater treatment processes. Currently, the DM content of wastewater is determined by analysing samples in the laboratory. However, this leads to a significant time delay between sampling and the result. This delay makes it difficult to adjust operating processes to varying wastewater properties. Real-time provision of the TSS content is therefore an important key to optimised wastewater treatment operation and to saving costs, energy and resources.
