Title: Mamoru Shibuya: Innovator in Radioactive Waste Water Treatment

Introduction

Mamoru Shibuya is a notable inventor based in Aichi, Japan. He has made significant contributions to the field of environmental technology, particularly in the treatment of radioactive waste water. His innovative approach addresses critical issues related to radioactive waste management.

Latest Patents

Mamoru Shibuya holds a patent for a volume-reducing solidification treatment method for radioactive waste liquid containing boron, primarily in the form of boric acid or borates. The patent outlines a process where an alkali is added to the waste water to adjust its pH. After optional evaporation concentration, soluble calcium compounds such as Ca(OH)₂ are introduced. The waste water is then stirred at a specific temperature to form insoluble calcium borate, which is aged at a lower temperature than that of forming borate. The process includes evaporation and concentration to raise the concentration of the solid component. The resulting concentrated liquid is solidified with cement, and it may also be dried into a powder using a thin film evaporator. Additionally, the liquid containing insoluble calcium borate obtained after solid-liquid separation can be recycled for use as a waste water pH adjusting agent.
