Title: Hozumi Otozai: Innovator in Water Treatment Technologies
Introduction
Hozumi Otozai is a notable inventor based in Kobe, Japan, recognized for his contributions to wastewater and water treatment technologies. With a total of 2 patents, Otozai has developed innovative solutions aimed at improving water purification processes.
Latest Patents
Otozai's latest patents include a wastewater treatment device designed to reduce fluoride ion concentration in industrial wastewater. This device enhances the recovery rate of purified water by incorporating a biological treatment unit that decomposes organic matter using microorganisms. Additionally, it features a desalinization unit that eliminates salt-forming ionic components downstream of the biological treatment unit. A pretreatment unit is also included to remove heavy metals and oil, which can inhibit the function of the biological treatment and desalinization units. Furthermore, this pretreatment unit contains a fluoride concentration reduction unit that effectively reduces fluoride ions in the wastewater.
Another significant invention is a water treatment device that minimizes electrode degradation in a capacitive de-ionization treatment section. This device maintains high water treatment capability by utilizing an activated carbon treatment section that adsorbs and removes organic matter from water with a total organic carbon concentration of 100 mg/l or less. The capacitive de-ionization treatment section employs electrodes with opposite voltages to adsorb ions from the water and subsequently release them.
