Method for producing fresh water |
| abstract |
Provided is a method for producing fresh water, having a plurality of desalination processes in parallel where raw water or pre-treated raw water is treated by a first semi-permeable membrane unit, and the resulting permeate of which a pH is raised is treated in the second semi-permeable membrane unit, comprising: temporally, in part of desalination process A; lowering a pH of raw water or pre-treated water to be supplied to a first semi-permeable membrane unit A 1 and to make a pH of the resulting permeate of the first semi-permeable membrane unit A 1 lower than that of feed water of a second semi-permeable membrane unit B 2 in desalination process B to be supplied to a second semi-permeable membrane unit A 2; and mixing the permeate obtained from the second semi-permeable membrane unit A 2 with the permeate obtained from the second semi-permeable membrane unit B 2 in said desalination process B. |
