- Abstract
Ultrafine bubbles (UFB, Nanobubbles), which are fine bubbles with a bubble diameter of 1 μm or less, have been studied in many fields and become to be practically used. UFB suspended water can be applied for cleaning technology also. Urinary calculus, which is a kind of scale, is produced in pipe, heat exchanger and others, with decomposition of urea. It is a problem in toilets because it promotes the propagation of bacteria when it adheres, clogging water distribution pipes. In this research, the effect of UFB onto the adhesion (production) of urinary calculus is studied and its properties are investigated. It suggests that UFB existence would take the structure of urinary calculus to be brittle on the basis of urinary calculus adhesion during 3 month. Its effect would take scale adhered to be easily removal, while the inhibition of accumulation of urinary calculus could not observed by the existing of UFB.
