A gas replenishment component for an electronic enclosure is described. A main body defines a containment volume. The main body is sealed about the containment volume. A charging gas is contained in the containment volume. The containment volume has less than 5% N. The main body defines a diffusive area that is permeable to the gas. A reversible seal obstructs the diffusive area.

Gas replenishment component for an enclosure

Some embodiments of the technology disclosed herein relate to a system having a hydrodynamic separator element defining an element inlet and an element outlet. The element outlet has a first element outlet and a second element outlet. The hydrodynamic separator element has a plurality of curved microfluidic channels in fluid communication. Each of the plurality of microfluidic channels are arranged to operate in parallel. Each microfluidic channel defines a channel inlet downstream of the element inlet and a channel outlet having a first channel outlet upstream of the first element outlet and a second channel outlet upstream of the second element outlet. A flow characteristic sensor is in sensing communication with the separator element. A controller is in data communication with the flow characteristic sensor, where the controller is configured to provide a first alert upon the flow characteristic being outside a first threshold.

Maintenance of hydrodynamic separators

A filter material for use in fuel-water separation has a particle filtration layer and a coalescing layer downstream of, and coupled to, the particle filtration layer. The particle filtration layer is substantially constructed of binder fibers and media fibers. The coalescing layer has at least 70% glass fibers by weight. As another example, a filter material for liquid fuels has a particle filtration layer and a coalescing layer downstream of the particle filtration layer. The particle filtration layer has binder fibers and media fibers and is substantially free of meltblown materials. The ratio of air permeability of the particle filtration layer to air permeability of the coalescing layer ranges from about 3:1 to about 15:1.

Composite media for fuel streams

Embodiments herein relate to systems for detecting air bubbles in fluids. In an embodiment, a fluid system aeration detector is included having an optical air bubble sensor. The optical air bubble sensor can include a light source, a light detector, and a sensor controller. The sensor controller can be in signal communication with the light detector and can be configured to detect air bubbles based on the signals received from the light detector. The sensor controller can further be configured to estimate an amount of aeration of a fluid based on the detected air bubbles. Other embodiments are also included herein.

Air bubble sensing systems and related signal processing

Embodiments herein relate to water in fuel sensing systems that can be mounted on-vehicle. In an embodiment, a water in fuel sensing system is included having a light source, a light detector, and a sensor controller, wherein the sensor controller is in signal communication with the light detector and the sensor controller is configured to evaluate signals received from the light detector, identify water droplets based on the signals received from the light detector, record information regarding the classified water droplets, and generate an estimate of an amount of water in a fuel. Other embodiments are also included herein.

On-vehicle water in fuel sensing system and related signal processing

The current technology relates to filter media configurations where the filter media has a surface with a treatment that increases the roll off angle of the surface for a 50 μL water droplet when the surface is immersed in toluene. Some example filter media have a fluted configuration, and some example filter media have multiple layers. Filter media having multiple layers can be single facer media, for example, where one layer is planar and another layer is fluted.

Filter media configurations

A substrate for use in a filter media including, for example, in a hydrocarbon fluid-water separation filter; methods of identifying the substrate; methods of making the substrate; methods of using the substrate; and methods of improving the roll off angle of the substrate. In some embodiments, the substrate includes a hydrophilic group-containing polymer or a hydrophilic group-containing polymer coating.

Hydrocarbon fluid-water separation

A system for producing steam includes a steam generator with steam output; a membrane filtration system in fluid communication with the steam output and including a membrane filter with a permeate side and an opposing retentate side. The membrane filter includes a separation membrane constructed to reject organic molecules. The system may be used for removing organic compounds, such as anti-corrosion agents or contaminants, from steam.

A hydrocarbon-in-water purification system includes a high capacity hydrocarbon absorber stage having a high capacity hydrocarbon absorber material and an inlet configured to receive a hydrocarbon-in-water dispersion from a fuel system. A polishing hydrocarbon absorber stage is in liquid communication and downstream of the high capacity hydrocarbon absorber stage including polishing activated carbon. The high capacity hydrocarbon absorber material has a greater saturation capacity than the polishing activated carbon and the polishing activated carbon has a greater polishing capacity than the high capacity hydrocarbon absorber material. A method for controlling and managing the evacuation of water from the hydrocarbon-in-water purification system includes tracking the purification state of water volumes and the bed loading states of purification beds defined in the water filter.

Hydrocarbon-in-water purification system

A hydrocarbon-in-water purification system includes an anion exchange stage having an anion exchange resin and an inlet and a water permeate outlet and a hydrocarbon outlet. The inlet is in fluid communication with a hydrocarbon-in-water emulsion source.
