Abstract

PURPOSE:To strip away the magnetic suspensions captured by filter media and to prevent the deterioration of an electromagnetic filter by backwashing the filter media by using the cooling water which is the filtered water of high temps. circulated between the filter and a heat exchanger and is heated by cooling the filter and filter media. CONSTITUTION:In the stage of cleaning the magnetic filter media 7 of an electromagnetic filter 1 wherein the magnetic suspensions in high temp. raw water are captured, first the filter 1 is disconnected from the water flow system of the high temp. raw water. The filtered water of a high temp. in the filter 1 is circulated to a heat exchanger 3 through a circulation piping 11 forming a closed circulation system. At this time instant, cooling water is flowed to the heat exchanger 3 to cool the filtered water of high temps. gradually, thereby cooling the filter 1 gradually. On the other hand, the cooling water heated by this is stored as washing water in a washing water tank 5. Conduction of electricity to an electromagnetic coil 2 is stopped, to de-energize the media 7 and the hot washing water in the tank 5 is forced by upward current into the filter 1 from the bottom. The turbid matter captured by backwashing the media 7 is stripped by this and the waste water of the washing is discharged to the outside of the system through a pipe 16.
