Abstract:
This water purification apparatus comprises: a raw water introduction part for introducing raw water; a filtration part for filtrating solid contents included in the raw water; a flow passage for filtration that is set so that when filtering raw water, the raw water introduced from the raw water introduction part is discharged to the outside at least through the filtration part; a flow passage for backwashing that is set so that when backwashing a filtering medium in the filtration part, the raw water introduced from the raw water introduction part passes through the filtration part in the flow direction opposed to the flow of the raw water in the flow passage for filtration and is discharged to the outside; and multiple switching valves for switching the setting between the flow passage for filtration and the flow passage for backwashing. The water purification apparatus has, within the flow passage for backwashing and between the raw water introduction part and the filtration part, a bubble introduction part for introducing bubbles into raw water.
