Provided are an extraction structure, an extraction module, and a liquid pretreatment device relating to the liquid component testing technical field. The extraction structure comprises a cavity and a first pore passage. The extraction module comprises an extraction module body, successively bottom up, including a first cavity provided therein with a second filter layer, a first pore passage provided therein with a first filter layer, and a second cavity provided therein with an extractant layer and a porous filter disc; the first and second filter layers contain therein an expansive agent; and the diameter of the first filter layer is smaller than that of the second filter disc. The liquid pretreatment device comprises a storage tank, a transfer device and the extraction module. Between the transfer device and the extraction module is provided a filter membrane for filtering and supporting.

A portable drinking water filter system, such as a pitcher, having a sleeve and a floatable body including a filter opening configured to receive a water filter, the floatable body having a seal extending outward from an outer surface of the floatable body. The floatable body is disposed in a sleeve cavity such that a body seal engages the sidewall and restricts water from passing between the floatable body and the sidewall. The seal is configured to create friction with the sidewall, wherein the friction created when the floatable body rises in the sleeve is different than when the floatable body lowers in the sleeve. The friction created when the floatable body rises in the sleeve is greater than when the floatable body lowers in the sleeve, allowing the floatable body to auto-retract toward a cavity base without burping.

A method of filtering a wastewater stream and a filter media comprising a non-woven felt material for filtering particles from a wastewater stream wherein the non-woven felt material filter is positioned within a wastewater stream from a washing machine and wherein the filter is positioned downstream of a washing machine wastewater drainage outlet. The filter media may be configured for use with a gravity based wastewater filter mountable to a surface external to the washing machine or may be configured for use with a motorized wastewater filter mountable to a surface external to the washing machine.

An effluent collector includes a filtrate receiving portion having a filtrate opening, and a pressate receiving portion having a pressate opening. The effluent collector includes a diverter barrier adjustably positioned above the pressate receiving portion. The diverter barrier is configured to adjustably direct at least a portion of a flow path toward or away from the pressate receiving portion.

Embodiments of the present disclosure include a screen basket apparatus includes a substantially vertical cylindrical frame and a synthetic screening surface secured to the frame. The synthetic screening surface may be configured to separate carbon or resin from a slurry of a carbon-in-leach, carbon-in-pulp, resin-in-leach, or resin-in-pulp material as fluid flows from outside to inside the screen basket apparatus such that carbon or resin is retained on an external surface of the synthetic screening surface. The cylindrical frame may be a grid frame and the synthetic screening surface may include a plurality of replaceable screen assemblies attached to the grid frame. The grid frame may include a plurality of openings and each of the plurality of openings is configured to receive a respective one of the plurality of replaceable screen assemblies. The synthetic screening surface may include injected molded thermoplastics, thermoset polyurethanes, and/or other polymeric materials.
