Buyer profile: Aarhus Vand

Aarhus Vand’s goal is to make Marselisborg ReWater the world’s most resource efficient Waste Water Treatment Plant (WWTP). The ambition is to not only meet the current and future requirements within purifying of water, but to be a leading player in securing an optimal aquatic environment in Aarhus Bay benefitting both humans and nature. Marselisborg ReWater will not only be treating wastewater, but also produce energy and nutrients from the wastewater to an unprecedented extent. The ambition is to have an energy neutral supply of drinking water and wastewater treatment. Marselisborg ReWater will be extracting and utilizing valuable resources from the wastewater. Resources that are today classified as waste matter and needs disposal, but can be used for ‘green’ power and heating or fertiliser. By utilising the resources, they we can reduce the costs of wastewater treatment by sale of electricity, heat and biogas, extraction of resources such as heavy metals, phosphorus and plastic, or cultivation of crops that both cleans and can be used for fuel or industrial production.

Many technologies in developing Marselisborg WWTP into a resource plant are already known and in use in Aarhus Vand’s existing WWTP’s. Other technologies are yet to be developed. Therefore, they have identified 15 innovation challenges that have to be addressed early in the process, making sure that they will get a comprehensive input of technologies and solutions to choose from. The approach is to openly invite companies, manufacturers, research institutions, and alike to offer their products, services, knowledge, and know-how into the process by having them answer how they would solve one (or more) of the innovation challenges. (Read more about the challenges: http://www.aarhusvand.dk/en/international/new_solutions/marselisborg-rewater/innovation_challenges/). More specifically Aarhus Vand are looking for solutions to the following innovation challenges:

#1: How do we best exploit the central location in Aarhus and the site-specific potential of Tangkrogen?

#2: How do we create a cleaner harbour and Bay of Aarhus while at the same time treating the water from a growing city?

#5: How do we avoid odor problems when the plant is located in an urban context?

#9: How to develop a fully automated wastewater treatment plant, where no people are in contact with untreated and dangerous material?
