Since phytoplankton are principal components of lake pollution, we are developing a purification system using a SMS (superconducting magnetic separator) for removing phytoplankton rapidly and energy efficiently. This system includes a new separator called as CSMS (continuous SMS). It has a twin-type superconducting magnet, a reciprocating main filter and a rotating sub-filter. The room-temperature-bore diameter of an experimental separator with this structure is 310 mm. The central magnetic field in the main filter is 1.0 T and that in the sub-filter is 0.6 T. And the lowest temperature of the superconducting magnet is 4.1K. This temperature does not depend on supply current. This system achieved a removal ratio of more than 93% of chlorophyll-a at a treatment speed of 400m^3/day. This result shows that CSMS is very useful for separating systems.
