PURPOSE:To provide a circulating purification system capable of being used effectively in a bathtub or swimming pool. CONSTITUTION:A circulating purification system for use in the purification of a bathtub or swimming pool is provided, in its circulating passage, with an org. material filter 3 and a high gradient magnetic separating device 2 located before such a filter. Since iron rust is first filtered from the scale-like dirt consisting of iron dust and org. components (P, S, etc.) in a colloidal form by the high gradient magnetic separating device 2 and since the org. components are then removed therefrom by the org. material filter, this system eliminates the possibility of the org. material filter being clogged with the dirt and makes it difficult for a hot water supply device to be scaled. By the circulating purification system, a rusty water counter measure is applied to a bathtub, while filtering effectively the org. compoments such as metallic soap and scale as originally intended, a hot water in the bathtub can be kept clean and the hot water is not required to be replaced each time the bathtub is used in order to save water. |
