Title: Innovations by Inventor Xiangyi Qiao
Introduction
Xiangyi Qiao is a notable inventor based in Singapore, SG. He has made significant contributions to the field of water treatment and electrochlorination. With a total of 3 patents, his work focuses on innovative processes that enhance water purification and disinfection.
Latest Patents
One of his latest patents is titled "Process of using demineralized water for chlorate reduction in on-site brine electrochlorination systems." This electrochlorination process involves treating water from a source in an advanced water conditioning system that removes a portion of anions and cations, producing demineralized water. The demineralized water is then blended with sodium chloride to form a brine solution, which is treated in an electrolyzer to create a disinfection solution containing sodium hypochlorite with a chlorate concentration of less than 0.25 mg/L.
Another significant patent is "Selenium removal using aluminum salt at conditioning and reaction stages to activate zero-valent iron (ZVI) in pironox process." This invention discloses a system with a reactor vessel containing zero-valent iron media, a source of a conditioning additive, and a reaction additive. The method aims to reduce contaminants in water by contacting zero-valent iron media with a conditioning additive and introducing a reaction additive, both of which may contain an aluminum salt.
