What is a Circulating filtration device?

A circulation filtration device is a device that filters hot springs, tap water, etc. and circulates filtrate. Circulation filtration equipment can be divided into two types, physical filtration equipment and biological purification equipment, depending on the function. Physical filtration devices are used to remove foreign substances that are insoluble in water, such as fine particles, hair, and fibers. Biological purification equipment uses a filter medium such as activated carbon as a support to propagate microorganisms. It has almost no physical filtration function, but microorganisms can decompose pollutants in the water.
