Resource-recovering Wastewater Systems

To achieve sustainability, the wastewater sector is currently transitioning from treatment and discharge to recovery of resources that can be found in wastewater.

Framework for Sustainability Analysis
Photo: Magnus Arnell

At RISE, we apply a system-wide sustainability analysis including society, organization, technology in order to assess sustainability of wastewater systems. The system analysis includes a wide set of criteria: i.e. societal, health, technology, environmental and economy, using models and the latest research. The systems assessed by RISE to date include, among others, novel wastewater solutions and technologies to save and recover resources, such as water, energy and nutrients, e.g. source separating wastewater systems or nutrient recovery processes at WWTPs.

Testbed for small scale wastewater treatment

Nationally unique, as the plant is connected to one of the few sewers with a separate stream of toilet water (black water). This allows us to mix and adapt wastewater to customer needs. Our test bed is partially underground, which…

Sustainable waste water treatment plant

For a small municipality with a high proportion of seasonal residents a traditional waste water treatment plant can be unviable from a sustainability and economic perspective, while the alternative of land-based treatment entails …

Modelling of Wastewater Treatment Plants – Barrier Buster

Due to urbanization, stricter environmental regulations and climate change, Swedish wastewater systems face large re-investments in the coming years. Dynamic process models provide the possibility to evaluate performance and provi…
