Natural low-cost bioprocesses for wastewater and sludge treatment

We study natural systems for wastewater and sludge treatment. These sustainable technologies and low-cost bioprocesses do not require energy for operation. They include ecotechnologies like waste stabilization ponds and constructed wetlands. The main purpose of our research is to understand the mechanisms of pollutants removal in order to improve the design, construction and operation of these systems. By combining fundamental and applied research, we look at the following topics: hydraulic and hydrodynamic aspects, design parameters, remote control systems, pollutant removal mechanisms, nutrients and emerging pollutants removal, greenhouse gas emissions, life cycle analysis and economic evaluation.

Sludge treatment in reed beds represents a novel alternative to conventional sludge treatment, minimizing the environmental impact of sludge management with a low-cost technology.
