The present invention relates to a support for a filtration membrane configuration formed with a first set of projections and a second set of projections in opposite directions. At least some of the first projections may be shaped with top areas forming contact face towards a filtration membrane configuration. The support for a filtration membrane may be formed with a first set of projections and a second set of projections in opposite directions, where at least some of the first projections are connected to a porous sheet forming support for said filtration membrane. The filtration membrane may be positioned directly on the porous sheet, or other in a sandwiched construction including other elements.

The present disclosure provides devices and methods for filtering a fluid. An example device can include a first end configured to be joined to a first segment of a pipe. The first end can include a first opening for receiving the fluid. The device can also include a second end configured to be joined to a second segment of the pipe. The second end can include a second opening for transmitting the fluid. A filtering segment can be disposed between the first end and the second end. The filtering segment can include a plurality of fiber filters oriented substantially perpendicular to a direction of flow of the fluid in the pipe. A fiber filter of the plurality of fiber filters can include a mycomaterial and a carrier material configured to provide nutrients to the mycomaterial.

A filter structure includes a housing having an inlet and an outlet; a first filter embedded in the housing and including a polymer membrane for filtering a first fluid flowing from the inlet into the housing; and a second filter embedded in the housing, filtering a second fluid filtered by the first filter, and including mesoporous silica nanoparticles (MSN).

A gas separation method includes supplying a mixed gas to a zeolite membrane complex and permeating a high permeability gas through the zeolite membrane complex to separate the high permeability gas from other gases. The mixed gas includes a high permeability gas and a trace gas that is lower in concentration than the high permeability gas. The molar concentration of a first gas included in the trace gas in the mixed gas is higher than the molar concentration of a second gas included in the trace gas in the mixed gas. The adsorption equilibrium constant of the first gas on the zeolite membrane is less than 60 times that of the high permeability gas. The adsorption equilibrium constant of the second gas on the zeolite membrane is 400 times or more that of the high permeability gas.
