PURPOSE:To increase the filter efficiency by connecting a filter incorporated with both an adsorption rodlike material and a filter cylinder consisting of a magnetic material surrounding it with a flow line of a raw liquid and magnetizing the adsorption rodlike material and the filter cylinder via a magnetizing means. CONSTITUTION:A waste liquid contg. a magnetic grain such as iron content is passed through a flow line A of a raw liquid and sent into a filter B. The filter B is provided with the following filter main body b4 between a lower chamber b3 and an upper chamber b5 which is incorporated with both an adsorption rodlike material b1 consisting of a magnetic material and a filter cylinder b2 having the network fine small holes in the whole surfaces and consisting of the magnetic material surrounding the adsorption rodlike material. The adsorption rodlike material b1 and the filter cylinder b2 are intermittently magnetized with a magnetizing means C and the magnetic impurities are collected, degaussed and allowed to fall in the lower chamber b3 and discharged through an exhaust port 3 via a slanted plate 5. |
