Title: Surapol Padungthon: Innovator in Water Treatment Technologies
Introduction
Surapol Padungthon is a notable inventor based in Bethlehem, PA (US). He has made significant contributions to the field of water treatment, particularly through his innovative methods for addressing water hardness and contaminant removal.
Latest Patents
Padungthon holds 2 patents that showcase his expertise in ion exchange technologies. His first patent, titled "Ion exchange methods for treating water hardness," introduces a novel salt-free water softening method. This method utilizes an exchange medium, such as a gel exchange polymer or an inorganic cation exchanger, pre-loaded with a polyvalent cation that has low solubility in nearly neutral pH conditions. Notably, this method does not require sodium salt or mineral acid for the regeneration of the exchange medium.
His second patent, "Hybrid anion exchanger impregnated with hydrated zirconium oxide for selective removal of contaminating ligand and methods of manufacture and use thereof," focuses on the use of polymeric anion exchangers as host materials. In this invention, sub-micron sized hydrated zirconium oxide particles are irreversibly dispersed within the ion exchange medium. This innovative approach allows for the effective transport of anionic ligands, such as arsenate and fluoride, without being subjected to the Donnan exclusion effect. Consequently, the anion exchanger-supported zirconium oxide particles demonstrate a significantly greater capacity for removing these contaminants compared to traditional cation exchange resins.
