TY - JOUR N2 - In the present investigation we studied the effects of static magnetic field on transformation of organic compounds and ammonium nitrogen. The research was carried out on laboratory scale at room temperature. Two continuously operating test systems were run in parallel. In one of the systems the raw sewage was exposed to magnetic field strength of 180 mT. The magnets were attached to a pipe used for raw sewage. The second system was used as a control. The research was carried out without activated sludge and with activated sludge. The investigation carried out in an experiment without activated sludge showed that the removal of COD for system with the raw sewage exposed to magnetic field strength of 180 mT was 15% higher then system in absence of magnetic field. During investigation carried out in an experiment with activated sludge it was observed that the removal of COD was similar in both systems. The nitrification rate for system in which raw sewage was exposed to magnetic field was lower than the system in which it was not.
