Patent number: 11274051Abstract: A capacitive-deionization-type nutritive salt removal system and method uses capacitive deionization (CDI) to remove nutritive salts that cause eutrophication of water due to a water-bloom phenomenon in water held by a dam or a weir. The system includes an intake pump configured to take in the water; a first nutritive salt filtration unit configured to use capacitive deionization to primarily filter out nutritive salts from the taken-in water; a second nutritive salt filtration unit configured to use capacitive deionization to secondarily filter out nutritive salts from the primarily filtered water; and a nutritive salt storage tank configured to collect and store nutritive salts filtered through the second nutritive salt filtration unit. When one filter train is operating the first or second nutritive salt filtration unit, another filter train is subjected to automatic cleaning in a standby state.Type: GrantFiled: August 10, 2018Date of Patent: March 15, 2022Assignee: Doosan Heavy Industries Construction Co., LtdInventors: Hyun Sung Choi, Seog Hyeon Ryu, Seong Ju Kim, Jang Yong You, Seok Ho Choi

Patent number: 10867755Abstract: A method for manufacturing a capacitive deionization electrode exhibits enhanced ionic material adsorption efficiency. The method includes (a) kneading an electrode active material while adding a solvent to the electrode active material; (b) adding a solvent to the mixture obtained after (a) and stirring the result; and (c) preparing an electrode slurry by adding a binder to the mixture obtained after (b) and stirring the result. According to the method, a problem of a binder blocking electrode pores, which used to occur when using existing methods, is resolved by increasing mixing efficiency of the binder while using an electrode active material having a high specific surface area. A capacitive deionization electrode having very superior ionic material adsorption efficiency may be manufactured using the method.Type: GrantFiled: August 14, 2018Date of Patent: December 15, 2020Assignee: Doosan Heavy Industries Construction Co., LtdInventors: Jang Yong You, Seok Ho Choi, Hyun Sung Choi, Han Joo Kim, Dong Ju Lee
