A story of entrepreneurship, know-how, and vision

Innovation in cleantech solutions

Aquarden was founded in 2005 inspired by the results of an EU-funded research project demonstrating the remarkable performance of SCWO for the treatment of wastewater. Since then Aquarden has progressed continuously towards commercializing its SCWO system, which received the European Business Award for the Environment in Denmark in 2016 for its significant contribution to a sustainable development and innovation.

Provider of total solutions

Today, Aquarden uses its expert wastewater knowledge to deliver cleantech solutions for solving the toughest wastewater challenges. We deliver consultancy, turnkey systems, and services – all customized to meet customers’ specific requirements. The SCWO system, SuperOx® is our pride and flagship and often the central technology in our solutions. But wastewater streams and customer challenges and needs are seldom identical and thus call for different approaches. That is why we also offer a range of third party technologies.

World-class production and research facilities

Aquarden is headquartered in the town of Skævinge, a small village situated north of Copenhagen, Denmark. We have recently renovated our factory building to accommodate our growing number of projects and activities. It now includes fully equipped production halls, a state-of-the-art chemical laboratory, administration, and R&D facilities for our expanding team of experts.

“At Aquarden we believe all our planets man-made water problems can be solved sustainably today.
