METHOD AND DEVICE FOR WATER PURIFICATION

PROBLEM TO BE SOLVED: To enhance taste of water by providing an ultrasonic wave generation part or an electromagnetic wave generation part for making clusters of water fine on a portion of a water path between a washing filter basin and a water purifying basin. SOLUTION: Raw water fed from a water source is fed to an arrival water well 1, and chlorine 2, is added then the treating water is charged with a flocculant 3, and is fed to an aggregation and precipitation basin 4, and here a kneading treatment and a flock treatment are performed to separate a precipitation component 5. The separated treating water is fed to the washing filter 6, is filtered and the treating water is fed from a ceramic-made lower part water collection device 7 to the water purifying basin 15 through a water path 13. At that time, the electromagnetic wave generation 10 and the ultrasonic wave generation part 11 are provided in the water path part 13, and the clusters in the water are made fine with works of these respective generation parts 10 and 11. Thus, a mineral component concentration in the water is made high and the water becomes tasty.
