    摘要: According to the present invention, a filtration method capable of prolonging the life of a filter and regenerating it without impairing the efficiency can be provided. Further, a filter regenerating method and a regenerating apparatus, for efficiently regenerating a filter, are provided. The filtration method of the present invention is a method of subjecting a liquid to filtration by using a resin media filter, wherein ultrasonic waves at a frequency of at least 30 kHz are applied to the filter while the filtration is carried out, during the temporary stop of the filtration or after completion of the filtration. Efficient purification is possible by subjecting a polishing composition to filtration by such a filtration method. Further, the filter regenerating method of the present invention comprises applying ultrasonic waves at a frequency of at least 30 kHz to a used resin filter.
