Definitions
- the plate-and-frame-type electrodeionization apparatus has a flat membrane shape in which an anode, a cathode, and a concentration chamber and a desalination chamber (dilution chamber) are alternately formed between the anode and the cathode. It has a cation exchange membrane and an anion exchange membrane.
- the desalting chamber is filled with an ion exchanger such as an ion exchange resin.
- the water to be desalinated is circulated through the desalting chamber, and the ions in the water pass through the ion exchange membrane and move from the desalting chamber to the concentration chamber.
- the concentration chamber and the desalination chamber are partitioned by the ion exchange membrane between the anode and the cathode, and the water to be treated is passed through the deionization chamber.
- the concentrated ice is supplied such that the concentrated water flows into the concentrating chamber from a side near the outlet of the desalting chamber and flows out from a side near the inlet of the desalting chamber.
- An inflow means and an outflow means are provided, and a means for removing anion from the concentrated water flowing into the concentration chamber is provided.
- the raw water may be supplied to the desalination chamber after the anion removal treatment, whereby the anion concentration of the production water can be further reduced.
- the anion removal treatment a reverse osmosis treatment and a deaeration treatment are preferable, and in particular, a multistage reverse osmosis treatment and a further deaeration treatment are preferable.
- FIG. 1 is a schematic sectional view of an electric deflection device according to an embodiment.
- FIG. 1 is a schematic cross-sectional view of an electrodeionization apparatus 10 showing one example of the first and second aspects.
- a plurality of anion exchange membranes (A membranes) 13 and cation exchange membranes (C membranes) 14 are alternately arranged between electrodes (anode 11 and cathode 12).
- a membranes anion exchange membranes
- C membranes cation exchange membranes
- 5 and a desalting chamber 16 are alternately formed.
- an anion exchanger and a cation exchanger composed of an ion exchange resin, an ion exchange fiber or a graft exchanger are mixed or mixed. Packed in layers.
- FIGS. 7A and 7B the upper side in FIG. 7A is the inlet side, and the lower side is the outlet side in FIG. 7A, and water flows from the top to the bottom in the desalination chamber 16.
- the concentration chamber 15 the direction crossing the water flow direction in the desalting chamber 16 (the orthogonal direction in FIG. 7 a (the orthogonal direction is not necessarily strict, (Including a range of about 100 °) is provided. Is divided into two upper and lower stages in the figure, and water is passed through each of the concentrated water distribution sections 15a and 15b from the near side to the back side of the figure.
- the concentrated wastewater from the concentration chamber 15 A of the first electrodeionization apparatus 1 has a high boron concentration of 30 ppb, and part of the wastewater is returned to the inlet side of the concentration chamber 15 A, and the remainder is concentrated. Released as wastewater.
- Raw water flows through the co-current flow system into the enrichment room 15 A of the first electrodeion device 1 to become primary enriched water having a boron concentration of 30 ppb, and is discharged.
- the electrodeionization apparatus 8 there are a concentration chamber 8A on the anion membrane 8a side of the desalting chamber 8D and a concentration chamber 8B on the cation membrane 8c side, and only the anion component concentrated in the concentration chamber 8A is discharged.
- the concentration chamber 8B in which the cations are concentrated is supplied to the concentration chamber 15 of the electrodeionization apparatus 10 together with the demineralized water from the desalination chamber 8D.
- the electrodeionization device 8 thus removes and reduces only the ayon component.
