Title: Hajime Ikuta: Innovator in Wastewater Treatment Technologies
Introduction
Hajime Ikuta, an accomplished inventor based in Tokyo, Japan, holds an impressive portfolio of six patents focused on advancements in wastewater treatment solutions. His innovative methodologies aim to address critical environmental challenges related to nitrogen pollution in wastewater.
Latest Patents
Among his latest patents, Ikuta has developed a groundbreaking method for treating ammoniacal nitrogen in wastewater. This method utilizes biologically oxidizing techniques to convert ammoniacal nitrogen into nitrite and nitrate nitrogen at controlled rates. A significant aspect of this process involves an inactivating treatment step, which sterilizes or inhibits the bacteria in the sludge, followed by a nitrifying treatment that effectively oxidizes the ammoniacal nitrogen. By adjusting the biomass of the bacterial sludges and the timing of inactivation processes, the production of nitrite and nitrate nitrogen can be efficiently managed.
Additionally, Ikuta has patented a wastewater treatment apparatus that enhances the accumulation of ammonium oxidizing bacteria. This innovation involves subjecting activated sludge to an alkali treatment that raises the pH to 10 or higher, ensuring a higher priority accumulation of beneficial bacteria.
