Latest Patents
One of Wei-chi Ying's latest patents is related to the treatment of electroless nickel plating baths. This innovative process describes a method for removing nickel and phosphorus species from spent electroless nickel plating solutions. The process involves an initial precipitation of phosphite values, followed by the oxidation of hypophosphite and remaining phosphite to phosphate values. The final removal of phosphate and nickel is achieved through lime precipitation. The treated solution is separated from the precipitants, ensuring it contains less than 1 milligram per liter of nickel and/or total phosphorus species. This method is not only cost-effective but also readily adaptable for on-site use.
Another significant patent by Ying is an integrated biological-adsorption process for treating wastewater. This invention addresses the treatment of chemical process wastewaters and landfill leachates containing hazardous halogenated organic chemicals. By employing a combination of physical, chemical, and biological processes, the invention aims to produce a liquid discharge that is environmentally acceptable in an efficient and economical manner.
