水処理システム及び水処理方法
Document Type and Number:
Japanese Patent JP7293079
Kind Code:
B2
Abstract:
To provide a water treatment system and a water treatment method which enable a reverse osmosis treatment of water with a high TDS concentration of 40000 mg/L or higher with sufficiently low water pressure.SOLUTION: A water treatment system includes a reverse osmosis membrane device to which treated water with a TDS concentration of 40000 mg/L or higher is supplied, permeate flow rate measuring means for measuring the flow rate of permeate water treated by the reverse osmosis membrane device, concentrated water flow rate measuring means for measuring the flow rate of concentrated water treated by the reverse osmosis membrane device, and a control unit which controls the flow rate of the concentrated water measured by the concentrated water flow rate measuring means so that the flow rate of the concentrated water measured by the concentrated water flow rate measuring means is 10 times or more than the flow rate of the permeate water measured by the permeate water flow rate measuring means.SELECTED DRAWING: Figure 1
