PROBLEM TO BE SOLVED: To obtain filtering characteristics repeatedly usable for a long period of time without occurring clogging. SOLUTION: A raw water chamber 3 and a treated water chamber 4 are provided so as to hold a magnetic lattice 2 therebetween and respectively have a water inflow port 5 and a water discharge port 6 and a magnetic powder is provided on the magnetic lattice 2 so as to form a layer while a magnet 8 is provided above the magnetic lattice 2 and the magnetic lattice has meshes larger than the magnetic powder and the magnetizing means 9 of the magnetic lattice 2 is provided in the vicinity of the magnetic lattice 2. By this constitution, a filter capable of eliminating constitution for holding the magnetic powder, having no concern for clogging, repeatedly usable over a long period of time and stable in capacity can be realized. |
