Based on the EvU^®-process you can efficiently and cost-effectively activate or upgrade existing clarification plants. The biological stage and secondary treatment stage are usually the weak points of a waste water treatment plant which might reach its capacity limit and can´t guarantee process stability anymore because of changing parameters of the incoming sewage and stricter regulations about effluents. We evaluate site specific data and test, also in cooperation with local engineering companies, possibilities to implement solutions with EvU^® technology and install the best option.

The biofilm process is one of the oldest technical procedures of biological wastewater clarification. It is proven that biofilms are capable of remarkable performances in wastewater cleaning. There are obvious advantages: the installation of compact plants that are Highly efficient, can be done eco-friendly and in general, without using chemical agents.

Pure Biological Wastewater Treatment
The EvU^®–process is based on an activated sludge biology combined with the moving bed biofilm biology. Activated sludge and microorganisms, in form of a biofilm, settle on mechanical and biological durable carrier material. Our developed EvU-Pearl® carrier material has a large, specific growth area (m²/m³ bulk volume) which achieves a significant increase in active bio mass concentration per m³ tank volume.

There will be only minor reconstruction work necessary to activate biofilm- and activated sludge technology within the reactor. Often you can continue to use facilities, for instance service building, preliminary and secondary/tertiary treatment facilities. Without any obligations, we evaluate the potential of your wastewater treatment plant with the EvU^®-process.
