A housing of a separation apparatus includes therein a zeolite membrane complex. A sheath includes therein the housing. A fluid supplied to the inside of the housing has a temperature higher than the temperature around the sheath. A second exhaust port is used to exhaust a permeated substance that has permeated through the zeolite membrane complex in the fluid to the outside of the housing. The permeated substance exhausted from the housing can be led into an exterior space between the sheath and the housing through the second exhaust port and can be exhausted through an exterior exhaust port. At least part of the zeolite membrane complex is included in an inter-port space surrounded by the sheath, the second exhaust port, and the exterior exhaust port. This structure reduces energy required for fluid separation performed under high temperatures.

A subsea fluid processing system which receives a wellstream flow. The subsea fluid processing system includes a pressure control device which regulates a pressure of the wellstream flow, a gas-liquid separator unit which receives the wellstream flow downstream of the pressure control device and which provides a liquid stream and a gas stream, a first membrane separator which receives the gas stream and which provides a retentate stream and a permeate stream, a compressor which receives the permeate stream and which provides a compressed permeate stream, and a discharge cooler which receives the compressed permeate stream and which provides a cooled compressed permeate stream for injection into a subsurface reservoir. A density of the cooled compressed permeate stream is higher than a density of the compressed permeate stream.

The present invention relates to modification to permeate channels and permeate materials in a cross-flow filtration system to improve performance in counter current filtration having both retentate channels and permeate channels wherein a solution is pumped through one of the channels and drawn through a membrane to one of the other channels to assist in positive pressure driven filtration by using the osmotic pressure, concentration, or preferential solubility difference between the retentate and permeate flow streams thereby increasing or altering the flux through the membrane separating the flow streams.

A sterile solution product bag includes sterilization grade filter integrated directly into the product bag such that microbial and particulate matter filtration can be performed using the filter directly at the point of fill. The filter can include a hollow fiber filter membrane contained in a stem connected to a bladder of the product bag.

The present disclosure relates, according to some embodiments, to systems, apparatus, and methods for fluid purification (e.g., water) with a ceramic membrane. For example, the present disclosure relates, in some embodiments, to a cross-flow fluid filtration assembly comprising (a) membrane housing comprising a plurality of hexagonal prism shaped membranes (b) an inlet configured to receive the contaminated fluid and to channel a contaminated fluid to the first end of the plurality of hexagonal prism shaped membranes, and (c) an outlet configured to receive a permeate released from the second end of the plurality of hexagonal shaped membranes. The present disclosure also relates to a cross-flow fluid filtration module comprising a fluid path defined by a contaminated media inlet chamber, a fluid filtration assembly positioned in a permeate chamber and a concentrate chamber.

A ceramic filter membrane module enables a fluid to be filtered, such as raw water, with higher efficiency using multiple ceramic filters in a housing. As the diameter of a through-hole located at the center is considerably larger than the diameter of the surrounding flow path, water pressure pushing the raw water is applied from the through-hole at the center toward the outside of a filter body, such that the raw water passes through the filter body smoothly, thereby improving the purification efficiency and uniformly setting the overall flow direction of the raw water. As packing members are installed and fixed between the housing and the ceramic filters, sealing of the incoming raw water and the filtered water becomes more effective, such that the risk of leakage is reduced. As a plurality of ceramic filters are housed in a single housing, economic benefit can be achieved.

A water purification cartridge, and water permeate tubes and end caps for use therewith, are provided. An exemplary water purification cartridge has a central core with at least a first pair of permeate water tubes disposed about a central channel and a membrane assembly wrapped around and covering the central core. The membrane assembly includes at least a first membrane structure wrapped around a first permeate water tube, thereby creating a first permeate water tube assembly, and a second membrane structure wrapped around a second permeate water tube, thereby creating a second permeate water tube assembly. The first and second membrane structures are different. In another embodiment, a water purification cartridge comprises a central core with at least a first pair of permeate water tubes and a membrane assembly wrapped around and covering the central core, with each of the permeate water tubes having a generally tear-drop cross-sectional shape.

A gas separation apparatus includes a separation membrane module including at least one gas separation membrane element in a housing, a casing for blocking external air, and a heat source unit for adjusting a temperature of a heat medium with which the casing is filled. The casing holds greater than or equal to two separation membrane modules.

A tangential flow filtration manifold takes a modular form for interconnection in a manifolded arrangement for aggregating a total filtration area of the aggregate filter (membrane) surface. A plurality of modular TFF cassette filters may be or stacked on the TFF manifold such that it allows the number of interconnected filters, as well as the membrane surface area within each cassette, to be readily reconfigured. A single output, or filtrate connection on the TFF manifold simplifies fluidic plumbing connections for directing and gathering the filtrate (permeate) produced as output.
