Title: Innovations of Li-Hsing Shih in Waste-Water Treatment
Introduction
Li-Hsing Shih is a notable inventor based in Tainan, Taiwan. He has made significant contributions to the field of waste-water treatment through his innovative methods. His work focuses on recycling sludge, which is a critical aspect of environmental sustainability.
Latest Patents
Li-Hsing Shih holds a patent for 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. Furthermore, the residues produced are added into the coagulation tank as a coagulant in the chemical coagulation process for waste-water treatment, achieving a goal of zero sludge production.
