Title: Innovations by Inventor Yongjun Chen Introduction Yongjun Chen is an innovative inventor based in the United States. He has made significant contributions to the field of water purification through his inventive solutions. Although he currently holds no patents, his work demonstrates a commitment to improving water safety and quality. Latest Patents Yongjun Chen's latest patents include two notable inventions. The first is a "Granular Filtration Media Mixture and Uses in Water Purification." This invention provides a granular filtration media that comprises a mixture of granular filtration media and less than 5% of nanofibers based on the dry weight. It is designed to remove contaminants from water, including metals, heavy metals, and organic matters, thereby improving the chemical safety and purity of water. One embodiment of this invention specifically addresses the removal of particulate lead from high pH water. The second patent is titled "Dual Polymer System for Water Recovery and Separation of Suspended Solids from Aqueous Media." This method involves the use of anionic and cationic polymers added in any order or simultaneously to aqueous media for the removal of substances. The sequential addition of the two biopolymers, anionic xanthan followed by cationic chitosan, leads to the rapid formation of large and cohesive fibrillar aggregates. These aggregates can be easily separated from the aqueous media by settling under gravity or through filtration.
