摘要： Perforated graphene and other perforated two-dimensional materials can be used in hemodialysis membranes and blood filtration membranes for selective removal of components from blood in vivo and ex vivo. The membranes are useful in hemodialysis and hemofiltration techniques to provide improved patient care. Hemodialysis systems can include a hemodialysis membrane formed from perforated graphene or another perforated two-dimensional material disposed upon a porous support structure. Hemofiltration systems can include one or more and preferably two or more blood filtration membrane formed from perforated graphene or another perforated two-dimensional material disposed upon a porous support structure. Methods for performing hemodialysis can involve exposing blood from a patient to a hemodialysis membrane formed from a perforated two-dimensional material. Ex vivo dialysis techniques can be performed similarly. Methods for filtration of blood can involve passing blood through one or more filter membranes or through a plurality of sequential filter membranes.

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 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.

One or more of the filtration elements is a reverse osmosis membrane or a nanofiltration membrane and one of the other filtration elements is a microfiltration or ultrafiltration membrane. The vessel has an inlet port for providing a liquid feed to the filtration elements, an outlet port for directing a permeate produced by the elements from the vessel and an outlet port for directing a concentrate produced by the elements from the vessel. A number of vessels can be provided in a parallel arrangement and/or a series arrangement and the vessels can be arranged so as to allow regeneration of the microfiltration or ultrationfiltration membranes from another vessel in the arrangement.

摘要： A compact fluid purification device includes a housing having an inlet for receiving unfiltered liquid and an open end and a first valve disposed within the inlet and being configured to only permit unfiltered liquid to flow into a hollow interior of the housing. The device has a plunger that is movable between a fully extended position and a fully retracted position. Movement of the plunger toward the fully extended position causes unfiltered liquid to be drawn into the interior of the housing and the device includes a second valve disposed within the outlet and being configured to only permit filtered liquid to be discharged from the plunger housing. The unfiltered liquid is filtered when the plunger is moved toward the fully retracted position causing the unfiltered liquid in the interior to flow into the inside of the filter elements and then across the filter elements and into the outlet.
