UFB, ULTRA-FINE BUBBLE* is an extremely tiny gas bubble contained in water. Regarding bubble size, Ultra-fine bubble and micro bubble are categorized of which UFB is defined by ISO and global representatives, the bubble diameter is less than 1 μm, also known as Nano Bubble. Recently there are various types of UFB device , however different UFB production principles will result in different physical properties. UFB Technology has been developed in Japan for many years, broadly used in cleasing, deodorization, water purification, medical, agriculture and recently applied to medicine, pharmaceuticals, cosmetics, semiconductors, foods, beverages, agriculture, forestry and fisheries as a safe, efficient and economical solution. UFB Technology will potentially become a dominant industry with a large growing worldwide market.
