Title: Innovations by Inventor Hung-Ta Chen
Introduction
Hung-Ta Chen is a notable inventor based in Tainan, Taiwan. He has made significant contributions to the field of wastewater treatment, holding 2 patents that focus on innovative methods for recycling sludge and treating complex wastewater.
Latest Patents
One of his latest patents is a "Method for recycling sludge during waste-water treatment." This method utilizes a process of chemical coagulation to produce sludge rich in copper ions. The sludge is then leached in a sulfuric acid storage tank with sulfuric acid of concentration 1-2N, resulting in an extractive solution with copper enrichment of 18-39 g/L and residues. The extractive solution is processed in a refrigeration crystallization tank to form copper sulfate crystals. The residues produced are added into the coagulation tank as a coagulant in the chemical coagulation process for wastewater treatment, achieving a goal of zero sludge production.
Another significant patent is the "Integrated technology in sequential treatment of organics and heavy metal ions wastewater." This invention offers an integrated technology for treating wastewater that contains low biodegradable organics and heavy metal ions, particularly from surface finishing processes. The low biodegradable organics are oxidized by a Fenton process with a pH ranging from 2 to 5 and a temperature from 20°C to 100°C. Heavy metal ions are treated by a ferrite process with a pH ranging from 8 to 12 and a temperature from 20°C to 100°C. This integrated technology is advantageous for treating wastewater, decreasing the production of iron sludge caused in the Fenton process, and improving the quality of ferrite products.
