Latest Patents

One of Woo Gi Lee's latest patents is a method for manufacturing organic acid by high-efficiency continuous fermentation. This invention outlines a process that involves the continuous culture of organic acid bacteria and the collection of organic acid produced from the culture. The method employs a cell-recycle multiple-stage continuous fermentor, which includes various components such as a ferment container, temperature controller, stirrer, and pH controller. This innovative approach allows for the production of high-concentration lactic acid at a rate of 90 g/L with a productivity of 50 g/L/h. This method not only reduces facility and production costs but can also be applied to the production of other organic acids like acetic acid and citric acid.

Another significant patent by Woo Gi Lee is a method for removing nitrogen and phosphorous in wastewater. This invention utilizes fermentation broth obtained from the anaerobic fermentation of organic solid wastes. The process involves subjecting organic waste material to anaerobic fermentation and then adding the resulting broth to a sequencing batch reactor. This method achieves over 95% removal of nitrogen and maintains phosphorous levels below 1 ppm, all while eliminating the need for extra pretreatment steps or chemicals. This innovation lowers the overall cost of wastewater treatment by utilizing organic waste materials.
