The Warm and Clean City
Wastewater treatment is an important function of society, and one that confronts many challenges. The project, “The Warm and Clean City” is developing and testing new total solutions for the world’s wastewater treatment plants. The solutions are resource-efficient and facilitate utilizing substances in the wastewater for generating saleable products, while at the same time closing the water and nutrient loops.
Two concepts for wastewater treatment have been produced in the initial project, which will be tested and evaluated: ”energy-positive treatment” and “compact treatment”. A system analysis of the results will calculate operational, economic and environmental consequences and investigate the possibilities for system integration in existing wastewater treatment plants.
The project will develop new techniques, combining and applying different methods for improving the treatment of wastewater, while at the same time producing clean water, biogas, algae products and useable nutrients. Utilizing waste heat from industries, new types of membranes and cultivation of algae facilitates better methods than those of conventional wastewater treatment.
The project is in part financed by VINNOVA, with the City of Lund as the grant receiver. Markus Paulsson is the project leader. VA-teknik at Lund University, together with VA SYD, via Sweden Water Research, participates in the continuation of the project, “The Warm and Clean City”.
