摘要
To provide a fresh water treatment apparatus capable of suppressing reverse osmosis membrane blockage and stably operating while keeping a high recovery rate.SOLUTION: A fresh water treatment apparatus has: a reverse osmosis membrane; a fresh water supply pipe for supplying fresh water to the reverse osmosis membrane; a permeate pipe for transferring the permeated water of the reverse osmosis membrane; a circulating water pipe for circulating at least a part of the concentrated water of the reverse osmosis membrane to the fresh water supply pipe; and a drain pipe for draining at least part of the concentrated water of the reverse osmosis membrane. The circulating water pipe has a circulating water pressure regulating valve capable of adjusting the amount of concentrated water to be circulated, and the drain pipe has a drain pressure regulating valve capable of adjusting the amount of concentrated water to be drained.SELECTED DRAWING: Figure 1
