摘要： A reverse osmosis system and method includes a pump pressurizing a feed stream, a first and second membrane array that generates permeate and brine streams. A first energy recovery device uses first energy from the second brine stream to pressurize the first brine stream. A first and second auxiliary and bypass valves are associated with the first and second energy recovery device. A second energy recovery device uses second energy from the second brine stream to increase a second pressure of the feed stream. A first flowmeter generates a first flow signal for the first permeate stream. A second flowmeter generates a second flow signal for of the second permeate stream. A third flowmeter generates a third flow signal for the second brine stream. A motor drives the first energy recovery device. A controller controls the in response to the flow signals.

摘要： A multi-stage polymeric membrane module system separates a gas, such as air, into components of high purity. In at least two of the stages, a portion of the retentate gas is directed into the low-pressure side of the module, to act as a sweep gas. The use of the sweep gas reduces the partial pressure of permeate gas on the low-pressure side of the membrane, and therefore improves the flow of permeate through the membrane. In a preferred embodiment, there are three modules. The output streams are taken from the retentate outlet of one module, and from the permeate outlet of another module. The output streams have very high purity, relative to the number of modules required, as compared with systems of the prior art.

摘要： A membrane treatment plant having at least two stages (53), (69), (75) arranged serially is disclosed. Each stage (53), (69), (75) comprises at least four membrane units (55) arranged in parallel, with each membrane unit (55) having an inlet (57), a feed/concentrate outlet (59) and a permeate outlet (61). Each stage (53), (69), (75) has a common inlet header (51), (67), or (73) and a common outlet header (65), (71) or (77), with the common outlet header (65) (71) of an upstream stage connecting to the common inlet header (67) (73) respectively of an immediately downstream stage. Each membrane unit (55) has an inlet flow control valve (93) connecting between its inlet (57) and the common inlet header of the stage in which it is located, and an outlet flow control valve (63) connecting between its outlet (59) and the common outlet header stage in which it is located. The inlet flow control valve (57) and outlet flow control valve (63) are operable to isolate the membrane unit (55) from its common inlet header and common outlet header to allow cleaning of said membrane unit to take place without disrupting operation of the remaining membrane treatment plant. A control system for the membrane treatment plant is also disclosed.

摘要： A reverse osmosis membrane apparatus has a plurality of high pressure vessels 12a and 12b in parallel with each other with respect to introducing passage 18 of clarified seawater obtained by subjecting raw seawater to sterilization and removal of relatively large foreign substances. The high pressure vessels 12a and 12b have first-stage reverse osmosis membrane elements 14a and 14b, respectively. Concentrated seawater subjected to membrane separation in the high pressure vessels 12a and 12b flows into a high pressure vessel 16. In the high pressure vessel 16, a plurality of reverse osmosis membrane elements 42 are arranged in series. When a detected value obtained by a differential pressure meter 56a or 56b provided for the high pressure vessel 12a or 12b exceeds a threshold value, introduction of the clarified seawater is stopped, and the reverse osmosis membrane element is washed or replaced.

摘要： The present invention provides counter flow cascade separation systems useful to separate solute/solute pairs present in a solvent. The separation systems include a series of interconnected stages with each stage comprising a diafilter preferentially permeable for one solute. Solute/solute pairs are preferentially separated by the diafilter into permeate and retentate flows. Stages are combined to form separation systems capable of operation approaching an ideal cascade.

摘要： A method for conditioning natural gas into fuel gas, where the method includes the step of: delivering a natural gas stream including both CO2 and C2+ hydrocarbons to a membrane separation assembly; and separating the natural gas stream into the following streams: (i) a first permeate stream, (ii) a second permeate stream, and (iii) a residual stream. The first permeate stream includes CO2 removed from the natural gas stream. The second permeate stream includes methane at a greater concentration than a concentration of methane in the natural gas stream. The residual stream contains C2+ hydrocarbons at a greater concentration than a concentration of C2+ hydrocarbons in the natural gas stream.

摘要： The invention relates to a method of operating a pasteurization plant whereby containers filled with food products and closed are treated with a tempered aqueous process liquid in one or more treatment zone(s). At least a part of the process liquid is circulated around the treatment zone(s) for reuse in at least one recirculation loop. A partial quantity of the process liquid circulated in the at least one recirculation loop is removed and fed to a cleaning device comprising a membrane filtration device. A flow rate through the membrane filtration device is continuously monitored by means of a sensor device. A volumetric flow through the membrane filtration device is influenced by adjusting a flow regulating position of at least one adjustable flow regulating means. The at least one partial flow is then returned to a recirculation loop or a treatment zone again.
