Abstract: An object of the present invention is to, in a pure water production apparatus that utilizes a mixture of a plurality of kinds of feed water and uses a semi-permeable membrane, effectively utilize energy of concentrate discharged from a• semi-permeable membrane unit and provide, at low cost, apure water production apparatus and method that effectively use an isobaric type energy recovery unit that can efficiently recover energy against feed water variation. For the object, in a pure water producing method by supplying and having a plurality of kinds of feed'water with different water qualities permeated through a semi-permeable membrane to produce the pure water, a portion (referred to as first feed water) of the plurality of kinds of feed water supplied to a semi-permeable membrane unit comprising the semi-permeable membrane is boosted by utilizing an isobaric type energy recovery unit that recovers pressure energy of concentrate discharged from the semi-permeable membrane unit, the rest (referred to as second feed water) of the plurality of kinds of feed water is boosted by a high pressure pump, and the boosted first and second feed water are supplied together to the semi-permeable membraneunit.
