Title: Shiro Shimura: Innovator in Waste Water Treatment
Introduction
Shiro Shimura is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of environmental engineering, particularly in the treatment of waste water from catalytic cracking units. His innovative approach addresses critical challenges in waste management and environmental protection.
Latest Patents
Shimura holds a patent for a method for treating waste water from a catalytic petroleum cracking unit. This method includes several steps: a receiving step, aeration step, settling step, and a discharging step. In the receiving step, waste water from which hydrogen sulfide and ammonium have been stripped out is introduced into a biological treatment tank. The aeration step involves subjecting the waste water in the tank to aeration for a predetermined period of time. During the settling step, activated sludge within the biological treatment tank is settled for a predetermined period. Finally, in the discharging step, the supernatant is discharged from the tank after the settling step. The total duration of the aeration step performed daily is set to no longer than 12 hours, and the aeration step is performed intermittently. This innovative method allows for the treatment of undiluted waste water, which has been challenging with conventional processes, while also reducing the amount of excess sludge generated.
