CAPACITIVE-DEIONIZATION-TYPE NUTRITIVE SALT REMOVAL SYSTEM AND METHOD FOR USE IN DAM OR WEIR

摘要

A capacitive-deionization-type nutritive salt removal system (100, 300, 1100) 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 (110) configured to take in the water; a first nutritive salt filtration unit (120, 320, 1120) configured to use capacitive deionization to primarily filter out nutritive salts from the taken-in water; a second nutritive salt filtration unit (130, 330, 1130) configured to use capacitive deionization to secondarily filter out nutritive salts from the primarily filtered water; and a nutritive salt storage tank (140) 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.
