He has made significant contributions to the field of wastewater treatment, holding 2 patents that focus on innovative methods for treating waste liquids. His work is essential in addressing environmental challenges related to water pollution.
Latest Patents
Haraguchi's latest patents include a comprehensive method of treating wastewater. This method involves several key steps: an aluminum dissolution step that dissolves aluminum in an acidic waste liquid, followed by separation into a first treated water and a reduced heavy metal precipitate. The process continues with a gypsum recovery step, where a calcium compound is added to the first treated water at a pH of 4 or less, leading to the separation of a second treated water and gypsum. Additionally, an aluminum and fluorine removal step is included, where an alkali is added to the second treated water, resulting in a third treated water and a precipitate containing aluminum and fluorine. Finally, a neutralization step is performed, adding an alkali to the third treated water to separate it into an alkali neutralization treated water and a neutralized precipitate of heavy metal hydroxide.
Another patent by Haraguchi outlines a similar method of treating wastewater, which includes an aluminum dissolution step, gypsum recovery, and a heavy metal coprecipitation step. This method also emphasizes the importance of removing aluminum and fluorine, followed by a neutralization step to ensure the treated water meets environmental standards.
