Title: Kosaku Otsubo: Innovator in Waste Water Treatment
Introduction
Kosaku Otsubo is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of waste water treatment, particularly in methods that address sulfur compounds. His innovative approach has led to the development of a patented method that enhances the efficiency of waste water management.
Latest Patents
Otsubo holds a patent for a method of treatment of waste water containing sulfur compounds. This method involves introducing waste water from a wet type desulfurization apparatus, which contains thionic acid ions, into ion-exchange towers filled with weak-basic anion-exchange resin. The resin facilitates anion exchange, and the thionic acid ions are desorbed by contacting the resin with an alkaline solution. The desorbed thionic acid ions are then decomposed by heating in the presence of acid, resulting in a decomposed solution that is neutralized before being released from the system. This innovative process is crucial for improving waste water treatment efficiency.
