FORWARD OSMOSIS/REVERSE OSMOSIS HYBRID SEAWATER DESALINATION APPARATUS AND METHOD

摘要

Purpose: the desalination plant and its method that a FO/RO is mixed enter 1 kilowatt hour from the energy consumption that a desalting process is arranged to reduce a reverse osmosis, reduce the dirt generated from the hollow permeable membrane of a dipping multi, using bubble, sprayed below a dipping tank. Construction: the desalination plant of FO/RO mixing includes: a dipping tank (10), secondly provides the technique (2) of sewage by a sewage transfer line; The first infiltration film module (20) being installed on dipping tank for diluted high concentration seawater is provided as an induction solution by the concentration difference with sewage; One reverse osmosis membrane module (40) separates and discharges diluted seawater and enter filtrate and concentrate; One low-lift pump (30) provides diluted seawater to reverse osmosis membrane module; One dirt retarder reduces dirt, generates on the first infiltration film module. The seawater desalination method of one FO/RO mixing includes providing a sewage supply process of sewage to dipping tank, first osmosis process, the diluted concentration of its seawater for being used for the concentration difference by sewage and seawater, a hyperfiltration, separation seawater enter filtrate and concentrate.
