An inorganic membrane filtration article and methods for making the same. The membrane filtration article includes a sintered flow-through ceramic honeycomb with a plurality of partition walls defining a plurality of open channels from an inlet end of the honeycomb to an outlet end of the honeycomb. The honeycomb is formed from a cordierite composition with low-sodium and/or low-potassium content for enhanced filtration performance.

A filter for the filtration of a fluid, such as a liquid, includes or is composed of a support element made of a porous ceramic material, the element exhibiting a tubular or parallelepipedal shape delimited by an external surface and including, in its internal portion, a set of adjacent channels with axes parallel to one another and separated from one another by walls of the porous inorganic material, in which at least a portion of the channels and/or at least a portion of the external surface are covered with a porous separating membrane layer, wherein the separating membrane layer is made of a material essentially composed of silicon carbide (SiC), and the content by weight of elemental nitrogen of the layer constituting the porous separating membrane layer is between 0.1% and 2%.

A humidifier, a device including a fuel cell, and a motor vehicle. The humidifier of the includes at least one humidifying duct and is designed in such a way that a first gas to be humidified can be conducted in the humidifying duct in a direction of flow and, separated by a water-permeable material, past a humidifying second gas so that water is transferred from the second gas to the first gas. The humidifier includes a cross-sectional area of the humidifying duct available to the first gas tapers in the direction of flow. The fact that the cross-sectional area tapers results in a drop in pressure along the humidifying duct, and the drop in pressure reduces, compensates or overcompensates an increase in pressure resulting from the increasing humidification, so the partial difference in pressure between the first gas and the second gas remains large over the distance of the humidifying duct in spite of the transfer of humidity.

A ceramic membrane filter includes a porous substrate including cells through which a fluid flows, an intermediate membrane formed on the porous substrate, and a separation membrane formed on the intermediate membrane. In this ceramic membrane filter, the percentage of the number of cells having cracks with a size of 4 μm or less relative to the total number of cells is 9% or less.

The subject of the invention relates to a separating element comprising: an inorganic one-piece rigid porous support (2) having, on one side, a first outer planar surface (3) and, on an opposite side, a second outer planar surface (4); at least two circulation ducts (6) for the liquid medium that are formed in the porous support so as to each have a rectangular cross section; at least one internal connection system for the distribution (10) of the liquid medium in a series of circulation ducts, and at least one internal connection system for the collection (12) of the retentate coming from the series of circulation ducts, the internal connection system for the distribution (10), the circulation ducts (6) and the internal connection system for the collection (12) being provided with at least one separating layer continuously deposited between the inlet (11) and the outlet (13) of the porous support; and a collection system (7) for the permeate that has passed through the separating layer or layers.

The present invention is concerned with the treatment of produced water, that may be obtained from a chemically enhanced oil recovery process using viscosity-increasing polymeric compounds. Said treatment comprises particularly the steps of obtaining a produced water, such as from an oil-water mixture recovered from an oil-bearing formation, wherein the produced water comprises the viscosity-increasing polymeric compounds; and, of directing the produced water to a specific filtration device, and subjecting the produced water to filtration, for obtaining a retentate stream and a permeate stream. Said process allows particularly obtaining a permeate comprising the viscosity-increasing polymeric compounds, said permeate being substantially free of suspended solids, free oil and emulsified oil.

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.

The invention relates to a method for transporting a filter module (10) comprising an elongate and tubular housing (12) and at least one flat filter segment (26) arranged in the housing (12), said method comprising the following steps: a. arranging the filter module (10) in a transport container (44); and b. orienting the filter module (10) in the transport container (44) such that a plane of the filter segment (26) is arranged at least approximately vertically in the normal transport position of the transport container (44).

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.
