WATER TREATMENT DEVICE
Document Type and Number:
Japanese Patent JP2020044457
Kind Code:
A
Abstract:
To provide a water treatment device that can suppress a transfer of a water-soluble organic matter to concentrated water that is a target of an evaporative concentration treatment.SOLUTION: A water treatment device includes: a remover, a first reverse osmosis membrane unit, a second reverse osmosis membrane unit, and a heat treatment device. The remover is filled with a renewable adsorbent, and adsorbs and removes organic substances in passing water to be treated by an adsorbent. The first reverse osmosis membrane unit separates the water to be treated that has passed through the remover into a first concentrated water and a first permeated water by a reverse osmosis membrane. The second reverse osmosis membrane unit separates the first concentrated water separated by the first reverse osmosis membrane unit into a second concentrated water and a second permeated water by a reverse osmosis membrane. The heat treatment device evaporates the water contained in the second concentrated water by applying heat treatment to the second concentrated water separated by the second reverse osmosis membrane unit.SELECTED DRAWING: Figure 1
