A system that uses magnetic force can be effective for treating sewage water because it can rapidly separate solids from liquid. We are developing such a system that uses a superconducting magnet that consumes little power but produces a strong magnetic field. The system also uses rotating magnetic filters and can be operated continuously. We constructed a prototype and tested it using sewage water. The system successfully removed 90% of BOD (biochemical oxygen demand; the BOD in the effluent for this system was less than 0.22 μm) and 97% of SS (suspended solids). This means that the total space required for a sewage treatment facility might be reduced when such a system is used.
