Title:
SALT WATER DESALINATION EQUIPMENT USING REVERSE OSMOSIS MEMBRANE, AND METHOD FOR PRODUCING DESALINATED WATER USING SALT WATER DESALINATION EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2010/004819
Kind Code:
A1
Abstract:
Salt water desalination equipment comprising a reverse osmosis membrane module, a high-pressure pump, a device for collecting and boosting energy, and pipelines for connecting these elements of the equipment, wherein a pipeline extending toward the high-pressure pump and supplying salt water has a branch, and a reverse osmosis membrane, obtained by injecting a medicine for bringing the hydrogen-ion exponent (pH) of the salt water to below 4 at the time of touching the reverse osmosis membrane in the reverse osmosis membrane module, is used in a salt-water-supply pipeline extending from the branch toward the device for collecting and boosting energy or in a salt-water-supply pipeline extending from the branch toward the high-pressure pump.
