Aquarden Technologies ApS
About
Aquarden Technologies ApS is a Danish cleantech company founded in 2005 and headquartered in Skævinge, Denmark, specializing in supercritical water oxidation (SCWO) technology for destroying persistent and toxic pollutants in industrial wastewater. Their SuperOx system operates above water's critical point (374°C, 221 bar) to fully mineralize organic contaminants including PFAS, pesticides, pharmaceuticals, chemical warfare agents, and explosives into CO2, water, nitrogen, and benign mineral salts. The system runs entirely on electricity with no fossil co-fuels, processes up to 5 tonnes per day per unit in a continuous-flow modular configuration, and reuses oxidation heat to pre-heat incoming waste streams. Aquarden's PFASinator variant specifically targets concentrated PFAS waste streams, achieving greater than 99.999% destruction efficiency for spent ion-exchange resins, activated carbon, AFFF, foam fractionation foamate, and membrane concentrates. The company won the European Business Award for the Environment (Denmark, 2016) and the EUROPYRO France Innovation Prize (2023), with industrial-scale plants installed at ArianeGroup facilities in France for energetic waste and PFAS destruction since 2018.
