Title: Innovations by Hideyo Yamauchi
Introduction
Hideyo Yamauchi is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of water treatment, particularly in methods for managing ammonium-nitrogen in water sources. With a total of 2 patents, his work has implications for environmental sustainability and water quality management.
Latest Patents
Yamauchi's latest patents focus on a method for treating water containing ammonium-nitrogen. This innovative approach involves introducing raw water into a nitrification tank, where the nitrification of nitrite-nitrogen is inhibited by ammonium-nitrogen. This process allows for stable nitrification of nitrous acid type at high loads, facilitated by ammonium oxidizing bacteria. Additionally, carbonate and/or bicarbonate are added to maintain the inorganic carbon concentration in the nitrification tank at 35 mg-C/L or more. The nitrified liquid is then transferred to a denitrification tank, where denitrifying bacteria utilize the remaining ammonium-nitrogen as an electron donor and nitrite-nitrogen as an electron acceptor.
