摘要： The present invention provides a cleaning agent, a cleaning liquid, and a cleaning method, which are capable of effectively removing a contaminant that is not able to be sufficiently removed by conventional cleaning liquids in cases where aromatic polyamide reverse osmosis membranes used in water treatments are contaminated and the performances of the aromatic polyamide reverse osmosis membranes such as the permeation flux and the desalination rate are deteriorated. The present invention provides a cleaning agent for aromatic polyamide reverse osmosis membranes, the cleaning agent being composed of an aqueous solution which has a pH of 13 or more and contains a stabilized halogen, a chelating agent that contains one or more substances selected from among aliphatic carboxylic acids containing no amino group, phosphonic acid compounds containing no amino group, polyphosphoric acids, and salts thereof, and an alkaline agent. According to the present invention, an aromatic polyamide reverse osmosis membrane is cleaned with use of a cleaning liquid that is composed of an aqueous solution of this cleaning agent. A chloramine compound which is obtained by mixing a compound having a primary amino group with hypochlorous acid and/or a hypochlorite is suitable for use as the stabilized halogen.

摘要： The method for purifying liquids purifies a saline liquid, e.g., salt water, using a plurality of first phase reverse osmosis (RO) units and at least one final phase reverse osmosis unit. The plurality of first phase reverse osmosis units are arranged in series. At least some of the concentrate in a last reverse osmosis unit of the series is recycled back to the permeate or output side of that unit to provide a mixed permeate. The mixed permeate is then passed successively to the permeate side of each preceding reverse osmosis unit in the series. This increases the salt content of the liquid in the permeate side of each phase, thus reducing the concentration differential across reverse osmosis membranes of the first phase reverse osmosis units.

摘要： A desalination apparatus includes a pretreatment device (13) having a pretreatment membrane (13a) that filters suspended matters in raw water (11) with added chlorine-containing water (12), a reverse osmosis membrane device (17) having a reverse osmosis membrane (16) that removes a salt content from filtrate water (14) supplied from the pretreatment device (13) to produce permeated water (15), and a reducing-agent injection device (30) that neutralizes the added chlorine on an upstream side of the reverse osmosis membrane device (17). The reducing-agent injection device (30) extracts a part (14a) of the filtrate water (14), adds metering SBS solution (18) to the part, obtains a maximum change point (equivalence point) of the oxidation-reduction potential of a reducing agent and chlorine, obtains reducing-agent additive concentration (Csm) corresponding to the equivalence point, and supplies the SBS solution (18) corresponding to the concentration to the filtrate water (14) to thereby neutralize the chlorine.
