    Abstract: Various implementations include a reversible flow sampler including a housing, a housing cover, and a shuttle. The housing defines a sampler chamber with an inlet and an outlet, a first opening, and a second opening. The shuttle is movably disposed within the housing and coupled to the housing cover. The shuttle has a first shuttle position and a second shuttle position. In the first shuttle position, the shuttle fluidly connects the first opening with the sample chamber inlet and fluidly connects the second opening with the sample chamber outlet. In the second shuttle position, the shuttle fluidly connects the second opening with the sample chamber inlet and fluidly connects the first opening with the sample chamber outlet.

    Abstract: A spiral wound membrane module has a brackish water RO or NF membrane combined with a permeate carrier having a narrow spacing between membrane contacting elements. The membrane may have water permeability (A-Value) of at least 8*10−5 cm/s/bar at 25° C. The membrane may have salt diffusion rate (B-Value) of at least 0.5*10−5 cm/s at 25° C. The permeate carrier may have a density of 54 wales per inch or more of a gap between adjacent ribs of 215 um or less. The permeate carrier may have a channel cross-sectional area of 16*10−9 m2 or more. Water is fed to the module at a high feed pressure, for example a pressure of at least 50 bar, optionally up to 120 bar. Retentate may be discharged at a concentration of 100 g/L, 130 g/L, or 150 g/L or more.

    Abstract: Various implementations include a device for analyzing total organic carbon (TOC) within a fluid. The device includes a primary container, an input conduit, and an output conduit. The primary container is hollow and has a primary side wall and a primary end wall. The primary side wall has an inner surface defining a primary cavity and an outer surface opposite and spaced apart from the inner surface. The primary end wall includes a septum that is resiliently penetrable by an analyzer needle of a grab analysis port of a TOC analyzer. The input conduit has an input lumen. The input conduit extends through the primary container such that the input lumen is in fluid communication with the primary cavity. The output conduit has an output lumen.
