In order to provide a device and a method for increasing blood flow and an insulin-like growth factor with use of a large amount of carbonic gas nano bubbles, the device of the present invention includes: a bathtub; and a nano bubble-producing sectionfor producing carbonic gas nano bubbles in bath water in the bathtub

Device and method for increasing blood flow and insulin-like growth factor

Ultrapure water having a reduced amount of TOC and a low electrical conductivity is produced in correspondence with a variation in water quality of raw water. A first water tank has an anaerobic organic matter treatment chamber and an aerobic organic matter treatment chamber which are communicated with each other at their bottom portions. Activated carbon bags are arranged in upper portions of both the chambers, and Bincho charcoal is stowed in the lower portion of the chambers. With this arrangement, carbon compounds and organic nitrogen compounds in the water to be treated are biologically treated by microbes, thereby reducing the TOC. Furthermore, nitrate nitrogen generated through the organic nitrogen compound treatment process is denitrified by the anaerobic microbe, thereby reducing the electrical conductivity of the water to be treated. Both activated carbon towers perform an advanced treatment on remaining carbon compounds and remaining organic nitrogen compounds in the water to be treated from the aerobic organic matter treatment chamber. A controller controls the rate of circulation of the water to be treated and the rate of stirring of the water to be treated on the basis of a signal from a TOC meter, thereby ensuring the water quality of the water to be treated.

System for producing ultrapure water having a TOC density of no more than 0.5 ppb
