Recent Projects

Detailed overview of the last 3 projects from the area of research and development, in which we were significantly involved.


Patent granted for the process for the purification of wastewater: Biological wastewater treatment in a novel reactor with a packed bed made of an easily fluidisable plastic growth support material. The carrier material offers a specific surface area of 400 up to 600 m²/m³ and is thus up to a factor of 3 higher than the classic trickling filter materials previously used for nitrification. This makes it possible to achieve at least a factor of 2 higher space decomposition performance compared to the classic trickling filter.

Patent Certificate


Participation in the Nitro SX project: Development and successful operation of a semi-industrial test plant for the microbiological desulphurisation of biogas.


Participation in the WaterReTUNe project: development of innovative technologies for the post-treatment and recycling of biologically treated sewage plant effluent in Tunisia and other countries in the Maghreb region.

Project WaterReTUNe

Flyer WaterReTUNe


Launch of a treatment plant as part of the DEG-PPP project "Implementation of a sanitarian septic tank system in the suburban and rural area of Cambodia".

2016 - 2019

Joint project "Awaregio" - Modular wastewater treatment processes for the reuse of water, nutrients and energy.



Retrofitting of the treatment plant Hornow (1200 PT) finished. Implementation of MBBR technology into an existing plant built 1994.


Research topic is in the final stages. The project "energy-efficient clarification concept", developed by EvU® in cooperation with FIW at the RWTH Aachen and supported by AIF Berlin passed successfully its field test on the treatment plant of Hubbelrath.
