Abstract: Fluid reactors include a sealed housing enclosing a reactor core that includes at least one substrate-free multichannel reactor core element. Each reactor core element is made from a non-substrate mounted, open pore cellular network material having an asymmetric, tortuous, bi-continuous two-phase material structure and contains multiple perforating fluid channels. Multiple reactor core elements can be serially and/or parallelly piped in a sealed manner to form a reactor core for a fluid reactor with a higher production capacity.

Abstract: An organization's security data is compared to an aggregation of multiple organizations' security data. Security data is received from multiple organizations having organizational characteristics. The received security data is aggregated based on the organizational characteristics to generate sets of aggregate data associated with the organizational characteristics. A query is received from an organization of the multiple organizations. The query specifies a particular organizational characteristic. A set of aggregate data associated with the specified organizational characteristic is identified. A representation of the organization's security data in relation to the identified set of aggregate data is generated. The representation is transmitted to the organization in response to the query.

Abstract: Arrangements and methods for contacting a gas and a liquid involve transferring a gas from one side of a pleated fluid treatment medium, through the fluid treatment medium, and into a liquid on the other side of the pleated fluid treatment medium to form a solution of the gas in the liquid.

Abstract: A fluid treatment element comprises a fluid treatment pack including a fluid treatment medium. The fluid treatment pack has a hollow interior and a barrier is disposed in the hollow interior. The barrier separates a blind region in which fluid cannot flow between the hollow interior and the fluid treatment pack from an open region in which fluid can flow between the hollow interior and the fluid treatment pack and prevents fluid from flowing between the blind region and the open region. The fluid treatment pack also has an end region having a sealed end. The fluid treatment element defines a flow path for process fluid to be treated passing in a lengthwise direction through a portion of the fluid treatment pack.

Abstract: Disclosed is a fluid treatment element, such as a filter element, operable in a dead end mode or a crossflow mode. In certain embodiments, the fluid treatment element includes a multilayer composite formed into axially extending pleats. In certain other embodiments, adjoining pleats are in a laid-over state and pressed against each other over a substantial portion of their height. The fluid treatment element can be compact yet have a large surface area available for fluid treatment. Also disclosed are a fluid treatment element and a method, particularly an all fluoropolymer fluid treatment element and a method, for diffusively transferring material from one fluid stream to another fluid stream, for example, for transferring ozone into water. Further disclosed are a device and method for crossflow cleaning of fluid treatment elements.

Abstract: A fluid treatment element is adapted for cross flow filtration which includes a fluid treatment pack having first and second lengthwise ends, a fluid treatment layer that may be pleated, a first mesh layer disposed on a first side of the fluid treatment layer and a second mesh layer disposed on the second side of the treatment layer, the element defining a flow path for a process fluid to be treated passing in a lengthwise direction of the fluid treatment element inside the first mesh layer and a flow path for permeate passing through the second mesh layer. The first mesh layer may open onto the first lengthwise end with the second mesh layer including sealant at the first lengthwise end such that fluid can flow through the first lengthwise end into the first mesh layer but not into the second mesh layer. The element may include a core having a blind region in which fluid cannot pass therethrough and at least one regions where fluid can pass through the core.
