A water filter medium container includes a removable upper cover and a removable lower cover. The container includes a tube defining a filter medium compartment operative to receive a replaceable filter medium. A first containment element may be placed between the upper cover and the tube. A second containment element may be placed between the lower cover and the tube. The water filter medium container may be adapted to be placed in a water container.

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.

A fluid management system including an inlet configured to receive pre-processed fluid is provided. The system includes a filtering apparatus configured to remove contaminants from the pre-processed fluid. The filtering apparatus includes a plate having a first opening. A first manifold pipe is disposed on the plate and includes one or more perforations and a second opening at least partially aligned with the first opening. A second manifold pipe is disposed on the plate and includes one or more perforations. Filter media is disposed between the first manifold pipe and the second manifold pipe and is configured to separate the contaminants from the pre-processed fluid. The system also includes an outlet coupled to the second manifold pipe to receive processed fluid from the filtering apparatus.

The present disclosure relates to a filter. According to the present disclosure, there is provided a filter including: an upper body whose interior is filled with a filter medium; a lower body located under the upper body in such a manner as to be open on top and bottom thereof; and an escape prevention member located inside the lower body to allow sludge and a fluid to be introduced into the lower body and to prevent the sludge from escaping from the lower body, wherein the escape prevention member may include: a support plate fixed to the inside of the lower body and having a through hole formed at the center thereof; a center pipe fixed to top of the support plate and having a lower hole formed on the bottom thereof in such a manner as to communicate with the through hole and at least one or more connection holes formed on one side thereof; and a backflow prevention ball movable inside the center pipe in such a manner as to selectively open and close the lower hole to prevent the fluid from flowing back.

Embodiments of the present disclosure describe filter agitators, filtration units comprising the filter agitators, methods of using the filter agitators, and the like. In certain embodiments, the filter agitators comprise a plurality of first fins extending outwardly from a central vertical axis and arranged in a plane oriented substantially perpendicular to the central vertical axis, wherein the plurality of first fins is configured to promote laminar flow of a fluid flowing in a first direction and induce turbulent flow of a fluid flowing in a second direction; and optionally a plurality of second fins positioned above the plurality of first fins and extending outwardly from the central vertical axis, wherein the plurality of second fins is configured to induce or further induce turbulent flow.

A fluid management system can include a first chamber, a diffusion plate positioned in the first chamber configured to receive fluid and to direct the fluid along a bypass fluid flow path or a primary fluid flow path, a riser pipe positioned within the first chamber that conveys fluid from the diffusion plate into a second chamber, and a filtering apparatus positioned in the second chamber. The filtering apparatus can include a plate having a first opening, one or more modules coupled to the plate having one or more perforations and a second opening corresponding to the first opening, and filter media disposed adjacent to the one or more modules, and a slab positioned above the filtering apparatus.
