Deutsches Institut für Bautechnik – German Institute for Civil Engineering
The BusseMF domestic waste water treatment system received the of Deutsche Institute für Bautechnik DIBt certification Berlin in 2001 it was the first small scale system with MBR technology that was certified in Germany.
Ten years after the development and market launch of the BusseMF the system was again certified by the testing institute PIA of RWTH Aachen. The new European water framework directive required certification of the system according to EN norm 18333 necessary, because of the higher requirements for relevant reduction standards (reduction of carbonate, nitrate and phosphorous). The BusseMF surpassed all test parameters and can therefore be used even in very sensitive water protection areas, such as drinking water protection zones and nature reserves.
The German Institute for Civil Engineering confirmed three new design approvals issued in 2010 that the BusseMF meets all the requirements for all known reduction standards. The design approval number Z-55.3-60 confirmed the reduction standards for N + H, the design approval number Z-55.3-317 confirmed the reduction standards D + H and number Z-55.3-327 the reduction standards D + N+ P. The local water authorities define which reduction standards have to be met in which region. According to that definition the BusseMF is equipped to meet the required standards for the respective regions.
