Title: Innovations by Nobuhiro Orita
Introduction
Nobuhiro Orita is a prominent inventor based in Tokyo, Japan, known for his significant contributions to water treatment technologies. With a total of 15 patents to his name, Orita has developed innovative solutions that address critical environmental challenges.
Latest Patents
Orita's latest patents include a water recovery apparatus and an electrodialysis device designed for treating wastewater containing scale components, organic substances, and inorganic ions. This technology is particularly useful in closed system environments such as nuclear shelters, space stations, and manned spacecraft for missions to the Moon or Mars. The apparatus efficiently recovers water by first removing hardness components through a softening device. It then utilizes a high-temperature and high-pressure electrolysis device to eliminate organic substances, urea, and ammonia. The treated water undergoes further processing through a deaeration membrane device and a two-stage acid/alkali manufacturing electrodialysis treatment.
Another notable patent involves a method for treating etching solutions used in silicon etching processes. This method selectively removes multivalent ions and a portion of alkali metal ions through a membrane separation unit that employs a nanofiltration membrane. The permeated solution is then recirculated to the etching bath, promoting sustainability in the manufacturing process.
