ESA demonstration container
In a project supported by the European Space Agency, HYDROHM has constructed a demonstration container in collaboration with Semilla Maritime Solutions (FR, local coordination) and FGWRS (FR, greywater treatment). The container houses two showers and a sink of which the wastewater will be treated by the FGWRS system for toilet flushing. The URIDIS system by…

EVENTWC-LAUFEN toilet truck
We have installed a demonstration version of our urine treatment system in the high-end toilet truck by EventWC (DE) and Laufen (CH). The truck was premiered at the ISH 2023 international trade fair in Frankfurt and will be deployed at events across Germany, Austria and Switzerland.

URIDIS demo
HYDROHM has constructed two mobile demonstration units that consist of a public toilet container coupled to a technology container that houses the toilet wastewater treatment technology. The first version has been operational since the summer of 2021, while the second version has been operational since the spring of 2022. Both containers are equipped with educational…

Disinfection of reuse water for the wine sector
Increasing periods of drought urge farmers towards local reuse of water. Viticulture is a particular example where the processing of the grapes for wine production happens on or close to the farm and is water intensive. The reuse of that water for irrigation after collection and treatment can offer a solution towards the drought. However,…

LUCRA – electrochemical biosuccinic acid extraction
LUCRA is a Circular Bio-based Europe Joint Undertaking (CBE JU) funded initiative on a mission to revolutionise biobased chemicals. Ten industrial partners and renowned research centres representing the whole value chain from feedstock to products have joined forces to demonstrate the technical and economic feasibility of transforming organic waste into bio-succinic acid on a pre-industrial…

E-HYDRO – electrochemical extraction of organic acids from fermentation
HYDROHM and Pureblue Water teamed up in a CrossRoads2 Sustainable Energy project. Together, we developed and tested an electrochemical hydrolysis technology that enables cost-effective and energy-neutral decentralised water treatment. Furthermore, our technology creates the opportunity to upcycle the organic stream through fermentation, which can result in the production of valuable products such as bioplastics.

Ammonia recovery and regeneration of scrubbing acid
Ammonia removal is increasingly replaced by recovery. Recovery allows reuse and value creation in a local circular economy and does not result in release of N2O as a potent greenhouse gas. In the state of the art, ammonia is released from the waste (stripping) and captured in liquid (scrubbing). The liquid is a strong acid…
