    Abstract: A system for producing steam includes a source of superheated water with superheated water output; a membrane filtration system in fluid communication with the superheated water 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 superheated water to produce steam. A method for producing steam includes directing a cross-flow of heated pressurized water including a first concentration of an organic compound across a membrane filter. The membrane filter includes a separation membrane constructed to reject the organic compound; and one or more support layers adjacent the separation membrane. A steam permeate including a second concentration of the organic compound is collected, where the second concentration is lower than the first.

    Abstract: Porous ePTFE articles coated with a hydrophilic coating are provided. The coating may be modified by covalent modifications to the PVOH coating. Covalent modifications may include small molecule grafting, polymer grafting to or from the PVOH backbone, crosslinking of the polymer via thermal or photochemistry, and the like, and combinations thereof. A second polymer coating may be applied onto the PVOH coating. The second polymer may be added, for example, by using a saturation coating technique such as dip coating or spray coating to saturate a PVOH coated ePTFE substrate with a second polymer carried by a fluid. Application of the second polymer may form a second conformal coating over the first PVOH coating.

    Abstract: The present disclosure relates to a cassette assembly. An inlet cassette plate defines an inlet cassette inlet flow path and an inlet cassette outlet flow path. An outlet cassette plate is configured to be arranged in a stack with the inlet cassette plate. The outlet cassette plate defines an outlet cassette inlet flow path configured to be laterally aligned with the inlet cassette inlet flow path, and an outlet cassette outlet flow path configured to be laterally aligned with the inlet cassette outlet flow path. An inlet plug is configured to be inserted in the outlet cassette inlet flow path. An outlet plug is configured to be inserted in the inlet cassette outlet flow path. The inlet and outlet plugs are configured to be removable and reinsertable. A separation layer is disposed between the inlet cassette plate and the outlet cassette plate.

    Abstract: 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.

    Abstract: A filter including a first flow face extending along a lateral direction and a transverse direction of the filter, wherein the first flow face includes at least one contaminant retention layer first edge and at least one flow defining layer first edge, a second flow face spaced in an axial direction from the first flow face, wherein the second flow face extends along the length and the width of the filter and includes at least one contaminant retention layer second edge and at least one flow defining layer second edge, at least one contaminant retention layer extending from the contaminant layer first edge to the contaminant layer second edge, and at least one flow defining layer adjacent to at least one of the contaminant retention layers, the at least one flow defining layer extending from the flow defining layer first edge to the flow defining layer second edge, wherein at least one of the flow defining layers defines at least one fluid flow path in the axial direction as fluid moves from the first flow face toward the second flow face.
