Document Type and Number:
WIPO Patent Application WO/2013/018236
Kind Code:
A1
Abstract:
[Problem] To provide a device and method for manufacturing drinking water that can manufacture drinking water stably with a high yield while extending the life of a reverse osmosis membrane.
[Solution] This device is provided with: a pump that pressurizes tap water; a reverse osmosis membrane that separates the pressurized tap water into waste water containing impurities and permeate water; and a tank for retaining the permeate water. The waste water is eliminated by passing through a first flow path and a second flow path which are arranged in parallel. This device is further provided with a flow rate adjusting unit, and the flow rate adjusting unit has a flow rate adjusting valve that is provided on the first flow path and controls the flow rate of waste water flowing in that flow path, a flow path opening valve that is provided on the second flow path and opens and closes that flow path, and a control unit that controls the opening and closing of the flow path opening valve.
