Abstract

The present invention is a reverse osmosis treatment device equipped with a first vessel (80) for subjecting water to be treated to a primary treatment and a second vessel (82) for subjecting water to be treated which has been treated by the primary treatment to a secondary treatment wherein: the interiors of the first and second vessels (80 82) are each provided with an element (22) equipped with a reverse osmosis membrane or a plurality of said elements connected in series by a water collecting pipe; the first vessel (80) has a first discharge pipe for discharging permeated water and a permeated water flow adjustment valve (64) for adjusting the pressure inside the first vessel (80) and connected to the first discharge pipe; and an energy recovery device (150) is positioned between the first discharge pipe and the permeated water flow adjustment valve (64).
