Hydromars AB is a Swedish science-based deep-tech company that develops a circular water system for deep space missions.
Based on proprietary technology from its parent company, Hydromars uses a new unit operation that will make it possible to perform the main task of recycling in the spaceship and achieve complete recovery and 100% clean water.
Hydromars’ product comprises three basic steps: evaporation of volatiles, extraction of ultra-pure water via hydrophobic membranes, and separation of water from the resulting brine/sludge by evaporation/crystallization. This results in the complete recycling of any kind of wastewater in a simple, affordable way facilitating missions in deep space and reducing water costs for shorter missions.
The technology concept used by Hydromars has been tested for the treatment of municipal and several industrial wastewaters, desalination, and the concentration of brine in cooperation with the Royal Institute of Technology (KTH) and the IVL Swedish Environmental Research Institute. Demos have been tested in Greece, Spain, Saudi Arabia, and Qatar. After a ten-year endurance test tools have been manufactured in 2021 and the core component is under testing. The next step is to test it in zero gravity.
By solving challenges for space, Hydromars also aims to contribute to the long-term survival on Earth, especially where achieved know-how can be used to market or to spin off products where there ultimately is a need to close the loop.
Hydromars collaborates with leading Institutes (German Aerospace Centre, European Space Agency, KTH Royal Institute of Technology) and multinationals (Airbus Defence & Space) and has received initial funding and a Seal of Excellence from the EU.
