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： An example water purification system includes a forward osmosis module, a reverse osmosis module, a pump powered by an electric motor, and a pressure sensor. The forward osmosis module may receive a feed stream and a draw stream, and may produce an intermediate product stream. The intermediate product stream may be pressurized by a pump and provided to the reverse osmosis module. The reverse osmosis module may generate a product stream and return the draw stream to the forward osmosis module. The pressure sensor may monitor the pressure of the intermediate product stream, and the pressure may be used to determine the speed of the electric motor.

摘要： A filtration system suitable for recovering base stock from used lubricating oil and other applications pass feedstock over nano-filtration membranes assembled as a stack of membranes all experiencing parallel flow. On exiting a first stack of membranes the feedstock passes through an opening in a pressure-sustaining separator plate to flow in the reverse direction past a second stack of membranes and subsequently establish a serpentine flow of feedstock through multiple stacks of membranes. The stacks of membranes all share a common pressure containment vessel. Pressure boosters installed in the flow-through openings of separator plates separating consecutive stacks can serve to restore lost pressure of the feedstock and maintain effective permeation of permeate through the membranes. A pressure control valve at the outlet to the permeate-receiving cavities of a stack can be used to adjust the trans-membrane pressure.

摘要： A dialyzer (15) includes a hollow fiber dialysis column (20), a liquid tubing section (12a), and a flow rate changing section (16a). The hollow fiber dialysis column (20) includes a hollow fiber membrane, a first flow channel that allows a dialysis target to flow internally of the hollow fiber membrane, and a second flow channel that allows an external liquid to flow externally of the hollow fiber membrane. The liquid tubing section (12a) tubes the dialysis target to an inlet (20a) of the first flow channel. The flow rate changing section (16a) is capable of changing a flow rate of the dialysis target at the dialysis target flowing out of an outlet (20b) of the first flow channel.
