Abstract: A filter element for filtering a fluid that comprises a pleated filter media and a support structure. The pleated filter media comprises pleats that define an upstream gap along an upstream surface of the pleated filter media and a downstream gap along a downstream surface of the pleated filter media. The support structure extends along the downstream surface of the pleated filter media and supports the pleats. The support structure is folded into two layers comprising a first layer and a second layer within the downstream gap. The first layer inner surface and the second layer inner surface are positioned adjacent to each other within the downstream gap. The support structure comprises at least one spacer that increases a distance between the first layer outer surface and the second layer outer surface such that the differential pressure drop through portion of the support structure that is within the downstream gap is decreased.

Abstract: A reverse osmosis filter assembly for fluid filtration having a push-activated lock and release mechanism. A push filter design activates a floating key lock upon insertion and extraction, where the filter key may be used simultaneously as a lock and as an identifier for particular filter attributes. The filter base may be situated inline, and in fluid communication, with the raw water ingress, permeate egress, and reject water egress. The reverse osmosis filter housing assembly may be attached to, and removed from, the filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.

Abstract: A capture unit for use with an antimicrobial application unit may include an upstream filter and a downstream filter. The upstream filter may be positioned to receive effluent from the application unit and to filter solid components from the effluent. The resultant upstream effluent filtrate may then be passed downstream to the downstream filter. The downstream filter may be used to filter an antimicrobial component from the upstream effluent filtrate and the resultant downstream effluent filtrate may be suitable for disposal as wastewater discharge. The antimicrobial is preferably a quaternary ammonium compound, is more preferably an alkylpyridinium chloride, and is most preferably cetylpyridinium chloride.

The structures disclosed include: a stormwater insert container for installation within a storm drain designed for intake of high volumes of water; an angling filter plug mounting structure and pre-filter basket for a flush installation on a planar floor, such that the filtration media rests beneath the floor and releases filtered liquids into a drainage area; a trench filtration assembly for installation into a trench below surface level, such that the unfiltered liquid passes through the trench and a trench box disposed within the trench filtration assembly prior to passing through the filtration media into a drainage area; and a liner box assembly for installation over an opening made in a non-permeable liner for purposes of pre-filtering contaminated liquids as it flows through the liner box and subsequently the filtration media.

Abstract: A filter system for liquid media has a filter housing with housing pot and housing cover. The housing pot has a drainage channel with bottom-side drainage opening. A bottom end disk of a filter element has a closure element arranged off-center to a longitudinal filter element axis. The closure element, in predetermined installation position of the filter element, extends seal-tightly across or into the drainage opening. The bottom end disk has a cutout corresponding with a positioning aid of the housing pot. By screwing on the housing cover, the filter element moves with the housing cover axially toward the drainage opening and rotates until positioning aid and cutout engage and lock the filter element relative to the housing pot in a predetermined rotational position where the closure element is axially aligned with the drainage opening. The filter element moves with the housing cover axially into the predetermined installation position.

Abstract: Filter capsules for showers and sinks used in surgical settings, clean rooms and other contaminant-sensitive settings having modified outlets for improved splash control. Flat, concave, convex, asymmetric concave and asymmetric convex outlet inserts have pluralities of fluid bores with varying orientations to permit enhanced fluid flow control out of the filter capsules including divergent, convergent and mixed divergent/convergent fluid flows. An inlet with an axis offset at an angle to the longitudinal axis of the filter capsule body permits user control over the fluid flow strike point in a sink or shower stall via rotation of the capsule about the inlet connection point. A recessed outlet improves the prevention of contaminant dispersal by recessing the outlet away from contact points and potential contaminant sources.

In some embodiments, the handle is structured to house a filtration system. In some embodiments, the reservoir is structured to house a filtration system. A liquid may pass through the filtration system to become treated before being stored in the lower chamber.

Abstract: A system for filtering water in a spa that provides safety and greater filtration. The system may include a filter secured to a core. The core may include first and second cages with a plurality of openings allowing water to freely pass through the filter and core while preventing larger objects from passing through. The first cage may provide an orientation feature to position the filter in one direction. The second cage may hold mineral cartridges. The core may be secured to a fitting that is secured to the suction line of a spa via a ratchet like engagement feature. The fitting and core prevent back out of the core unless manually overriding the arm on the core which engages fins on the fitting. The filter may be removed and replaced while the core remains in place providing safety to the user. A cap secures the whole assembly into place.
