Title: The Innovative Contributions of Inventor Mao-Sung Lee
Introduction
Mao-Sung Lee is a noteworthy inventor based in Hsinchu, Taiwan. With a focused expertise in water purification technology, he holds a total of three patents that highlight his contributions to environmental sustainability. His inventions, aimed at addressing critical issues surrounding water contamination, showcase his commitment to innovation and improving public health.
Latest Patents
One of Mao-Sung Lee's most significant patents is a method for arsenic immobilization in crystalline form from water. This innovative technique utilizes a reactor equipped with a fluidized bed of carriers. By mixing an arsenic-containing influent with a sulfide aqueous solution or metallic salt aqueous solution at a predetermined pH, the process results in the formation of crystals of arsenic sulfides or arsenic acid metal salts. Thus, the arsenic is effectively removed from the influent, leading to an effluent with significantly reduced arsenic content. The carriers, upon which the crystals are formed, are periodically removed, allowing for continuous operation.
Another crucial patent focuses on a crystallization process for removing fluoride from wastewater. In this inventive process, fluoride-containing wastewater is introduced into a fluidized bed crystallizer with a carrier. By adding a water-soluble sodium reagent and a water-soluble aluminum reagent into the fluidized bed, crystallized cryolite (Na,AlF₆) forms on the carrier. This effectively separates the treated wastewater from the crystallizer, yielding primary treated water that has a low fluoride content. The resulting cryolite is easy to reuse, containing less than 10% water.
