EvU® Innovative Umwelttechnik GmbH

EvU® Innovative Umwelttechnik GmbH is an established company that continuously researches, develops and implements modern and environmentally-friendly technologies for the industrial and municipal sewage sector. Our procedures for the use of eddyable biofilm biology by means of EvU-Pearl® have grown in their own development and are constantly being further developed.
For more than 25 years, EvU® has been responsible for the development of environmental technology (Entwicklung von Umwelttechnik). Through our research, we actively take responsibility for our environment.
As a full-service provider, we support projects from the outset and as a long-term partner. The performance portfolio of EvU® ranges from the planning, design, delivery and installationright up to commissioning and maintenance, even from existing plants. With our expertise and our in-house laboratory, we are able to determine the basic parameters and process steps for the treatment of sewage water. EvU-Pearl® is a high-performance carrier material for industrial, communal and other specialized applications that require the use of biofilms for wastewater treatment. On EvU-Pearl® different biologically active organisms settle on the outside and inside. Inside, the protected area, a relatively strong, predominantly aerobic and anoxic working biofilm is formed. A weaker biofilm with predominantly aerobic microorganisms forms on the outer side. The geometry of the carrier material is stable and the wastewater easily flow through the material, allowing for a stable biofilm, which optimally utilizes the existing surface – even in a very high-suspended environment.


The carrier material enables optimal results and can be adapted to specific project requirements. Based on the long-term experience in the field of municipal and industrial wastewater treatment, EvU®-Innovative Umwelttechnik GmbH is planning and building a test facility based on the SBR method in combination with the described free-moving biofilm biology. Important aspects are the scientific exchange between German and Chinese project partners regarding the appreciation potential of the Chinese sewage treatment plants as well as the extensive publication of the project results. Through the opportunity to carry out the R & D co-operation project, EvU®-GmbH would like to expand its R & D competencies with regard to technical waste water treatment. Our goal is
to consistently address the problems of our customers and to offer individual solutions. The development of a cleaning stage for extensive wastewater treatment with extreme demands on the quality of the process enables EvU® – GmbH to extend its strategic scope to include further areas of the industrial sewage sector and strengthen the market position of our core competences.
