BWB has a department of R&D with an annual budget of 2.5 Mio € on research. BWB is currently involved as partner or coordinator in 35 projects funded by national and international programmes.
Research activity is structured along the water cycle; including water and wastewater treatment, network modelling, hydraulic engineering and new technologies. Results from R&D are presented in the national Committee for Certification and on international conferences.
Main tasks in the project:
- WP 1: One of the demonstration sites (No. 1) will be operated at BWB wells (water protection area) where bankfiltration in combination with anoxic capillary nanofiltration at single wells will be assessed for their advantages and limitations. BWB will operate and regularly monitor the demonstration site, coordinates and communicates with authorities and end users.
- WP 3: Demonstration site No. 12 will be constructed and operated at BWB WWTP Schonerlinde to demonstrate long-term viability of constructed wetlands with ozonation as pre-treatment. BWB will operate the demonstration scheme and coordinates with regular treatment scheme at the WWTP and communicates with authorities (e.g. regarding discharge permits) and end-users.
- WP 4: BWB will conduct chemical and microbiological analyses of trace organic chemicals, pathogens as well as antibiotic resistance genes at WWTP Schonerlinde.
- WP7: organisation of dissemination events
